"TRIG" or "the Company", a London-listed investment company advised by InfraRed Capital Partners ("InfraRed") as Investment Manager and Renewable Energy Systems ("RES") as Operations Manager.

Announcement of Interim Results

Highlights for the six months ended 30 June 2023

Healthy cash generation from underlying projects:

o  Dividend cover of 1.7 times in the period (30 June 2022: 1.4 times), or 3.0 times before the repayment of project level debt

o  Strong inflation linkage, with over 50% of revenues directly linked to inflation over the next ten years

o  Fixed interest rate borrowings across the project companies

o  £119m of project level debt principal repaid. Project level gearing reduced from 38% to 37%

o  £65m reinvested in construction projects using £54m of surplus cash generated during the period

o  The Company's £750m RCF as at 30 June 2023 was £410m drawn - expected surplus cashflow to enable the reduction of RCF borrowings after meeting the Company's investment commitments

Resilient earnings and Net Asset Value ("NAV"):

o  Earnings per ordinary share of 1.1p (30 June 2022: 17.9p)

o  NAV per ordinary share of 132.2p as at 30 June 2023 (31 December 2022: 134.6p)

o  Reduction in NAV driven by increase in discount rate to 7.9% (31 December 2022: 7.2%) partially offset by an increase in long-term inflation assumptions

o  Increase in discount rates principally reflects higher interest rates (weighted to the UK) and also includes higher returning development stage battery storage projects

o  NAV reduction also offset by active management initiatives, including delivering projects through construction and securing attractive fixed power pricing

o  Portfolio valuation of £3,671m as at 30 June 2023 (31 December 2022: £3,737m)

A technologically and geographically diversified portfolio of 2.8GW of renewable energy assets:

o  1,040,000 tonnes of CO₂ avoided during the period (30 June 2022: 960,000)

o  2,919GWh of clean energy generated during the period (30 June 2022: 2,747GWh)

o  Completion of five construction projects in H1, including solar projects in Spain and an onshore wind farm in Sweden, commissioning 301MW of new capacity

o  1.7m homes (equivalent) powered with renewable electricity (30 June 2022: 1.6m)

o  Below budget generation in the period, predominantly driven by low wind resource in the UK, partially moderated by portfolio diversification with the solar portion of the portfolio ahead of budget

Richard Morse, Chair of TRIG, said:

"TRIG's portfolio continues to generate strong cash flows, benefiting from its positive inflation correlation, low sensitivity to interest rate costs, and active management from InfraRed and RES. The combined investment and operational experience of our Managers is a competitive advantage, as TRIG continues to play its part in delivering sustainable energy across several European markets."

Richard Crawford, Head of Energy Income Funds, InfraRed, said:

"The Managers continue to drive value through commercial and technical enhancements, including securing higher power prices and increased energy output. We prioritise the use of TRIG's strong cash flow generation to reduce group-wide borrowings. The inflation linkage within TRIG's revenues and the diversification of our portfolio across geographies and technologies means we are well-positioned to deliver shareholder value in a challenging macro-economic backdrop."

Chairman's Statement

TRIG's portfolio demonstrates its resilience through the economic cycle, underpinned by the positive inflation correlation of its revenues and low exposure of its cash flows to rising interest rates.

Over the next ten years, more than 50% of forecast revenues are directly linked to inflation through subsidy support mechanisms providing a natural hedge to increasing return expectations. Despite these characteristics, we have not been immune to the sustained trading of share prices at discounts to Net Asset Values, as seen across the real assets investment company sector. In a changing macroeconomic environment, we maintain our focus on capital allocation together with active operational and financial management.

Earnings in the six months to 30 June 2023 were 1.1p per share. Underlying portfolio performance remains strong, with cash flows benefitting from increases in index-linked subsidies as well as the exposure to wholesale power prices, despite lower than expected wind resource. Portfolio Valuation has slightly declined as valuation discount rates have been increased, reflecting the higher returns environment which is significantly offset by the strong inflation linkage in the portfolio. As at 30 June 2023, the portfolio discount rate was 7.9% and the Company's NAV was 132.2p per share. Further explanation of the Company's financial results is provided in the Investment Report.

