Ivyland, PA – Eugene Water & Electric Board (EWEB) awarded a contract to American Governor Company (AGC) to modernize the two Woodward Mechanical Cabinet Actuators at Carmen powerplant. The contract includes equipment, engineering, demolition, installation, and commissioning services.
Founded in 1911, EWEB is Oregon’s largest customer-owned utility and provides electricity and water to more than 86,000 customers in and near Eugene, Oregon. The compact powerplant contains two 40MW vertical Francis units and discharges water into the McKenzie River, a treasured source of water and recreation for the region. EWEB is governed by a five-member Board of Commissioners, who are elected by the citizens of Eugene and have full control over Eugene’s water and electric utilities. EWEB was the first public utility in Oregon to own a wind farm, and the utility has contracts to purchase a substantial amount of wind and geothermal power generated in the Northwest.
EWEB’s progressive Integrated Electric Resource Plan provides a road map for future decisions. The current plan, developed with the help of citizens, sets two priorities: “Continue an aggressive energy conservation effort, then acquire renewable power to meet any increase in demand that cannot be offset by conservation efforts EWEB’s renewable energy programs include EWEB Greenpower and a solar electric program.”
The two Woodward mechanical governors at Carmen powerhouse, located 75 miles east of Eugene, have operated reliably since they were commissioned 1963, and AGC has supported EWEB with spare parts, field service, and XX pump overhauls for 20 years. EWEB elected to convert these to digital control to better coordinate the power delivery from this renewable generation asset with the variable-renewable electricity generated by EWEB’s portfolio of contracted wind and geothermal assets and thus live up to their commitment “to providing our customers with reliable, cost-effective sources of electricity that have minimal impact on the environment.”
The scope of the governor modernization project includes Governor PLC control enclosure, ElectroHydraulic Interface (EHI), and redundant electronic speed and position feedback devices. The existing Woodward Permanent Magnet Generators (PMGs) will be modified to accept proximity probes for creep detection and the mechanical overspeed switch will be retained for fail-safe overspeed protection. Each new control enclosure will be inserted into the existing actuator cabinet, replacing the governor front panel. New sensors will be provided to enable remote monitoring of the existing HPUs and Pressure Tanks.
Field wiring and other plant devices will be re-used as much as possible to minimize demo/install time. This is a turnkey project requiring an Oregon Contractor’s License, and AGC intends use a licensed subcontractor to perform some or all of the demolition and installation work, under the supervision of our Site Supervisor, Steve Sabo.
