Spanish energy giant Repsol has switched on its largest solar photovoltaic (PV) farm in Spain, with the 264-megawatt Valdesolar project expected to be fully operational by the third quarter of this year.

At full power, Valdesolar, being developed at a cost of €200 million ($235 million), will provide electricity to some 140,000 homes in the province of Badajoz in the west of Spain, saving over 210,000 tons of carbon dioxide emissions a year.

It comes on the heels of the start-up of Repsol’s first PV complex in June, the 126.6MW Kappa development, which is made up of the Perseo Foton 1-3 projects in the Spanish province of Ciudad Real.

Along with Valdesolar and Kappa, Repsol has a third PV project in Spain, the 204MW Sigma development, in the southern province of Cadiz.

In the wind sector, Repsol recently broke ground on the giant 860MW Delta 2 project in the north-eastern region of Aragon, production from which will be dovetailed into that of the operational 335MW Delta 1 development.

The company also has the 175MW PI wind farm under development in the northern Spanish provinces of Palencia and Valladolid.

Repsol aims to reach a net zero emissions by 2050. To achieve that, the company targets to develop 7.5GW of “low-emissions generation” capacity — a definition that includes combined cycle gas turbines — by 2025 and double that by 2030.

In May, the company made its first foray into the US renewables market with the purchase of 40% stake in solar power and battery storage developer Hecate Energy, which currently has portfolio of projects totalling more than 40GW.