Net cash flows from the Company's projects are very healthy, covering the cash dividend 1.7 times. Operational cash flow generated in the period before repayment of project-level debt in the period was £264m, representing 3.0 times cover of the dividend. We are pleased to reconfirm the 2023 dividend target of 7.18p per share (2022: 6.84p per share).

We have applied surplus cash flows from the portfolio to fund existing construction commitments and in time, as construction commitments are met, we expect surplus cash flows to reduce short-term debt. Beyond this, the Investment Manager adopts a disciplined approach to further capital outlay, where, together with the Board, it also considers share buybacks alongside potential new investments as well as disposals to generate cash for such allocations in seeking the best return for shareholders.

Balance sheet discipline is reflected across the portfolio with project debt almost entirely fixed rate and fully amortising over the remaining subsidy periods without refinancing risk. This protects the portfolio's cash flows from interest rate movements.

Diversification remains core to TRIG's strategy, and our operational portfolio continues to expand with the commissioning of five projects constructed in Sweden and Spain. The development of our two near-term battery storage projects in the UK continues to progress well.

TRIG's Managers work both to preserve and enhance the portfolio's value. This work encompasses both technical enhancements such as improvements to blade aerodynamics that increase energy output, and commercial enhancements like the long-term corporate Power Purchase Agreement TRIG entered into during the period that helps manage variable power price exposure. We expect another opportunity to enhance shareholder value will come from the repowering potential of our older assets beyond that recognised in the Company's Portfolio Valuation.

Energy policy evolution remains an area of attention. Reviews of electricity market arrangements are ongoing in the UK and the EU, including the consideration of wholesale pricing mechanisms, as expanded upon in the Investment Report.

Klaus Hammer retired from TRIG's Board of Directors in May 2023. On behalf of the Board, I would like to thank him for his nine years of service to TRIG's shareholders and broader stakeholders. I also welcome Selina Sagayam who was appointed to the Board in March 2023. Selina has extensive legal and ESG experience, and she chairs our newly established ESG Committee. TRIG published its fourth annual Sustainability Report in May, underscoring our commitment to responsible investment, which this new committee will oversee.

During the period, Jaz Bains stepped down from the leadership of the Operations Manager's team. I extend the Board's thanks to Jaz for his significant contributions to TRIG since its launch in 2013. He hands over to Chris Sweetman, who has been leading the day-to-day management as a senior member of the RES team alongside Jaz since TRIG's IPO. Jaz remains on TRIG's Advisory Committee.

In the ten years since TRIG's IPO, the Company has delivered shareholders a return of 8.8% p.a.¹, grown the dividend by 20% and created the largest diversified portfolio of renewables infrastructure projects of its peers, spanning six European countries and four technologies. Looking forward, as countries across Europe decarbonise to reach net zero emissions by 2050, renewables remain at the heart of public policy and the opportunity set is greater than ever. I firmly believe that TRIG's priorities of diversification, value enhancement and effective capital allocation will continue to generate resilient returns for our shareholders.

Investment Report

Financial highlights

The Company's portfolio generated strong cash flows in the first half of 2023. Operational cash flow of £264m² represents 3 times cover of the £87m cash dividend paid to shareholders. Operational cash flows were used to repay £119m portfolio-level debt. After operating and finance costs, the Company's net cash flow of £145m (H1 2022: £107 million) during the period covered the cash dividend 1.7 times.

Looking forward, cash flows are expected to continue to be supported by the portfolio's strong inflation linkage and power price levels above historical averages. This has provided resilience to valuations in the face of marked increases in nominal return requirements, with valuations softening only slightly in the first half of the year as the higher returns required by investors have been mitigated by higher forecast cash flows. This resilience can be further demonstrated by looking back over the last 18 months where valuations have increased due to increases in forecast cash flows, despite the Company's 1.0% increase in valuation discount rate applied over this period.

The Company's Net Asset Value as at 30 June 2023 was 132.2p per share (31 December 2022: 134.6p per share) and the Company's Portfolio Valuation was £3,671 million. Earnings for the period were 1.1p per share (H1 2022: 17.9p).

This resilient underlying financial performance has been the result of:

-     Continued active financial and operational management of TRIG's portfolio, including:

·      The delivery through construction into operations of four solar projects in Spain and one onshore wind farm in Sweden.

