Harmony Energy Income Trust plc
(the "Company" or "HEIT")

AGM Trading Update

Harmony Energy Income Trust plc, which invests in battery energy storage system ("BESS") assets in Great Britain, will hold its Annual General Meeting at 10.00 am today at the offices of Berenberg at 60 Threadneedle Street, London, EC2R 8HP. At the meeting, the Investment Adviser will provide a high-level portfolio and operational update for the 11 week period ended 15 April 2024.

Portfolio & Operational update for the period 15 April 2024

·         On 11 March 2024 National Grid ESO launched the Balancing Reserve ancillary service.

·         At the same time, National Grid ESO also amended the "15 minute rule" - a key constraint which had restricted the duration of actions awarded to BESS projects in the Balancing Mechanism.

·        The Investment Adviser previously indicated that these two events would increase opportunities for BESS in the Balancing Mechanism.  Indeed, volumes (in MWh) captured by the Company's portfolio from Balancing Mechanism activities have grown by 313% (January versus March), and the proportion of the Company's monthly revenue derived from Balancing Mechanism has increased from 15% (January) to 34% (April month-to-date).

·     In addition to the above, we have also witnessed increasing wholesale market spreads caused by high   penetration of wind generation in Great Britain during periods of low demand.  This leads to low wholesale market pricing (and even periods of negative pricing) during which BESS has opportunity to be remunerated for importing power and subsequently selling at higher prices.

·     As previously communicated, growing revenue opportunity in the Balancing Mechanism and/or wholesale   markets is advantageous to 2-hour duration BESS, as both markets are priced in £/MWh, rather than £/MW.

·     Like-for-like revenue (including Capacity Market revenue) has improved by c.58% from c.£45,500/MW/Year (January full month) to c.£72,000/MW/Year (April month-to-date):

·           In addition to the above, the Company has recognised additional revenue during February 2024 relating to:

o   the Embedded Export Tariff ("EET") being accounted for in February.  The EET is retrospectively awarded to generating assets in certain zones (in the Midlands and South of Great Britain) which exported power during the three half-hourly periods of highest demand during the winter months (November-February inclusive); and

o   adjustments to prior periods to account for reconciliations of revenue from Elexon and Tesla (in their role as revenue optimiser).

Taking into account these adjustments, the total revenue for February 2024 was £80,800/MW/Year.

The Company will publish further commentary (as well as further updates on the portfolio and an update on its strategy in relation to dividends and other methods of delivering value to Shareholders) in its next quarterly trading and net asset value (as at 30 April 2024) update before the end of May 2024.  Until such time, the dividend policy remains as set out in the recent Annual Report and Accounts.
