In July 2013, Caithness Long Island II was selected by LIPA as the best project to meet the Authority’s capacity and energy requirements, while providing maximum value to its customers and protecting the environment. The decision was made after an in-depth analysis of 45 projects submitted by 16 entities responding to a highly competitive request for proposal.
LIPA’s evaluation looked at the attributes of all the proposals, including operational flexibility, environmental impact, interaction with other power-supply resources, and the ability to get the project developed on time.
The proposed Caithness Long Island II 750-MW, natural-gas fired plant was chosen, in part, for its ability to provide LIPA with enough extra capacity to allow for the retirement and/or repowering of older, inefficient plants, while helping it meet its projected need for larger capacity. Caithness Long Island II will greatly contribute to improving the region’s air quality by producing substantially fewer emissions than the decades-old plants LIPA currently uses.
In its decision, LIPA also cited Caithness’s record as a proven, reliable developer, as well as the strong community support it received for its first Long Island plant.
Caithness Long Island II will undergo an extensive and rigorous environmental review and permit procedure, at which time the public’s input will be solicited. Most of the review and permit processes will take place in 2014/15. Construction is expected to take approximately 28 months. Commercial operations are projected to commence in 2018.
- Caithness Long Island II will be built on 24-acres of an 83-acre parcel in an industrially-zoned area in the Town of Brookhaven, Long Island.
- The project site is adjacent to the existing 350-MW Caithness Long Island Energy Center.
- The property is in proximity to existing natural gas supplies and a LIPA-owned electrical-distribution substation.
- The plant will be a 750-MW combined-cycle generating station fueled by clean-burning, economical natural gas, with backup capability to run on ultra-low sulfur distillate when needed.
- The nearest residential housing units are about one third mile away, by contrast most power plants on Long Island have residences at their property lines.
- As with the existing Caithness Long Island Energy Center, the new plant will use innovative air-cooled technology, which means that billions of gallons of drinking water from Long Island’s aquifers will be preserved.