·      Fixing power prices for several projects at attractive prices, including the signing of a ten-year corporate power purchase agreement, which secured an attractive fixed tariff for Blary Hill onshore wind farm.

-     Reintroduction of historical feed-in tariffs on older solar projects thereby reversing the retroactive changes introduced by the French Government.

-     Increases in index-linked subsidies and strong wholesale power prices flowing through to revenues.

-     Fixed interest rate borrowings across the project companies and limited refinancing risk across the project debt in the portfolio, largely removing sensitivity to recent increases in interest rates.

-     Strong pricing performance of Renewable Energy Guarantees of Origin certificates ("REGOs") in the UK and Guarantees of Origin certificates ("GoOs") in the EU, resulting in increased forecast revenues.

This has been partly offset by below budget generation, predominantly driven by low wind resource in the UK relative to long-term forecasts.

Macroeconomic movements included:

-     Decreases in short- and medium-term power price forecasts across the markets where TRIG has investments, which reduced the Portfolio Valuation by 3.5p per share. However, relative to historical norms, power prices remain elevated following the substantial increases seen in 2022. The decreases in 2023 significantly reduce the impact of the windfall taxes introduced in 2022 on the Company's NAV.

-     The portfolio's weighted average discount rate has increased by 0.7% to 7.9%. This is mostly due to the Investment Manager increasing valuation discount rates for projects, by an average of 0.5% (UK +0.8%, EU +0.3%). This increase of 0.5% has reduced the Portfolio Valuation by 5.7p per share in the period. This reflects the increased return expectations for the portfolio whilst recognising the movement in government bond yields, particularly in the UK where there have been fewer renewables transactions on which to base valuations.

-     The valuation impact of the higher discount rate was substantially mitigated by increased near-term and longer-term inflation assumptions, which have increased the Portfolio Valuation by 3.9p per share as these inflation assumptions flow into revenue forecasts through index-linked subsidies and indirectly increase power price forecasts. Over 50% of the Company's forecasted revenues over the next ten years benefit from subsidy regimes with a direct link to inflation indices.

Greater detail on these movements can be found in the 'Valuation of the portfolio' section of the 2023 Interim Report.

Responsible management of the balance sheet is a key focus for the Company's Board and Managers, informing their approach to capital allocation in consideration of the current macroeconomic environment. In the current market context, managing short-term borrowings on its RCF (see below) and meeting the Company's construction commitments are the primary uses of excess cash flows from the portfolio.

The Company's underlying gearing at asset level continues to amortise and will be repaid debt during the remaining period of government subsidy and revenue support mechanisms.

TRIG utilises a RCF, which is used to make new investments and is repaid from surplus cash flows, equity fund raises or disposal proceeds. The RCF which was refinanced in February 2023, has total funding capacity of £750m and matures in December 2025. As at 30 June 2023, the RCF was drawn £410m, remaining broadly level over the period. Surplus investment cash flows have been used to fund the Company's construction activities during the period.

In H1 2023 construction spend of £65m was largely met by surplus operational cash flows generated of £54m. Committed spend on construction is reducing as projects come out of build, so it is expected that the construction commitments which are £150m over the next three years will be exceeded by surplus operational cash flows.

Investment highlights

TRIG consistently benefits from a large and diversified portfolio with investments spread across different geographies, technologies and revenue types to mitigate risk.

The Investment Manager takes a careful and considered approach to portfolio composition. New investments are appraised alongside alternative uses of the Company's surplus cash flows, in particular reducing RCF borrowings and the consideration of share buybacks.

The Managers' successful delivery of development and construction projects through to operations is a key driver to create value for shareholders. Several significant milestones were reached during the period, including the commissioning of the four Cadiz solar projects in Spain and the Grönhult onshore wind farm in Sweden. Adding 301MW of operational capacity to the portfolio, these projects strengthen and further diversify the Company's revenues. Approximately half of the construction risk premia across these investments has been released and reflected in an increase in the valuation of these investments. The remaining construction risk premia will be released as the energy yield and operational performance is further evidenced in steady state operations.

TRIG's ongoing construction projects also continued to progress well during the period. The first turbines were erected at Ranasjö and Salsjö (Twin Peaks) onshore wind farms in Sweden where operational take-over is scheduled for 2024.

