Madrid-based independent power producer (IPP) Matrix Renewables, backed by TPG Rise, has submitted environmental impact and administrative permit applications for two stand-alone lithium-ion battery energy storage systems (BESS) – Visenta and Perdiguero – in Huesca province, Spain.

Located across the municipalities of Sesué, Benasque, and Sahún in the Pyrenees, each project will have a 100 MW grid connection capacity and approximately 400 MWh of storage, enabling four hours of full-power discharge. The combined usable capacity of both facilities totals 407.264 MWh.

Each installation will feature 104 Tesla Megapack 2 XL containers, arranged into 52 double blocks, paired with 26 transformers. Inverters will deliver 0.979 MW AC per unit, with power transmitted via a 30 kV underground medium-voltage network using RHZ1-OL 18/30 kV conductors.

The projects will also include a Pirineo 220/30 kV step-up substation equipped with two transformers rated at 115/220 MVA and 180/185 MVA. The construction budget for each plant is estimated at €62 million.

Matrix Renewables holds a diversified global portfolio spanning renewable energy, battery storage, and green hydrogen. As of 2024, its pipeline totaled 15.5 GW across Europe, Latin America, and North America. In Chile alone, the company has 52 projects amounting to 412 MW.

The company has also been expanding its energy storage footprint, most recently proposing a 1 GW / 2 GWh BESS project in Scotland.
