Dover Combined Cycle

Dover Combined Cycle (Cricket Valley)-Advanced Power Services

From Alert--NY Regulators approve 1,000 MW Cricket Valley Energy Power Plant

The New York State Public Service Commission approved a proposed 1,000 MW natural gas-fired power plant February 13. Cricket Valley Energy Center LLC, an affiliate of Advanced Power AG, will construct the combined cycle power plant. Cricket Valley Energy and GE Energy LLC have entered into a joint development agreement to develop the facility. GE will supply 7FA gas turbine technology and the steam turbines for the project. Construction of the power plant could potentially begin in 2014.

Cricket Valley will use air-cooling

http://www.cricketvalley.com/home.aspx

from Cricket Valley website--CVE’s design incorporates air-cooling technology to reduce water use by more than 98%, with a rooftop rainfall capture system to provide a supplemental supply of water and a stormwater management plan that controls rainfall run off with a natural filtration system. CVE will use, on average, about 15 gallons of water per minute during cooler months and up to 60 gallons per minute during the hotter summer months. By way of comparison, a garden hose uses an average of 5 to 10 gallons per minute.

No process water will be discharged into the Swamp River and CVE has incorporated stormwater management techniques to minimize impact on the flow of the River. Wells drilled on the CVE site into the bedrock aquifer have produced sufficient water to meet the needs of the facility and have been tested to ensure that impacts to neighboring wells, the surface aquifer, the Swamp River and associated wetlands are insignificant. A full discussion of CVE water use and an analysis of the well tests are available in Section 5 and Appendix 5-E of the DEIS.

Environmental Impact Statement for Cricket Valley

1.3.5 Facility Overview

The CVE facility will generate approximately 1,000 MW of electricity, fueled only by natural gas. The CVE facility will use “combined cycle” generation technology, one of the most efficient technologies for producing electricity. The facility (Figure 1-5 and 1-6) will be comprised of three combined cycle units, each consisting of a combustion turbine generator, a Heat Recovery Steam Generator (HRSG) with supplemental duct firing, and a steam turbine generator. An updated rendering of the proposed facility is provided in Figure 1-7.

Auxiliary equipment will include a low nitrogen oxide (NOx) natural gas-fired auxiliary boiler, needed to keep the HRSGs warm during periods of turbine shutdown and to provide sealing steam during startups, and four diesel-fired black-start generators, each with a maximum power rating of 3 MW. The four black-start generators would be used to re-start the facility in the event of a total power loss on the local or regional transmission grid.

The Project will be equipped with state-of-the-art emissions control technology, including dry low-NOx burners and selective catalytic reduction (SCR) technology to control emissions of NOx, and an oxidation catalyst to control carbon monoxide (CO) and volatile organic compounds (VOC) emissions. A continuous emissions monitoring system (CEMS) will be utilized to ensure and document facility compliance with applicable emissions standards.

Water use will be minimized by the use of air cooled condensers. Process water supply will be provided from new on-site bedrock wells. A Zero Liquid Discharge system will recycle and reuse water internally, reducing the need for process water and ensuring that no process wastewater will be discharged. The facility will employ BMPs for stormwater management, which will include a system that reflects existing drainage patterns and incorporates a wet extension detention pond, small bio-retention facilities, and roof top rain capture to maintain peak rates of discharge and minimize the potential for erosion and sedimentation.