Works are also being progressed to maximise the value of TRIG's existing assets. Repowering development works have commenced for the 38MW Altahullion wind farm in Northern Ireland. An agreement was also reached during the period to commence development work which leverages the grid connection and land space at the Cadiz solar projects through the addition of onshore wind, a process known as 'co-location'.

The development of the four two-hour duration battery storage projects acquired in late 2022 has also progressed well. The 74MW Ryton project, is expected to reach the Final Investment Decision ("FID") stage post period end. Additionally, a follow-on loan was added to the Phoenix mezzanine debt investment to enable our partner, Akuo, to build 25MW of new battery storage capacity at sites on Corsica and La Reunion.

The Investment Manager also considers opportunities to secure greater value for shareholders through divestments where a third party may attribute greater value to a project than recognised in the Portfolio Valuation. There may be selective opportunities to adjust the portfolio's composition by rotating out of certain assets and into diversifying, and potentially higher returning, opportunities.

Current outstanding commitments

The Company has outstanding investment commitments (for construction activities) of £146m relating to the Swedish onshore wind construction projects (Ranasjö and Salsjö), and two of the UK battery storage projects (Ryton and Drakelow), set out in the table below by expected due date. Further information is detailed on page 18 of the 2023 Interim Report. The Company's £750m committed RCF was drawn £410m as at 30 June 2023.

Revenue profile

TRIG benefits from diversification across several power markets, with projects in Great Britain, the Single Electricity Market (Northern Ireland and the Republic of Ireland), the main continental European power market (France and Germany), the Nordic market (Sweden) and the Iberian market (Spain).

TRIG's portfolio cash revenues, as well as benefitting from wholesale power prices, have substantial medium-term protection from movements in power prices as the portfolio receives a high proportion of its revenue from government subsidies such as Feed-in-Tariffs ("FiTs"), Contracts for Difference ("CfDs"), Renewable Obligation Certificates ("ROCs") or from selling electricity generated via Power Purchase Agreements ("PPAs") with fixed prices or from other hedges, together referred to as fixed revenues.

The Group³ receives a portion of its revenues in Euros; 42% of the portfolio by value is invested in Euro-denominated assets. The Group employs foreign exchange hedging to significantly mitigate the cash flow and valuation exposure to this risk, as expanded upon in the 'Valuation of the portfolio' section.

The Investment Manager implements the Company's foreign exchange hedging policy through Sterling-Euro swaps for up to four years forward. As a result of the interest rate differential between UK and the Eurozone, forward foreign exchange contracts over the next four years have been struck at levels better, in Sterling terms, compared to the foreign exchange rate as at 30 June 2023 and used in the Portfolio Valuation.

Principal risks and uncertainties

TRIG's principal risks, approach to risk management and counterparty exposures are unchanged to those set out in section 3.4 of the Company's 2022 Annual Report - Risks and Risk Management. Updates against the principal risks are summarised below.

In addition, in a macroeconomic environment with elevated inflation and rising interest rates, the correlation of portfolio returns to inflation and the Company's approach to long-term, fixed-rate and amortising structural debt are key risk mitigants.

Regulation and taxation

The risk of government or regulatory support for renewables changing adversely.

In 2022, prolonged high power prices saw governments across Europe intervening in energy markets, including through the introduction of 'windfall' taxes and levies on generators to, in the first instance, help fund financial support to ease the cost of electricity to end users. In the UK, the Electricity Generator Levy is in place until 2028. In the EU, many of these levies expired on 30 June 2023, with several countries not extending the period of application, including Germany. There remains a risk that further intervention may result if electricity prices were to increase significantly again; however, the price levels that have historically triggered intervention are not taken into account in the valuation of the Company's portfolio.

As detailed under Market Developments, the UK and EU governments are also assessing options to reform electricity markets, including how the wholesale electricity price is set and whether new long-term revenue support contracts should be made available to existing generators. TRIG's approach to diversify political and regulatory risk across jurisdictions helps to reduce the impact on the portfolio from individual risks at the national level.

Power prices

The risk of electricity prices falling or not increasing as expected.

Power prices have been particularly volatile since 2020, with periods of very low pricing experienced during the Covid pandemic and very high prices since the outbreak of the conflict in Ukraine.

