Overview
At its 583 megawatts (MW) combined cycle plant in Johnson, Rhode Island, the Rhode Island State Energy Center faced operational issues when it encountered rotor vibration and other aging steam turbine concerns.
GE Vernova provided an Advanced Steam Path (ASP) upgrade for the site’s D-11 steam turbine. This solution could be installed within a routine outage, allowing the plant to return to operation without any additional downtime. As part of the project the plant became one of the first units of its kind remotely monitored by GE Vernova’s Monitoring & Diagnostics (M&D) Center, allowing the site to foresee any arising issues.
Outcomes
average yearly revenue increase
increased output
GE’s advanced technology increased the plant’s overall output capacity by about 26 megawatts (MW)—which will allow the site to increase average revenue by more than $4 million per year over the next five years.
