Gore Street Energy Storage Fund plc (GSF) continues to hold the London Stock Exchange's (LSEG) Green Economy Mark, having maintained the distinction since the Mark’s inception in 2019.

Of the 95 companies and funds recognised in the Green Economy Mark Class of 2026, only 37 have held the Mark continuously since its launch - and GSF is proud to be among them.

The Green Economy Mark helps investors identify listed companies and funds generating at least 50% of their revenues from environmentally beneficial activities, providing greater transparency for those seeking exposure to the growing green economy.

Helping Investors Identify Opportunities in the Green Economy

The Green Economy Mark was established by the London Stock Exchange (LSEG) to help investors identify listed companies and funds with significant exposure to environmentally beneficial activities. By providing an independent, data-driven assessment, the Mark supports greater transparency and helps investors distinguish between stated sustainability ambitions and commercially material environmental activity.

LSEG’s 2026 Green Economy Mark Report highlights key trends shaping the green economy and sustainable investment landscape. Since its introduction, the Green Economy Mark cohort's combined market capitalisation has more than tripled, growing from approximately £55 billion in 2019 to more than £192 billion in 2026. The cohort now attracts over £70 billion in disclosed institutional investment, with international investors representing 61% of that capital.

Enabling the Energy Transition Through Energy Storage

Managed by Gore Street Capital, GSF invests in utility-scale battery energy storage systems (BESS), a critical component of modern energy infrastructure and a key enabler of the renewable energy transition.

As renewable generation continues to increase globally, energy storage provides the flexibility needed to balance supply and demand, support grid stability and maximise the use of renewable power. This infrastructure is becoming increasingly important as electricity systems evolve towards lower-carbon, more decentralised energy networks.

Gore Street Capital manages the full lifecycle of these investments, combining expertise across investment management, engineering, project delivery, asset management and energy trading. From sourcing opportunities and deploying capital to developing, managing and optimising assets, the team works to deliver attractive returns for investors while supporting the transition to a cleaner and more resilient energy system.

Looking Ahead

As electricity systems continue to evolve and renewable generation grows, demand for energy storage is expected to increase further. The ability to store and dispatch power when it is needed will remain essential to creating reliable, flexible and sustainable energy networks.

GSF's continued recognition through the Green Economy Mark reflects both the environmental impact of the assets it invests in and the role it plays in supporting one of the most significant investment and infrastructure transformations of our time.

Angus Gorden Lennox, Chair of Gore Street Energy Storage Fund plc, said:

"We are delighted that Gore Street Energy Storage Fund continues to hold the Green Economy Mark and to be recognised in helping to drive the green economy forward.

The Mark provides investors with greater transparency, helping them identify businesses and funds whose revenues are linked to activities that deliver environmental benefits. As demand for sustainable investment opportunities continues to grow, this recognition provides further validation of the important role energy storage plays in supporting renewable energy and more resilient electricity systems.

We remain committed to delivering long-term value for shareholders while investing in the infrastructure that supports the energy transition."
