Compostilla power station

From Global Energy Monitor

Compostilla power station is a retired 1,341-megawatt (MW) coal-fired power station in El Bierzo, León, the province of Castilla y León, Spain.[1]

The Compostilla power station was originally commissioned in 1961 to provide electricity to the province of Castilla y León. Several larger units were added in the following two decades. Coal for the plant is sourced from the basins of El Bierzo, Villablino, and Laciana, as well as imported from abroad.[1][2] Water to cool the plant is sourced from the Barcena Reservoir.[1]

In the 2000s, the plant was equipped with desulfurization and denitrification technologies. Units four and five were fitted with flue gas desulphurisation (FGD) systems from 2005 to 2008.[2] However, in 2009, the plant still emitted 2.64 million tonnes of CO2.

In 2008, the original 141MW unit was closed. This was followed by the shutdown of Unit 2 in 2016.[2]

In December 2018, the plant's operator and sponsor, Endesa, petitioned the government to shut down the remaining units, as tightened emissions regulations, the investment required for environmental upgrades, and increased carbon emissions prices made the plant unprofitable.[3][4] The plant was allowed to close on June 30, 2020, along with six others of the fifteen coal plants in Spain. Compostilla produced no energy in 2020 (before the closure) due to the Covid pandemic.[3]

NS Energy Business previously reported that Endesa was planning to construct 300 MW of solar power projects, along with a 20 MW wind farm (representing a total investment of 260 million Euros).[2] However, according to Endesa's more-recently updated website, they are currently planning to develop up to 700 MW of renewable projects near the now-retired Compostilla plant to make up for lost capacity. They estimate a total investment of 600 million Euros. They also say that dismantling the plant will take up to five years (and generate 1,000 jobs per year), thus reducing the economic impacts of the closure in the area. In line with this goal, they are also promoting professional training for workers to help them transition to the renewable energy sector.[5]
