GE to upgrade SCE’s 1,054 MW Mountainview Generating Facility

Mountainview Generating Facility -- Southern California Edison (SCE) -- Combined-cycle power plant

GE’s work could boost the combined-cycle station’s output by about 48 MW. Reduced startup times and lower emissions will help balance the growing role of renewable energy on the grid, according to GE and Southern California Edison.

“Our Mountainview station will be much more flexible, enabling it to more quickly respond to the needs of the California ISO system that is highly penetrated with solar power and other renewable sources,” Stuart R. Hemphill, senior vice president of power supply and operational services at SCE, said in a statement. “GE’s solution also gives us a more efficient plant, creating greater value and savings for our customers.”

Mountainview has four 7FA.03 units, two D-11 steam turbines and associated generators in combined cycle. GE will supply six advanced gas path (AGP) sets, including six sets of its Dry Low NOx 2.6+ combustion system, its OpFlex software package and four new unit rotors. GE’s release predicted that the new combustion system will allow SCE to reduce Mountainview’s emissions without the need for additional water in the process.

“We are excited to support SCE’s upgrades to the Mountainview Generating Facility,” Paul McElhinney, president and CEO of GE’s Power Generation Services business, said. “This agreement underscores their confidence in our generation and combustion technologies and capabilities to execute on extremely complex projects while increasing plant availability. With natural gas playing a growing role in power generation around the world, we are committed to helping operators squeeze every megawatt they can out of their existing facilities while also reducing their site emissions and water consumption.”

GE plans to install the technologies at Mountainview beginning in 2016 and complete the project by May 2017. The equipment is expected to be supplied by GE’s gas turbine facility in Greenville, South Carolina.

Mountainview Generating Facility is about 80 miles east of Los Angeles. The SCE facility generates enough power for about 685,000 homes.

Earlier this year, GE also announced upgrades to combined-cycle power projects in Rhode Island and Ontario.
