"This project has the potential to create hundreds of construction jobs and provide support for the development of a vibrant renewable energy business - and additional 'green energy' jobs - in Ohio," said Ohio Governor Ted Strickland. "This is an example of how we can leverage technology and our natural resources to grow our economy and ensure our energy future."

Similar to pumped-hydro storage - where water is pumped up to a reservoir then released through a turbine to produce electricity during peak periods - compressed-air technology involves compressing air in an underground cavern or other chamber during the evening - when electricity demand is lower - and releasing it during the day, when the need for electricity is greater.

"A compressed-air energy storage project of this size has the potential to be a major step in advancing electricity storage and balancing load demand," said Arshad Mansoor, vice president of Power Delivery and Utilization at the Electric Power Research Institute. "This could be a key component in integrating large-scale intermittent renewables onto the nation's grid system."

The company is evaluating its options related to the project, but has not yet committed to development scope or timing. However, an initial phase could involve installing two to four units capable of generating a minimum of 268 megawatts (MW) of electricity. With 9.6 million cubic meters of storage, the Norton Energy Storage Project has the potential to be expanded to up to 2,700 MW of capacity.

Currently, there are two commercial-scale compressed air electric generating facilities: a 110 MW plant in McIntosh, Ala., operated by PowerSouth Cooperative that began service in 1991; and a 290 MW facility in Bremen, Germany, that has been in operation since 1978. While there are other compressed-air projects under development, none is expected to be comparable in size and scope to the Norton facility.

The Norton Energy Storage Project is part of FirstEnergy's overall environmental strategy, which includes continued investment in renewable and low-emitting energy resources. In April, the company said it plans to repower units 4 and 5 at its R.E. Burger Plant in Shadyside, Ohio, to generate electricity principally with biomass. And, in September, the company announced plans to complete construction on the Fremont Energy Center, a 707-MW natural-gas-fired peaking plant located in Fremont, Ohio, by the end of 2010. Together, these projects would further reduce the company's average carbon-dioxide emission rate, which already is about one-third below the regional average.

Compressed-air storage, when combined with renewable energy resources, provides for low-emitting power generation that is dispatched when customers need it. FirstEnergy currently has more than 800 MW of renewable capacity, including pumped-storage hydro and wind power. By the end of 2012, when the biomass project at the Burger Plant is complete, the company's renewable capacity could be more than 1,000 MW.

Mr. Strom noted that Haddington leveraged its experience in high-deliverability natural gas storage facilities to become the first private equity fund manager to have invested in, developed and now exited a compressed air energy storage development. "We believe CAES technology will play an important role in providing bulk energy storage services to the nation's electric grid, and we look forward to participating in the development of other new opportunities that utilize CAES," he said.

"The compressed-air technology envisioned at this site would enable us to produce energy that essentially can be stored and used at another time," said Gary R. Leidich, FirstEnergy executive vice president and president of FirstEnergy Generation. "Many renewable energy sources - such as wind - are intermittent and not always available when customers need them. The energy storage aspects of this project could complement our region's overall renewable energy efforts because the power can be dispatched when it is needed."

Haddington has obtained all permits necessary to develop more than 2,000 megawatts (MW) of storage in a 2,200-foot-deep inactive mine on a 92-acre site near Norton. Engineering and equipment design and project cost estimates have been completed for the first 268 MW of generation (two modules) and 220 MW of compression, allowing for substantial expansion after the first phase.

CAES allows utilities to use inexpensive and renewable off-peak electricity to compress air and store it in airtight underground caverns to later meet periods of high demand. When electric power demand peaks during the day, the process is reversed, and the compressed air is returned to the surface and combined with a third of the natural gas typically used in gas-fired power generation to produce electricity.

Haddington Ventures, through its private equity funds, generally makes control-oriented investments in companies focused on gathering, separation, processing, treating, compression, storage, and transmission of energy. Haddington principals developed many of the independent high-deliverability natural gas storage facilities in the U.S., experience which has played an integral role in Haddington's CAES development efforts. Haddington is unique in that it is the only midstream energy fund in which all principals have substantial direct operating company experience, both in energy-related acquisitions and in energy infrastructure development.
