Why the Governance Around Gore Street's Irish Disposal Says More Than the Price Would

Gore Street Energy Storage Fund has sold two pre-construction battery projects in the Republic of Ireland, Kilmannock at 120 MW and 240 MWh and Mucklagh at 75 MW and 150 MWh. The buyer is GS EU Fund SCSp, a client of and managed by Gore Street Investment Management, the same manager as the listed fund, though not part of its group. The price was not disclosed, with the fund confirming only that it achieved no less than the most recently published net asset value. These are the first disposals under a strategy announced in March 2026.

What exactly was sold?

Gore Street held 100 percent of Kilmannock across Phase I at 30 MW and Phase II at 90 MW, and 51 percent of Mucklagh, equivalent to 38.25 MW on an ownership-adjusted basis. GS EU now holds 100 percent of both sites, so the transaction covers 195 MW and 390 MWh gross, or roughly 158 MW and 317 MWh attributable to the seller. Both are two-hour systems and both are pre-construction, meaning no revenue has yet been generated. The consideration was withheld on grounds of commercial sensitivity, with the fund stating only that proceeds were no less than carrying value.

Why does a related-party sale need this much process?

Because the manager sits on both sides. Gore Street Investment Management manages both the listed fund selling the assets and the vehicle buying them, which creates an inherent conflict over price: the same firm earning fees from both parties has no obvious commercial incentive to push hard on either side of the negotiation. The announcement describes an unusually elaborate answer to that problem. Strict information barriers separated the teams, an independent third party confirmed valuations for the buyer, the listed fund's board monitored the process, and Alexa Capital was appointed as sell-side adviser to run a competitive, independent bidding process. Each of those steps is standard practice individually. Deploying all of them at once, and describing them at length in a regulatory announcement, indicates how carefully the board expected the transaction to be scrutinised.

Why sell pre-construction assets at all?

Because the fund needs cash for distributions rather than capacity for growth. Gore Street's updated strategy commits proceeds from sales to shareholder distributions and to accretive reinvestment, with FY26/27 targets of £25 million of gross disposal proceeds, around 100 MWh of augmentation or buildout, and 7 pence per share in distributions paid quarterly. Pre-construction assets are the natural candidates to sell first, because they consume capital rather than producing it and their carrying value depends on forecasts rather than on operating history. The alternative use of the same money is visible in the announcement: augmentations at Stony at 79.9 MW and Ferrymuir at 49.9 MW, extending each from one hour to two hours by December 2026, which adds roughly 130 MWh to assets that already earn.

The valuation language deserves attention. Confirming that proceeds were no less than published NAV is meaningful for a listed fund, because it validates the carrying value that determines the share price benchmark. Gore Street has traded at a persistent and substantial discount to its net asset value, in common with most listed renewable infrastructure trusts, and selling assets at NAV to a private vehicle is therefore accretive relative to what public markets ascribe to the same portfolio. It also underlines the structural problem: if the private market will pay carrying value and the public market will not, the logic of remaining listed weakens with every disposal.

What does the deal signal for Irish storage?

The deal signals that Irish battery assets can find buyers at carrying value even before construction, and that ownership is rotating between funds rather than expanding the pool of owners. Enerdatics records only four Irish battery transactions since the start of 2023, and Gore Street features in the earliest of them, acquiring 285 MW from Low Carbon in March 2024. The same fund is now selling 195 MW of pre-construction Irish capacity, while Capital Dynamics has bought two Irish positions this year. That is a market where the same handful of names appear repeatedly on both sides, which is characteristic of a segment with strong fundamentals and shallow participation.

The disposal programme has further to run. Gore Street has two more sales processes ongoing, including the German Cremzow asset which it describes as delayed but at an advanced stage, and a stated target of £25 million in gross proceeds for the year. For a fund that has been an active buyer of Irish and European storage, becoming a net seller of pre-construction capacity to fund distributions is a considerable change of direction, and the coming disposals will show whether the private bid holds at carrying value across the rest of the portfolio.

• Governance measures included strict information barriers, independent third-party valuation for the buyer, board monitoring and a competitive bidding process overseen by Alexa Capital as sell-side adviser.
• Proceeds support FY26/27 targets of £25 million of gross disposals, around 100 MWh of augmentation and 7 pence per share in distributions, alongside augmentations at Stony (79.9 MW) and Ferrymuir (49.9 MW) extending both from one to two hours by December 2026.

Frequently asked questions

How much did Gore Street receive for the Irish battery projects?The value was not disclosed, on grounds of commercial sensitivity. The fund confirmed only that it achieved no less than the values ascribed to the assets in its most recently published net asset value.

Who is GS EU Fund SCSp?GS EU Fund SCSp is a client of and managed by Gore Street Investment Management, the same firm that manages Gore Street Energy Storage Fund, though it is not part of the manager's group. It now holds 100 percent of both the Kilmannock and Mucklagh sites.

What is battery augmentation?Augmentation adds cells to an existing battery installation to increase its energy capacity without changing its power rating, typically extending duration. Gore Street is extending Stony (79.9 MW) and Ferrymuir (49.9 MW) from one hour to two hours, targeted to be fully operational by December 2026.
