Felton power plant begins a 21-day overhaul with its unit 1 running at 110 MW

The Lidio Ramón Pérez thermal power plant in Mayarí, Holguín, began a 21-day overhaul on November 10 covering the boiler, the condenser and both regenerative air heaters, according to the plant's acting director, speaking to Prensa Latina. Its unit 1, with a capacity of 260 MW, had been running at about 110.

The work is being carried out by crews from the Power Plant Maintenance Company (ENCE), from Industrial Works Construction Company No. 9 and by the plant's own operators, among others, according to the facility's acting director, Víctor Hugo González, speaking to Prensa Latina.

The most complex task is the full washing of the boiler, which has run for 14 months without that procedure and will require some 15 days of sustained work. The programme also includes cleaning the condenser and replacing the baskets in both regenerative air heaters, considered the critical path because of the volume of dismantling and replacement involved. A further 160 outstanding technical reports are due to be resolved.

Felton's unit one has a capacity of 260 megawatts but ran in recent weeks at about 110, «which shows how necessary the repair is for the national power system», according to Cubadebate.

Diario de Cuba, whose headline says the boiler «can take no more», reported warnings that «a collapse of the national grid is coming» because one of the country's largest thermal plants will be out of service for nearly a month.
