Inaugurated in May 2016, the 61.5 MW San Isidro plant generates electricity from a mix of biomass and coal. During the November to May sugar cane harvest season, it runs on bagasse (cellulose fiber from crushed sugar cane stalks); from June to October, it runs on coal.[1]

Most of the electricity generated by the plant is used in the neighboring department of Retalhuleu. The plant is equipped with a Japanese Shin Nippon turbine, a British-made Brush generator, and a 220-ton-per-hour John Thompson boiler designed to meet World Bank environmental standards, operating at 540°C with an efficiency of 88.5%.[1]

At the national level Guatemala continues to move away from coal towards renewables. Under the new contracts signed by national electricity agency EEGSA during Guatemala's February 2020 energy tender, plants burning coal only will account for 8% of national electricity production in 2021 (down from 18% in 2019) while plants such as San Isidro that use a mix of coal and biomass will represent 2% of national production in 2021.[2]

Guatemala's power generation planning report for 2020-2034, published by the Guatemalan Ministry of Energy and Mines, does not include the San Isidro power station in its list of coal- and biomass-fired power plants.[3]