Power prices trended lower during the first half of 2023 but remain elevated compared to historical levels. A combination of infra-marginal power price caps implemented in Europe and the Electricity Generator Levy in the UK reduced sensitivity to this change. Near-term forwards are now at levels consistent with, or below, government intervention thresholds.

There has been little change in the long-term fundamentals of power prices in the period, leading to limited movements in long-term power price forecasts compared to those as at 31 December 2022 in most geographies. We are yet to see the increase in supply chain costs and cost of capital flow through into forecasters' renewables deployment and electricity demand assumptions.

The valuation of the Company's portfolio overlays market derived forward prices to a blend of cannibalised power price forecast curves produced by three independent forecasters.

Production performance

The risk that portfolio electricity production falls short of expectations.

Weather resource was below budget in the period, particularly wind in the UK and Ireland. The overall shortfall against budget was moderated by portfolio diversification, particularly the solar portion of the portfolio which was ahead of budget for the period. Portfolio diversification has been enhanced in the period with the commissioning of the Cadiz solar projects in Spain and the Grönhult onshore wind farm in Sweden. Further, operational partners across the portfolio, including RES, continue to develop energy yield value enhancements to improve energy output.

Market developments

UK

In February 2023, the UK government published a summary of responses to the Autumn 2022 Review of Electricity Market Arrangements consultation, and at the same time reinforced the current pay-as-clear price setting mechanism as the most appropriate. One of the key areas which is subject to ongoing debate is the market structure and whether there remains one price across the whole of Great Britain, or there is a move to locational pricing with the island split into either several price zones or hundreds of price nodes.

A move to locational pricing may result in merchant power price revenues received by projects nearer demand centres increasing; but projects further from demand centres may see electricity offtake pricing fall. Should locational pricing be adopted, it is unlikely to be beneficial for most wind farms which tend to be in remote areas, although transitional arrangements may be adopted which could mitigate this risk.

A number of studies are currently underway in relation to the different market structures being considered. One such study has indicated that a move to locational pricing might result in savings for consumers; another indicates that locational pricing would be more expensive. In both cases, each study highlights significant unquantified risks with overhauling the market structure. It is also important to continue to appeal to wind farm developers and financiers, with signs already that wind farm development is reducing due to economic pressures. Further studies are expected to be published during the summer and a second industry consultation is expected in the autumn.

EU

Shortly following their consultation in February 2023, the European Commission proposed a number of possible reforms to power markets. Discussion of the reforms remains ongoing. These reforms indicate a desire to improve electricity pricing visibility for generators and customers through greater use of power purchase agreements with government guarantees, by strengthening power markets through grid infrastructure investment, by increasing the use of two-way Contracts for Difference for new build renewable projects, and in doing so protecting retail consumers.

Outlook

During a period of continued geopolitical and macroeconomic uncertainty, the Company's portfolio has again demonstrated its inherent resilience through strong cash generation. The strength of the Company's prudent capital structure, the inflation correlation within its revenue streams, and distinct investment strategy continues to be underscored in the current volatile market.

The opportunity to deliver higher returns from progressing late-stage development and construction assets means that the Company is well positioned to continue its track record of delivering income and capital growth. The active management of the portfolio includes the consideration of disposals where complementary to the Company's overall strategy.

The Managers' implementation of the Company's strategy through their approach to portfolio diversification, value enhancement and capital allocation seeks to maximise returns for shareholders. InfraRed's differentiated investment capabilities combined with RES' operational excellence, stand the Company in good stead to deliver a real value proposition to shareholders.

Operations Report

Operational performance

*     Includes compensated production due to grid curtailments, and other availability warranties and insurance

Overall, wind resource in most of the jurisdictions in which TRIG invests across Europe has been below budget in the period. The impact of a particularly poor wind resource period in the UK and Ireland has been moderated by the diversification of the portfolio in regions such as France, Germany and Sweden, where the negative variance to budget has been less, and the inclusion of solar in the portfolio, which outperformed budget.

Onshore wind

GB

Production in the GB region was adversely affected across the region by very low wind in the half year period. During this time a number of major component exchanges were undertaken so to minimise the lost production during the associated downtime compared to undertaking works when wind levels are more normal.

New Operations & Maintenance ("O&M") contracts were signed for three more of the seven UK and Ireland projects which were competitively tendered in 2022. These contracts leverage TRIG's portfolio size and purchasing power whilst capturing site-specific technical requirements.

