Guantanamo Bay continues to be upgraded although ready and able to receive many more prisoners now, such as this energy savings contract.

On July 24th, the NAVY awarded Siemens Government Technologies Inc., $828,828,020 for firm-fixed-price task order N3943019F9909 under a previously awarded multiple award, indefinite-delivery/indefinite-quantity, energy savings performance contract (DE-AM36-09G29041) at Naval Base Guantanamo Bay. The work to be performed provides for the construction, operations and maintenance of energy conservation measures to improve energy efficiency and reliability, which include heating, ventilation and air conditioning upgrades, lighting upgrades, commercial refrigeration upgrades, distributed generation, renewable energy photovoltaic for both the demand and supply sides, energy storage, power control, supervisory control and data acquisition, water retrofits and wastewater. Work will be performed in Guantanamo Bay, Cuba, and is expected to be completed by April 2043. No funds will be obligated with this award, as private financing obtained by the contractor will be used for the 31-month construction (i.e. implementation) phase of the project.
