Repsol has kicked off construction on the first of two wind farms of the 860 megawatt Delta 2 cluster in the north-eastern Spanish region of Aragon.

The complete Delta 2 is slated to be completed in 2023, when it will supply electricity to aabout 800,000 homes, avoiding the emission of more than 2.6 million tons of carbon dioxide per year.

As part of it strategic plan to reach net-zero emissions by 2050, Repsol plans to reach 7.5 gigawatts of what it calls low-emission generation by 2025, and to double that figure by 2030. Although it includes gas-fired generation in its low-emission category, most of the projects will be from renewable sources.

Repsol currently has 3.3 GW of low-emission generation capacity, including the 335 MW Delta 1 wind power project, also in Aragon, which has been operational since last March with 89 turbines spinning across eight wind farms.

Repsol is currently also building the 175 MW Pi wind project in northern Spain and is developing three solar projects in the country with a combined capacity of 264 MW.

The company last year also began the international expansion of its renewable business, with the signing of a joint venture with Grupo Ibereolica Renovables that gives it access to a portfolio of assets in Chile, that are anticipated to have a combined capacity of more than 1.6 GW by 2025.

Repsol has earmarked €5.5 billion ($6.7 billion), or 30% of its investments foreseen in 2021-25, to low-carbon initiatives.

The company has begun construction of the Cometa 1 and 2 onshore wind projects in the Spanish province of Zaragoza that have a combined capacity of 60 MW, and will begin work on three more wind farms this year that form part of the Delta 2 complex.