A ten-year corporate PPA was signed to secure fixed revenue at an attractive price at TRIG's first subsidy-free wind farm in the GB region, Blary Hill.

Northern Ireland & Republic of Ireland

Generation in the region, which constitutes 4% of the portfolio, was below budget due to a mixture of low wind and major component replacements at older sites.

France

Sites in the north of France performed well, driven by strong wind resource and high availability. This was offset by below-budget production at the southern sites, which experienced a significant number of high wind events requiring preventative shut downs during Q1. Vannier, which completed construction in H2 2022, performed on budget.

Repowering activities on the four older southern sites continue, with grid connection secured for Claves in the period. Major components continue to be replaced to enable the projects to maximise the benefit from current high power pricing ahead of decommissioning and repowering. Dismantling of the first site is expected to commence in late 2024.

Sweden

Production was 7% under budget, due to low wind compared to long-term averages. Jädraås and the newly constructed Grönhult are located in different regions of Sweden, adding diversification to the production within the country.

Offshore wind

GB

Production was 9% below budget again due to low wind resource relative to long-term averages. Production was also adversely impacted at Beatrice by array cable issues which required some curtailment. Additional monitoring is planned to gather the required data to support the removal of this curtailment.

Improved terms were secured on a major O&M contract for one asset in the region, which will amount to significant savings over a period of ten years.

Proactive end of warranty inspections and negotiations across TRIG's offshore wind portfolio continue to maximise the long-term performance and value of these assets.

Germany

Production was 7% below budget, largely due to low wind resource and a grid outage at Merkur in Q1.

Leading edge protection works are being progressed at Merkur over the summer to protect the long-term integrity of the blades. These works are being conducted under warranty by the turbine provider and include protection against lost revenue.

At Gode 1, the grid operator has constructed and commissioned a new offshore substation for future neighbouring windfarms. In the years leading up to project completion, this will provide an alternative export route for Gode 1 in the event of an outage on its main substation, thereby reducing the risk of future grid losses. It also provides an alternative import route, which can be used to reduce downtime following grid outages.

Solar

GB, France & Spain

The solar portfolio outperformed budget, reinforcing the benefits of a diverse portfolio.

Within Spain, generating ahead of their takeover date in Q1, the four solar projects in Cadiz performed well, resulting in above-budget production in the period. The other Spanish solar project Valdesolar maintained very high availability and  its production was on budget in the period.

Within GB, a major panel replacement programme is underway at Parsonage following a successful warranty claim. The newer, more efficient modules are expected to improve future performance.

Manufacturer Exposure

It is important to work with a range of suppliers, and TRIG's portfolio is well diversified across a range of different models and vintages of wind and solar technology. TRIG has exposure to many different equipment manufacturers, with Siemens Gamesa Renewable Energy (SGRE) being the largest of these on a Portfolio Valuation basis. Issues with equipment inevitably occur from time to time across different manufacturers. The Company has not been materially impacted by these due to contractual protections in place and repairs / correction works being carried out. This includes a range of different contract types, some of which are long-term and all-inclusive, providing protection against expenditure and downtime. End-of-Warranty inspections are also pro-actively conducted, providing time for any issues to be rectified ahead of expiry. The combination of visibility across the TRIG portfolio, and RES's market awareness allows the Operations Manager to identify potential issues in advance and focus in on monitoring the areas with the greatest potential risks.

Construction

Arenosas, Malabrigo, El Yarte and Guita, the four Spanish solar projects located in Cadiz, successfully reached operations in Q1 2023. These projects significantly increase the size of TRIG's operational solar portfolio and strengthen its technological and geographical diversification. The independent Owner's Engineer will continue to be closely involved in the projects until the end of the construction warranty period, to ensure any defects are captured under the warranty and thereby protect long-term quality.

Following first export in October 2022, commissioning activities at the Swedish onshore windfarm Grönhult were completed in the period. The site achieved operational takeover in Q2 2023, culminating with a well-attended inauguration ceremony in June.

Swedish windfarms Ranasjö and Salsjö remain on target to take over in 2024. Turbine component deliveries are ongoing with the first turbines now erected. On- and off-site electrical works are progressing with energisation expected later this year.

