Edison Next has reached an agreement with Iberdrola to acquire its cogeneration assets for slurry treatment, along with an adjacent portfolio of biomethane projects.

The transaction includes five operational plants located in León, Burgos, Huesca and Murcia, with a total installed capacity of 52 megawatts (MW), as well as four biomethane projects under development in nearby areas, with an aggregate production of 340 GWh per year.

Through this operation, Edison Next strengthens its presence in Spain and reinforces its commitment to the energy transition, promoting the circular economy and the use of renewable gases.

This transaction, together with two additional agreements signed in recent weeks, also contributes to consolidating Edison Next’s biomethane portfolio, which already includes two projects under construction scheduled to start operations in 2026; two projects expected to reach Ready-to-Build (RtB) status in the coming months; and more than 15 projects at different stages of development, representing a total production capacity of over 1 TWh per year.

Backed by the know-how of the Edison Group, Edison Next combines expertise in circular economy, sustainable water management, energy recovery, and biomethane and biogenic CO₂ solutions. All of this is delivered through an integrated approach focused on energy efficiency, renewables and decarbonization services, which has enabled the company to save more than 2,450 GWh of energy, avoid over 120,000 tonnes of CO₂ emissions, and deliver more than 2,500 projects across industry, the tertiary sector and public administration.
