Inside Battery Storage: From Investment to Trading
Battery Energy Storage Systems (BESS) are becoming an increasingly important part of the global energy transition. As renewable energy generation grows, so does the need to ensure that electricity is available when and where it is needed.
The challenge is simple.
Renewable energy sources such as solar and wind don’t always generate electricity when demand is highest. The sun doesn’t shine all day and the wind doesn’t always blow, yet homes and businesses still need reliable power around the clock.
Battery storage helps bridge this gap by storing renewable electricity when it is available and releasing it back to the grid when demand increases.
But battery storage is about far more than batteries.
Behind every asset sits an entire ecosystem of expertise. From identifying the right projects to invest in, through procurement and construction, asset management, commercial optimisation and energy trading, multiple specialist teams work together to ensure these assets operate safely, efficiently and profitably throughout their lifetime.
In our latest video, members of the Gore Street Capital provide a high-level introduction to the BESS lifecycle and share what really goes into making these assets work. Featuring insights from Alicja Kowalewska-Montfort (Managing Director, Commercial), John-Michael Cheshire (Managing Director, Investments), Michael Darzi (Project Development Manager), Daniel Sherlock-Burke (Director of Asset Management), Priya Adinamozhi (Commercial Associate), and Alan Smallwood (Principal, Energy Trading).

The Impact of Battery Storage
While the process may seem complex, the impact is clear.
In the 2025/26 financial year, we estimate that the assets we manage have helped avoid more than 15,000 tonnes of CO₂ and stored nearly 57 GWh of renewable electricity – enough to power almost 21,000 homes for a year.1
These results are made possible by the expertise, decisions and collaboration that take place across every stage of the battery storage lifecycle.