Development

Design and procurement works on the first of the four storage development projects are well advanced with contracts expected to be placed and ground works commenced later this year. Activities on the latter projects will ramp up in line with their grid connection dates. 

Health & safety

Delivering high quality health and safety within the construction and operational portfolio is the top priority. The portfolio's asset managers promote a strong safety culture through a pro-active approach utilizing safety drills, training days, internal and external audits and other activities which complement core safety frameworks. The Operations Manager continues to engage with the asset managers to ensure sharing of best practice and lessons learned across the portfolio.

In H1 2023 a very low incident rate was achieved, with two Lost Time Accidents.

A selection of proactive health & safety measures from the period are included below:

-     Members of the Board visited Broxburn storage project in Scotland. Alongside the Managers they met with the site Operations & Maintenance and Asset Management teams, and reviewed the measures taken to mitigate inherent safety risks of a storage project

-     Project company directors continued to visit and undertake safety walks at both operational and construction projects, including the Cadiz and Ranasjö & Salsjö construction sites, where they met with the on-site teams

-     Welfare facilities were installed at four GB solar sites, providing improved workplaces for technicians. A full roll-out is planned following good feedback

-     One of TRIG's offshore wind projects provided assistance when a crew member on a local fishing vessel became critically ill. The wind farm's medic responded to the emergency call and attended to the patient until the coastguard arrived

-     In recognition of the additional risks relating to major, non-standard works on offshore wind projects, 24-hour enhanced safety supervision has been put in place for the ongoing Merkur blade protection work

-     Safety drills and emergency response exercises were undertaken at several assets both and on and offshore, with bad weather days used as opportunities for further training and familiarisation with vessel cranes, lifting procedures, use of gangways and fire and first aid procedures

Enhancements

As Operations Manager, RES is dedicated to enhancing the operational performance to increase the shareholder and stakeholder value of the portfolio through both commercial and technical initiatives. RES applies a structured framework to identify, appraise and implement enhancements at both the individual project and portfolio levels.

Enhancements secured during the first half of 2023 included:

Commercial enhancements:

-     TRIG entered into a corporate Power Purchase Agreement at Blary Hill onshore wind farm for a ten-year period on pay-as-produced terms. This provides TRIG with long-term price security and improves value on a risk-adjusted basis.

-     Two GB Solar sites qualified for UKPN Flexibility Regime, to enable voluntary compensated curtailment at times of excess generation relative to demand.

-     A significant reduction in the cost of a core operations maintenance contract for an offshore wind farm was achieved following extensive negotiations alongside investment partners, improving upon the investment case. There were no material changes to contract scope.

-     A framework agreement for inverter spares has been signed across eight GB solar projects that will reduce downtime for long-lead time items and enables TRIG to leverage the portfolio effect. Avoided downtime estimated at £500k over the 15-year contract term.

-     FID reached for the installation of additional battery storage at a hybrid solar and battery project within the Phoenix portfolio. TRIG provided financing through the addition of a follow-on loan.

Blade improvements:

-     Following trials at two GB wind farms of aerodynamic improvements to turbine blades, a package is being rolled out across four more sites in the GB wind portfolio, totalling 59MW of generation capacity. The package also includes a suite of software upgrades to maximise the additional energy yield gained from equipment installations and will be initially implemented at one of the trial sites with the upgrades already installed.

-     Across the wider portfolio, application is being investigated, with technical due diligence for aerodynamic blade upgrades being progressed at two joint venture projects.

Wind turbine software enhancements:

-     The wake steering and collective control trial at Altahullion in Northern Ireland has been completed, with testing concluded on three of the four elements. This enhancement is an innovative retrofitted upgrade to increase production and reduce turbine loads. The reduction in loads has been verified by an independent assessment demonstrating an increase in the remaining life of turbine components.

-     Validation of a suite of yield-enhancing software upgrades at Garreg Lwyd wind farm in Wales has been completed following implementation in 2021, confirming a >1% increase in the energy yield.

-     Results from implementation of a pitch and yaw optimization tool at Gode demonstrated an 0.2% yield uplift.

-     Life extension work also continues across TRIG's onshore wind and solar projects in the UK and Ireland. Key milestones in the period include extensions to planning consents at Meikle Carewe and Earlseat onshore wind farms.
