Global energy storage developer Eku Energy has started constructing two UK battery energy storage systems (BESS), totalling 130MWh of capacity.

The two BESS, situated in Basildon, Essex, and Loudwater, Buckinghamshire, will utilise NHOA Energy’s, a developer of turn-key energy storage systems, battery technology marking the company’s entry into the UK market. Eku Energy is a BESS development platform launched in late 2022 by Australian financial services company Macquarie Asset Management’s Green Investment Group (GIG).

The energy storage division of New HOrizons Ahead (NHOA), which also has business lines for e-mobility and electric vehicle (EV) fast charging infrastructure, recorded a 384% growth in online BESS capacity at the end of Q3 2022 to the end of Q3 2023, as reported by Energy-Storage.news.

In an announcement made today (19 February), Eku Energy said it anticipates the BESS projects to be operational by the end of 2024. It is worth noting that Eku Energy already has a 40MW/40MWh battery in Maldon, Essex in construction.

The individual capacity of the BESS projects or output to the grid in megawatts was not disclosed.

The company now has 4.6GWh in development, construction and operation across the UK, Australia, Italy and Japan to deliver 9GWh by 2028.

Sandra Grauers Nilsson, CEO of Eku Energy said: “Breaking ground at Basildon and Loudwater is a major milestone for Eku Energy as we work to support the UK’s decarbonisation goals and expand our global footprint. We have an ambitious pipeline of battery storage projects which we are developing at pace and scale, and we are delighted to have partnered with NHOA Energy to advance the energy transition.”
