“Last night’s approval sets the stage for GPA to begin the procurement process to bring online up to 180MW of combined cycle generation which will utilize a cleaner source of fuel, comply with USEPA requirements and deliver reliability and efficiency to our power system,” stated John M. Benavente, P.E., GPA General Manager, “It also allows GPA to pursue and integrate an additional 120MW of renewable energy resources to meet renewable energy standards for Guam.”
The new combined cycle units will be more efficient than existing baseload units and would result in the consumption of less fuel. The site of the proposed new generation will be adjacent to the Guam Waterworks Authority Sewage Treatment Plant and would utilize re-use water to augment cooling requirements for power plant operations.
The main driver for the IRP development is the need for GPA baseload generation units to comply with United States Environmental Protection Agency (USEPA) regulations. Some of the regulations include provisions under the RICE MACT and the EGU MATS rules.
“GPA is well on its path for improving generation reliability with this approval,” remarked Benavente, “With additional work on other units like Dededo Combustion Turbine (CT) 1 & 2 expected to return to service (RTS) in March of 2017, Macheche CT expected to RTS by early November and the major overhaul of our diesel units over the next two years, GPA will be positioned well to provide dependable generation while adding more renewable energy sources to the power grid - I would like to personally express my thanks to the Consolidated Commission on Utilities and PUC for their approval of this monumental decision and thank all the hard working GPA staff for making this achievement a reality.”
