FERC final EIS supports licensing 1,300-MW Eagle Mountain
The Federal Energy Regulatory Commission staff has issued a final environmental impact statement recommending licensing of the 1,300-MW Eagle Mountain pumped-storage project, proposed for Riverside County, Calif. FERC staff issued a draft EIS in 2010 supporting issuance of a license to Eagle Crest Energy Co.
Utilizing a head of 1,400 feet between two reservoirs created from abandoned mining pits, Eagle Mountain would be a closed system. Because the site already has sustained significant environmental disturbance, further development for pumped storage would have little additional impact, Eagle Crest said.
The EIS, issued Jan. 30, analyzes the effects of the project as proposed by Eagle Crest, as well as the applicant's proposal plus staff modifications primarily to mitigate environmental effects. It recommends licensing the project as proposed by Eagle Crest with some staff modifications and additional measures.
The primary environmental issues associated with the project are effects of its construction and operation on groundwater, water quality and terrestrial species.
The project includes construction of two saddle dams and liners for the reservoirs. Groundwater is to be pumped from a series of proposed wells in the Chuckwalla Basin to fill the reservoirs and replace water lost to evaporation. A reverse osmosis system is to be installed to remove salts and metals to help maintain water quality of the reservoirs and counteract degradation associated with evaporation.
Construction would employ about 100 during peak construction and provide tax revenues to county and local governments. Operation would provide about 30 jobs and substantial property tax payments.
The project, with staff modifications, would produce power that is $133.1 million, or about $30.90 per MWh, less than the cost of alternative power.

Ludington upgrade one step closer to completion
A US$800 million upgrade to Michigan's Ludington Pumped-Storage Plant reached an important milestone in February after improvements to the Lake Michigan barge dock were completed. Preparations can now begin for the reception of six new, 290-ton turbine runners that will increase the facility's capacity by 300 MW. Currently, the plant has a capacity of 1,872 MW.
The facility is jointly owned by Consumers Energy Company and Detroit Edison Company, who recently completed a comprehensive condition assessment and life extension study to determine how to best upgrade Ludington.
The two then filed to amend their license with the Federal Energy Regulatory Commission earlier this year.
The companies say work on the project should be completed by 2019.
Cherokee Nation seeks funding for hydro project's next phase
A unanimous decision by the Cherokee Nation Tribal Council will allow the tribe to move forward with its proposal to construct a US$144 million powerhouse at the W.D. Mayo Lock and Dam in Oklahoma.
The council's vote authorizes Cherokee Nation Businesses to apply for more than $1 million in grant money from the U.S. Department of the Interior, which would be used to fund the fifth step in the project's development.
The dam, on the Arkansas River, is owned by the U.S. Army Corps of Engineers. Interior's grant would allow engineers to build a model necessary for the Corps to approve construction plans. Additionally, Phase V includes allocations for pre-construction and development, permits, environmental reviews, power purchase agreements, transmission and interconnection.
The plant will be owned by the Cherokee Nation, which holds the exclusive building rights to the Arkansas riverbed.
Plant capacity has not been an-nounced. A tribal council source says the powerhouse is being designed with a 100-year service life and a completion date of 2015.
The project was originally authorized by Congress in 1986 but tabled until 2009 when Interior's Energy and Minerals Development Program (DOI-EMDP) funded Phase I.

Duke, Progress to submit new merger mitigation plan to FERC
Duke Energy and Progress Energy are preparing a new mitigation plan intended to meet Federal Energy Regulatory Commission concerns about a merger that would create the largest utility in the U.S.
FERC rejected the utilities' proposed mitigation plan to remedy what it found to be harmful effects of the merger on utility competition in North and South Carolina. FERC's Dec. 14, 2011, ruling noted the commission already approved the merger, provided Duke and Progress proposed acceptable mitigation measures to protect competition.
The combined company would have about 57,000 MW of generating capacity from hydroelectric, coal, nuclear, natural gas, oil and other renewable generation. It would serve 7.1 million electric customers in North and South Carolina, Florida, Indiana, Kentucky and Ohio.
FERC said the proposed merger would concentrate the utilities' monopoly power to unacceptable levels in the Carolinas. The commission said the utilities' mitigation proposal did not eliminate the opportunity for the merged company to act anti-competitively. Although Duke and Progress described the proposal as a "virtual divestiture" of 225 to 500 MW of capacity in certain seasons, FERC said the plan would not divest control of the energy the applicants proposed to sell.
Duke and Progress said the setback changes the timeline for closure of the merger to March at the earliest. It had been proposed for the end of 2011.
