Gresham House said its unaudited NAV per share as of end-2022 was 155.5p (US$1.89), around 33% higher than end-2021 when it stood at 116.86p.

Gore Street meanwhile said its unaudited NAV per share at the end of 2022 was 113.5p. The firm’s financial year runs April-March so it did not provide a year-on-year figure. But, as per its equivalent release from a year ago, the year-end figure of 113.5p is 9.3% higher than 103.9 as of December 31, 2021.

A share issue by Gore Street which raised £150 million (US$182 million) in April 2022, after which interviewed its CEO Alex O’Cinnede, may explain the difference.

In a lengthier update, Gresham House said its funds’ underlying EBITDA grew 20% in 2022 and it expects to reach a total operating capacity of 1GW in 2023. The firm has only invested in battery storage projects Great Britain to-date.

Gore Street meanwhile is diversifying its portfolio into other markets, so far buying projects in Germany and the US. Most recently it acquired a project in California, the biggest battery storage market in the world, buying a 200MW/400MWh project from Avantus.

Both funds saw battery storage projects win contracts in the UK’s recent T-1 Capacity Market auction for 2024/25.
