The Monterey County Office of Education (MCOE) and Chevron Energy Solutions unveiled a solar power and energy efficiency project at the MCOE headquarters in Salinas. Construction began in February 2012. The project is comprised of a 630-kW PV canopy system and public infrastructure improvements, including an energy-efficient hot water boiler, an energy management system to control lighting, and upgraded HVAC and water systems. MCOE secured a solar rebate of nearly $500,000 from PG&E, as well as a federal grant of $881,000 to help offset its costs.
Miami-Dade County awarded an energy performance contract to Ameresco for a comprehensive facility-wide audit of energy and water usage plus recommendations for reducing the county’s $8.6 million annual spending on energy and water utilities in public housing. Upon approval by the county and the U.S. Department of Housing and Urban Development (HUD), Ameresco is expected to manage the design and implementation of retrofits. The HUD energy performance contract program provides incentives to public housing authorities across the country to save energy and water at their housing units.
San Diego Gas & Electric (SDG&E) commissioned the Sunrise Powerlink, a 500,000-volt transmission line connecting San Diego to the Imperial Valley. The $1.9 billion project took 18 months to build, after five years of environmental review and permitting processes. Initially the transmission line will bring up to 800 MW of power into San Diego, and eventually is expected to carry 1,000 MW, including substantial amounts of wind and solar power. The Sunrise Powerlink consists of more than 110 miles of overhead 500-kV and 230-kV transmission towers and conductor, 6.2 miles of underground 230-kV cable, and a 40-acre, 500-kV transmission substation.
Clean Line Energy Partners and the Western Area Power Administration (WAPA) agreed to advance the proposed Centennial West Clean Line transmission project, a 900-mile high-voltage direct-current (HVDC) line to deliver 3,500 MW of renewable power from northeastern New Mexico to communities in California. The project would include an intermediate converter station in Mohave County, Ariz., to access the state’s solar resources. WAPA is expected to serve as a joint lead agency with the federal Bureau of Land Management in conducting environmental reviews. Centennial West will fund environmental compliance work and Western’s review and due diligence. The agreement covers the development period of the proposed project, during which Western and Clean Line will evaluate the project and determine next steps. The agreement is similar to one WAPA entered with Southline Transmission earlier this year, and that Fortnightly reported in the June 2012 Vendor Neutral column.
ABB won a $75 million turnkey contract from the Ministry of Electricity of Iraq to expand an existing transmission substation in the southern part of the country. The 400/132 kV Amara substation will connect to the grid a new 500-MW gas-fired power plant as well as smaller facilities now under construction. The project is scheduled for completion by 2013.
