Engineering, procurement and construction (EPC) contracts are evolving as utilities seek to spread risks, contain costs, and execute their business strategies. As a result, turnkey contractors are...
additional temporary storage to continue plant operation past 2015. AEP says Cook produces the lowest fuel-cost electricity its generating fleet.
Alliant subsidiary Interstate Power and Light (IPL), along with co-owner MidAmerican Energy , started construction on a $345 million emissions reduction technology project at the 726-MW Ottumwa Generating Station, near Chillicothe, Iowa. The addition of a dry scrubber and baghouse systems is designed to reduce sulfur dioxide and mercury emissions by 90 percent to comply with state and federal requirements.
Suntech Power Holdings began selling a new 305-watt solar module for commercial and utility-scale solar projects in North and South America. Suntech says the Ve-Series module includes 72 multicrystalline cells producing 15.5-percent module efficiency, and is certified to withstand loads from extreme wind (3,800 Pascal) or snow (5,400 Pascal). Also, 1000V certification from Underwriters Laboratories means the modules can be safely connected in longer string series than allowed by the earlier 600V industry standard, allowing for larger-scale designs that should reduce balance of system costs such as inverters, wiring, and combiner boxes.
DR & Conservation
Ameresco completed building an energy savings performance project with Ohio’s Cloverleaf School District. The $1.2 million project, which included energy efficient infrastructure upgrades at four facilities, is expected to help the district save over $102,000 in energy, both electric and natural gas usage, and operational costs annually for the duration of a 15-year contract.
Bonneville Power Administration (BPA) and Cowlitz County Public Power Utility District are collaborating with Weyerhaeuser, and Nippon Paper Industries at the North Pacific Paper (NORPAC) paper mill facility on the largest industrial energy efficiency project in BPA history. The chip pre-treatment project, funded jointly by BPA ($21 million) and Cowlitz ($3.9 million), will introduce new industrial processes that aim to reduce electricity and chemicals used in the paper milling process. The money contributed by both BPA and Cowlitz comes from their respective conservation funds, which provide financial incentives to their customers for the development and installation of electrical energy savings projects. NORPAC will fund the remaining $35 million of the $60 million project.
DTE Energy , Enbridge, and Spectra Energy executed a memorandum of understanding (MOU) to jointly develop the NEXUS gas transmission system, a project that will move Ohio Utica shale gas to markets in the Midwest and Ontario, Canada. The proposed project includes about 250 miles of large-diameter pipe, for a 1 Bcf per day capacity. The line will follow existing utility corridors to interconnect in Michigan, where DTE and Enbridge’s existing Vector pipeline system continues to the Ontario market. Upon completing the project, Spectra Energy is expected to become a 20-percent owner in Vector pipeline. The project would interconnect with Michigan Consolidated Gas, Consumers Energy and, through the Vector Pipeline, the Enbridge Tecumseh Gas Storage facility and the Union Gas Dawn Hub, both in Ontario. An open season for the project is planned for fourth quarter 2012, with startup expected as early as November 2015, depending on final market demand and commitments.
Dominion Transmission , the natural gas pipeline subsidiary of Dominion Resources, placed its Appalachian Gateway
