GPA Wants to Fast-Track Approval for Two New Power Plants


The explosion created a large hole in the roof of cabras 3&4. 

Guam – The Guam Power Authority plans to ask the Public Utlities Comission to fast-track tjhe construction of two new combined cycle plants in the midst of the current energy crisis. 


Back on September 9th, GPA General Manager John Benavente presented a list of recommendations to the Consolidated Commission on Utilities on how GPA will handle the lost capacity since the explosions at Cabras 3&4. In an attempt to figure out a short-term solution, Guam Power Authority General Manager John Benavente came up with a plan to ask major consumers of electricity, such as hotels, to go on standby generators to free up electricity during peak hours. Benavente, along with members of the CCU have called this plan short-term, however, one of the long-term plans that Benavente laid out is to petition the Public Utilities Commission to expedite the combined cycle plant.

The plan for GPA to build two new combined cycle plants has been in the works dating back to November of 2104. However, on January 29th of this year the PUC rejected the proposal listing eight ‘anomalies’ within the financial data provided by GPA regarding the proposed plants. The docket states, “for all the previously stated reasons, the analyses that have been provided to the PUC to date have been found lacking in completeness and consistency making it difficult to have confidence in the conclusions reached.”

At the time GPA submitted the petition, the Combined Cycle Plants were presented as an alternative to spending money upgrading existing plants, specifically, $460-million in stack emission equipment to continue to operate Cabras 1&2 which GPA says in the docket are “nearing the end of their useful lives.” Currently Cabras 1&2 are the only remaining generators at the Piti plant as 3&4 are down due to the explosion. The PUC however says in the docket that while GPA says Cabras 1&2 are nearing the end, PUC refers to a 2011 LNG feasibility study that indicates that the life of Cabras 1&2, as well as Tanguisson 1&2 could be extended 25 years at a cost of $2- $3 million dollars a year. Benavente has said that the total loss of capacity from the explosions is 79 megawatts of capacity. The proposed combined cycle plants can generate a possible 120 megawatts with an option for an additional 60 Megawatts.
