Mexican Power Customer Chooses MAN Again

CFE places order for 5th two-stroke engine at same power plant

Posted on June 25, 2014

The Mexican state-owned electric utility Comisión Federal de Electricidad (CFE) has awarded Spanish contractor, Acciona – the engineering and construction conglomerate – the turnkey contract for the extension of a diesel power plant at La Paz, Baja California Sur, Mexico.

The contract covers the installation of an MAN B&W 12K80MC-S9 engine at the plant, and MAN said that this will be the fifth two-stroke MAN B&W unit to be installed at the Baja California Sur plant.

CFE’s La Paz plant currently has a single 10K90MC-S and three 12K80MC-S engines, providing a combined output of 172.5 MW. At 47.88 MW, the 12K80MC-S9 version’s output will be 5 MW higher than its 12K80MC-S predecessor, while also possessing a lower heat rate, the company said.

The 12K80MC-S9 plant will run on local, cost-effective fuel with a viscosity of around 1200 cSt at 50˚C and 4.3% sulfur content. MAN said the four existing engines already operate successfully on the same fuel and fulfill all local environmental regulations. As with the previous installations, the La Paz power plant will feature both a bottoming cycle steam turbine for utilization of waste heat for power generation and a high-pressure selective catalytic reduction (SCR) for emissions control, the company said.

MAN Diesel & Turbo’s Korean licensee, Doosan Engine, will construct the new engine.
