Ilo power station

From Global Energy Monitor


Ilo power station is a multi-fuel power station in the department of Moquegua, Peru. Its coal-fired Ilo 21 power plant has a generating capacity of 135 megawatts (MW); the adjacent dual-fuel Ilo 31 and Ilo 41 plants have a combined capacity of 1110 megawatts (MW).[1]

The plant's original coal-fired power plant, referred to as Central Termoeléctrica Ilo21 in Engie's corporate reports, went online in August 2000 with a capacity of 135 MW.[1][2]

A second 500 MW power plant known as Ilo 31 Cold Reserve was commissioned in 2013. Its three units are equipped to run on diesel or natural gas.[1][3]

Another three-unit, 610 MW power plant known as Nodo Energético Ilo 41 or NEPI (Nodo Energético Proyecto Ilo) was commissioned in 2016, with the same dual-fuel capability as Ilo 31.[1][3]

The Ilo 31 and Ilo 41 power plants are both currently burning diesel, but Engie's plans call for them to convert to natural gas upon completion of the long-planned Southern Gas Pipeline.[4]

Planned Retirement of Ilo 21 coal plant, Unit 1

In December 2019 Engie announced that the Ilo 21 coal plant would close by December 2022 as part of the company's broader decarbonization strategy.[5][6] Engie Latin America's CEO Frank Demaille confirmed the plant's impending closure in a letter to shareholders that appeared in Engie's 2019 annual report, released in March 2020.[1]

Cancellation of proposed Ilo 21 coal plant, Unit 2

A proposed 135 MW coal-fired Unit 2 for the Ilo 2 plant was still listed in Platts' World Electric Power Plants Database[7] as of June 2015 but appears to have been abandoned since it has not been mentioned in company reports or other news sources for more than four years.[1]
