Researched by Industrial Info Resources (Sugar Land, Texas)--Annual electricity generation from natural gas-fired power plants has increased by double-digit percentages in every major U.S. market region between 2015 and 2019, according to the U.S. Energy Information Administration (EIA), during which time nearly 35 gigawatts (GW) of gas-fired capacity entered service across the country. Every new unit brought online will demand regular maintenance to remain active in the long run. Industrial Info is tracking more than 150 maintenance-related projects that are set to kick off at natural gas-fired power plants across the U.S. in the first quarter, about half of which is attributed to projects in the Southwest and Southeast market regions.

The Tennessee Valley Authority (TVA) (Chattanooga, Tennessee) and Southern Company (NYSE:SO) (Atlanta, Georgia) lead all other power generators with four projects each, mostly in the Southwest and Southeast regions. In Mississippi alone, TVA is preparing for maintenance programs on natural gas-fired, combined-cycle (NGCC) units 1 through 3 at the Magnolia Energy Project in Ashland, which generate about 1,004 megawatts (MW) combined; NGCC units 1 through 3 at the Southaven Generating Station in Southaven, which generate about 801 MW combined; and the 734-MW, NGCC power plant in Ackerman.

TVA also is preparing for a turnaround on units 1 through 8 at the Colbert Combustion Turbines Plant in Tuscumbia, Alabama, which generate 480 MW altogether. For more information, see Industrial Info's project reports on the Magnolia, Southaven, Ackerman and Colbert projects.

Alabama also is home to Southern Company's planned outage on Unit 1 at the E.B. Harris Station in Autaugaville, an NGCC unit that generates 625 MW. Elsewhere in the region, Southern Company is preparing for maintenance on the simple-cycle units 2 and 3 at the Cleveland County Station in Kings Mountain, North Carolina, which together generate 368 MW; the simple-cycle units 3 and 4 at the Dahlberg Power Station in Nicholson, Georgia, which together generate 154 MW; and the 172-MW Unit 2 at the Oleander Merchant Peaking Power Plant in Cocoa, Florida. For more information, see Industrial Info's project reports on the E.B. Harris, Cleveland County, Dahlberg and Oleander projects.

TVA and Southern Company are among the many power generators to ditch coal-fired energy in favor of natural gas, with an emphasis on renewables and storage in the longer term.

Natural gas has been getting the cold shoulder from California for the past few years, as the Golden State has pursued the most aggressive renewable-generation plan in the nation. The city councils for San Jose and Oakland recently approved measures to prohibit natural gas infrastructure in newly constructed buildings, with some limited exceptions, continuing a trend seen in other Bay Area cities such as San Francisco, Berkeley and Menlo Park. Nonetheless, gas-fired plants elsewhere in the state are preparing for major outages.

Southern California Edison Company, a subsidiary of Edison International (NYSE:EIX) (Rosemead, California), is preparing for an outage on Unit 4 at the Mountainview Power Station in Redlands, which generates 543 MW, while San Diego Gas & Electric Company, a subsidiary of Sempra Energy (NYSE:SRE) (San Diego, California), is readying for maintenance on the 540-MW Palomar Energy Center in Escondido. On a smaller scale, the city of Roseville's Electric Utility Department expects to perform an outage on the 164-MW Roseville Energy Park.

All three are NGCC plants, and each outage is expected to begin in March. For more information, see Industrial Info's reports on the Mountainview, Palomar and Roseville projects.

One of the highest-capacity units expected to undergo maintenance next quarter is NAES Corporation's (Issaquah, Washington) Block 2 at the Astoria Energy Center in Astoria, New York. The 645-MW NGCC unit is expected to begin a 45-day outage in mid-to-late March. For more information, see Industrial Info's project report.
