LEAG Starts Construction of 400 MW / 1.6 GWh Boxberg Battery Storage Project
LEAG Clean Power has started construction of the 400 MW / 1.6 GWh GigaBattery Boxberg 400 project in Saxony, Germany, transforming part of the former Boxberg lignite power complex into large-scale energy-storage infrastructure. The four-hour BESS is being built across a six-hectare remediated site and will use HyperStrong’s HyperBlock III liquid-cooled lithium-iron-phosphate technology. HyperStrong is delivering the system as turnkey contractor, including batteries, electrical integration and construction. Once operational, its 1,600 MWh storage capacity could theoretically supply around 640,000 households for four hours. The project will connect to the 50Hertz transmission system through a new 380-kV substation. Boxberg forms part of LEAG’s broader GigawattFactory strategy for replacing former coal infrastructure with renewables and flexible storage capacity.
Genesis Approves NZD 125 Million Investment in 70 MW Leeston Solar Farm
Genesis Energy has reached final investment decision on the 70 MWp Leeston Solar Farm in Canterbury, committing NZD 125 million, approximately $74 million, to the New Zealand project. Construction can now proceed, with electricity generation expected to begin in 2028. The solar farm will occupy around 111 hectares and use approximately 74,000 photovoltaic panels. Once operational, Leeston is expected to produce roughly 110 GWh of renewable electricity annually, while the landowner can continue sheep grazing around the array. The investment supports Genesis Energy’s strategy to increase its renewable generation portfolio and diversify New Zealand’s electricity mix beyond hydro, geothermal and wind. Leeston follows the company’s involvement in the 63 MWp Lauriston solar farm, which entered operation in 2025.
OCI Energy and Arava Power Start Construction of $394 Million, 347 MW SunRoper Solar Project in Texas
OCI Energy and Arava Power have broken ground on the 347 MWdc SunRoper Solar project in Wharton County, Texas, marking the start of construction on a major ERCOT renewable-energy asset. The project is expected to require approximately $394 million of investment and is being financed by ING Capital, with WHC serving as EPC contractor. SunRoper is backed by a 20-year power purchase agreement with an undisclosed Fortune 100 company. Commercial operation is now targeted for December 2027. Located roughly 60 miles southwest of Houston, the project will supply one of the largest electricity-demand centres in the US. Arava Power has said SunRoper supports its goal of developing more than 1 GW of US solar capacity.
