Developer studies 2,000-MW Sentinel Mountain
United Power Corp. of Monmouth, Ore., is studying the feasibility of developing the 2,000-MW Sentinel Mountain pumped-storage project on Crab Creek and Moses Lake in Washington.
United Power is conducting the study under terms of a three-year preliminary permit issued by the Federal Energy Regulatory Commission. The permit expires March 31, 2010.
Sentinel Mountain would include two new dams, an upper and lower reservoir, and two powerhouses containing four units. The project would be expected to generate about 2,628 gigawatt-hours annually, for sale to a local utility.
Washington utility district proposes 84-MW Shanker’s Bend
Okanogan County Public Utility District is pursuing plans to develop 84-MW Shanker’s Bend. Development could include building a 260-foot-tall dam on the Similkameen River.
The district filed a preliminary permit application with the Federal Energy Regulatory Commission proposing to study various options for the water storage and hydro project. Those options include dam heights ranging from 90 to 260 feet. At 260 feet, the dam would be about 1,200 feet long and impound an 18,000-acre reservoir with a storage capacity of 1.7 million acre-feet. About half of the reservoir would be in Canada.
From time to time since 1948, the U.S. Army Corps of Engineers, the International Joint Commission, and the district have studied the project. In the 1980s, the PUD obtained a preliminary permit that subsequently expired.
District prepares application for 8.6-MW Enloe Dam
Okanogan PUD also is preparing a draft license application to restore a small hydroelectric project at Enloe Dam. The 57-foot-tall, 315-foot-long concrete arch gravity dam is located just downstream of Shanker’s Bend.
The district said it anticipates filing the draft application late this year or in early 2008. The site is located 3.5 miles northwest of Oroville, Wash. The 8.6-MW project would feature new construction on a river bank upstream of Similkameen Falls.
Developer renews plan for Mount Hope pumped-storage
The former licensee for the 2,000-MW Mount Hope pumped-storage project renewed plans to develop the project at an inactive mine in New Jersey, but on a smaller scale.
Mt. Hope Waterpower Project LP filed a new application with the Federal Energy Regulatory Commission (FERC), asking for a preliminary permit to study a 1,000-MW project. FERC issued notice of the application in April.
Mount Hope proposes to use water from the Mt. Hope Mine Complex in Rockaway Township of Morris County, N.J. The project would consist of four 250-MW developments, each with a powerhouse and an upper and lower reservoir.
The applicant said the project would be built in four stages. Each powerhouse would feature one reversible pump-turbine. Once all stages are complete, the project would be expected to generate up to 2,080 gigawatt-hours annually.
FERC rescinded a license for the original project in 2005, saying construction did not begin in a timely manner.
Utility pursues development for 30.2-MW Cle Elum
Grant County Public Utility District said it plans to apply for a Federal Energy Regulatory Commission (FERC) license to construct and operate the 30.2-MW Cle Elum hydroelectric project in Washington.
The new power plant would be built at an earthfill dam operated by the U.S. Department of the Interior’s Bureau of Reclamation on the Cle Elum River 10 miles northwest of Cle Elum.
FERC granted the district a three-year preliminary permit to study the project in January. The permit expires at the end of December 2009.
Hydro Green Energy studies four Mississippi projects
Hydro Green Energy LLC is investigating development of four hydropower projects in Mississippi that would use a combination of conventional and hydrokinetic technologies to generate more than 96 MW.

Hydro Green Energy designs, builds, and operates hydrokinetic energy systems that can be deployed in rivers, tidal areas, and oceans. The systems generate electricity from moving water without a need to construct dams, impoundments, or conduits.
Corps rehab project boosts Hartwell capacity to 422 MW
The U.S. Army Corps of Engineers completed a $33 million refurbishment of the Hartwell project on the Savannah River in Georgia. The refurbishment increased the facility’s capacity 78 MW to a total of 422 MW.
Congress provided initial funding for the refurbishment and upgrade in 1995, with on-site work beginning in 1997.
Four of Hartwell’s five generators were refurbished, increasing the output of each to 85.5 MW from 66 MW; a fifth generator rated at 80 MW did not require refurbishment. Turbine work also was included in the upgrade.
In addition to the generator rewinding, electrical and mechanical peripheral equipment was replaced. Generator circuit breakers, mechanical governor controls, exciters, and switchyard circuit breakers were replaced. As for the turbines, weld cracks and cavitation damage to runners were addressed. Lead-based paint in the turbine scroll case area was removed. New head gates, draft tube gates, and stop logs were fabricated, and an oil-water separator was installed for environmental compliance.
The Corps said National Electric Coil rewound the generators and was prime contractor for refurbishing the turbines. East Coast Management Inc. was a subcontractor to National Electric Coil for turbine work.
Other contractors included: ABB, transformer and generator breaker supply; J.L. Malone, installation of transformers and generator breakers; NESI and Areva, switchyard breaker supply; and Webb Erection Inc., switchyard upgrade. Cutler Hammer and Maddux Supply Co. provided and installed exciters. Voith Siemens handled governor replacement. The Tennessee Valley Authority provided new head gates, draft tube gates, and stop logs.
California approves purchase of renewables by PG&E

The contract was secured under PG&E’s renewable energy procurement program to meet the requirements of the state’s renewables portfolio standard. The renewables portfolio standard law requires 20 percent of investor-owned utilities’ power to come from renewable sources by 2010.
With the contract in place, Georgetown Divide Public Utility District will reactivate the project. The project consists of two developments: 600-kW Tunnel Hill and 400-kW Buckeye. Developer Henwood Associates Inc. is to reinstall equipment.
New York restarts Unit 2 of 1,160-MW Blenheim-Gilboa
The New York Power Authority (NYPA) has returned to service the first unit it overhauled in a modernization program of the 1,160-MW Blenheim-Gilboa Pumped-Storage project.
Unit 2, which restarted over Memorial Day weekend, was the first unit refurbished in a four-year, $135 million program that began in September 2006 to modernize and extend the life of the project.
Initial work on each unit requires that the water level in the project’s upper reservoir be lowered each fall, using cofferdams, to permit replacement of the spherical valves that control the flow of water into the powerhouse. NYPA first shut down all four units in September 2006 to prepare for Unit 2 work, and returned the other units to service two months later.
NYPA plans to shut down Unit 1 for its overhaul in September. As was the case in 2006, the power authority plans to shut the entire station for part of October and November 2007 to lower the water level of the upper reservoir to prepare for work on the unit. NYPA plans to return Unit 1 to service in May 2008.
The modernization schedule calls for similar work on the other two units –- Units 3 and 4 – to be repeated in fall 2008 and 2009. NYPA expects to complete the overhaul program in May 2010.
The overhaul program includes replacement of major mechanical and electrical components, and maintenance and repairs to most other parts. Following overhauls, each unit will have a capacity of 290 MW.
