Unionville oil-based units add to diversity of fuels used to generate electricity

Unionville Power Plant

Unionville Power Plant is comprised of two 1977 General Electric, 22.5-megawatt, simple-cycle, oil-based units with a total peaking capacity of 45 megawatts.

The plant was built to meet the need for peaking capacity, and combustion turbines are well suited for that purpose because they can be started and stopped quickly to meet peak energy demands. The Unionville plant site was chosen in the 1970s because AECI lacked a transmission line to the area, and the installation of a small generating station allowed AECI to defer a big transmission line into the area until 1995 when it built the 161-kV, 33-mile line from Hickory Creek to Locust to serve the area (AECI's history book “Win-Win.”) Today, the Unionville Power Plant's oil units add fuel diversity to AECI's gas- and coal-based generating resources and help meet members' peak demand needs.
