These have a combined capacity of 110MW, and have been purchased from green energy investor-developer Arlington Energy and funded by the INFRAGREEN IV fund, which had raised €670 million (US$758.4 million) when it closed in June.

“This first venture in the UK energy storage market reinforces our internationalisation strategy,” said Nicolas Rochon, founder and CEO of RGREEN INVEST.

“RGREEN INVEST’s ambition is to become a recognised European player in this market. The choice of the United Kingdom is significant as the country has identified energy storage as a priority to accelerate its transition to renewable energy sources.”

1 December 2021: UK listed storage fund wins 90MW expansion offer for Ireland project’s grid connection point

Gore Street Energy Storage Fund’s Kilmannock battery energy storage system (BESS) in Co. Wexford, Ireland, has received an additional grid volume allocation of 90MW, building on the 30MW currently secured.

The expansion of the BESS – which is currently under development by the London Stock Exchange-listed energy storage fund – was given a grid connection offer through transmission network groups Eirgrid and ESB Networks’ enduring connection policy (ECP) process last week. This also saw 1,533MW of solar, six hybrid solar-plus-storage sites consisting of 325MW of solar and 441MW of battery storage and another standalone battery storage site receive grid connection offers.

The increased asset capacity of Kilmannock will lower the price per MW of construction, further increasing the price advantage of the asset, Gore Street said.

The company’s portfolio consists of over 600MW of operating and under construction projects in the UK and Ireland as of 19 November 2021, with 310MW of assets across the island of Ireland.

30 November 2021: UK’s first battery storage installation standard launched 

The UK’s Microgeneration Certification Scheme (MCS) has launched what it says is the first battery installation standard, detailing requirements for MCS certified installers who supply, design and install electrical energy storage or battery systems.

Having been piloted at the beginning of 2020 with volunteer installers, the standard (MIS 3012) has been developed with input from the likes of Solar Energy UK, REA, AceOn Group, Tesla, Sonnen, Moixa and Powervault.

It covers installations up to 50kW and Electrical Energy Storage System (EESS) classes 1-4, which are defined as:

  • Class One: all the components are in the same enclosure, or multiple enclosures from the same manufacturer but with no visible direct current (DC) cable
  • Class Two: battery modules and inverter are in separate enclosures linked by a DC cable but both components from the same manufacturer
  • Class Three: the same as class two, but the battery modules and inverter are from different manufacturers, requiring the installer to determine compatibility
  • Class Four: all components, including battery modules, safety devices and inverters, could all be from different manufacturers but are selected and assembled by the installer to be compatible with each other

Registrations under MIS 3012 will sit alongside small scale renewable energy installations currently held within the MCS Installation Database (MID), which includes MCS certification of microgeneration technologies used to produce electricity and heat from low carbon sources, such as solar PV, heat pumps and biomass.
