Powering the renewable energy transition

Gresham House Energy Storage Fund plc (LSE: GRID) is the UK’s largest fund investing in utility-scale battery energy storage systems, known as BESS.

GRID invests in a diversified portfolio of BESS projects across Great Britain and can also invest internationally. It seeks to provide shareholders with an attractive and sustainable dividend over the long term, alongside the prospect of capital growth.

As an established market leader in BESS in the UK, GRID currently operates in excess of 1GW of storage capacity.

Why invest in battery energy storage?

The UK’s approach to electricity generation is undergoing fundamental change, shifting from reliance on fossil fuels towards an energy mix dominated by renewable energy.

Energy storage is a cost-effective solution to the intermittency of renewables, addressing supply-demand imbalances on the national grid, in real time.

Investment approach

The investment team have constructed a diversified portfolio of operational utility-scale BESS projects. Each project can generate multiple revenue streams to allow GRID to deliver on its return objectives.
GRID optimises it assets through allocating capacity across the available revenue sources, primarily by balancing between trading and frequency response based on market drivers.

There are three main categories of revenues for BESS in most geographic jurisdictions, each with different rules, pricing, and local terminology:

  • Trading – asset-backed buying and selling of power through wholesale markets and system operator balancing mechanisms.
  • Ancillary services – mostly Frequency Response today, this is the provision of a dynamic response to small supply-demand imbalances, second by second, to maintain the constant electrical frequency required on the GB grid. The largest of these services in GB is Dynamic Containment.
  • Capacity Market – a mechanism whereby generators (including batteries) enter into long-term contractual arrangements to provide capacity to the system when there is the greatest need. This is typically a fixed fee paid to be available and often requires no action day to day.

Key risks

  • The value of the Fund and the income from it is not guaranteed and may fall as well as rise. As your capital is at risk you may get back less than you originally invested
  • Past performance is not a reliable indicator of future performance
