Guam - The Guam Power Authority Cabras facility are expected to be back online this weekend, following a month-long routine turbine overhaul.  The overhauls, which the agency conducts every five years, can cost up to $3 million. But because the boilers and turbines were in such good condition, GPA Spokesperson Art Perez estimates the agency may have saved up to $500,000.

"Everything looked good and it showed that the investments we've been making over the past several years have been paying off, investments into water quality, boiler repairs, maintenance. We opened the turbine and found no significant problems," he said.

Perez added that there was no disruption of service during the maintenance.
