Linn County Rural Electric Cooperative (Corridor Energy Cooperative)

Linn County REC, doing business as Corridor Energy Cooperative, does not publish an EV-specific rate. Instead, it places residential members on a default 3-tier Time-of-Day rate. Power costs the most on-peak, 4:01pm to 10:00pm, at about 15.7 cents per kWh; it drops to roughly 11.45 cents off-peak, 5:01am to 4:00pm; and it falls to about 5 cents during the Super Saver window, 10:01pm to 5:00am. An EV owner who schedules charging to start after 10pm pays the lowest rate the co-op offers, which makes overnight home charging the clear default here.

The residential Level 2 charger rebate pays 50 percent of the charger and installation cost, up to $175, and the member must own an EV and be on the co-op's Time-of-Day rate to qualify. Because every residential member is already on the Time-of-Day rate, the rebate and the overnight Super Saver pricing work together without any separate enrollment step. Multifamily properties and commercial sites use different programs: multifamily properties with five or more units get $500 per unit (max $2,000 per address), and commercial EV and forklift chargers each pay $1,000 per charger, up to four chargers per category.

As an Iowa electric cooperative, Linn County REC is member-governed and is not rate-regulated by the Iowa Utilities Commission the way the investor-owned utilities are; its board sets rates to reflect wholesale power costs. That is why the whole residential base sits on Time-of-Day pricing rather than a flat rate, and it is distinct from neighboring providers Alliant Energy and MidAmerican Energy. The service territory is rural, covering parts of Benton, Cedar, Iowa, Johnson, Jones, and Linn counties.
