Farmington-based Carrier Corp. won an extra $22.4 million contract to boost energy and environmental efficiency at facilities operated by the Alabama Department of Corrections, nearly doubling the value of the original pact.
Carrier’s Noresco unit, based in Westborough, Mass., was granted two new contract phases to design, build and oversee energy and environmental projects. Carrier is a subidiary of United Technologies Corp. in Hartford.
Noresco has a 20-year contract.
The original $27.2 million contract in 2010 between Noresco and Alabama corrections included more than $11 million in funding from the American Recovery and Reinvestment Act of 2009 for, among other things, central plant upgrades, mechanical upgrades, lighting upgrades and water conservation improvements.
Energy savings from work performed under Phase 1 of the contract are intended to finance subsequent phases, authorities said.
Phase 2 will include improvements that include heating, ventilation and air conditioning upgrades, new domestic hot water systems and new roofs at selected locations.
Phase 3 centers on improvements to buildings on the women’s minimum-security campus in Wetumpka, Ala., that Alabama corrections previously acquired from the Alabama Board of Pardons and Parole. The Phase 3 project will decentralize heating and cooling systems, improve water conservation and upgrade lighting.
