TWEETS

Full retail credit with no subtractions. Customers protected from fees and additional charges. Rules actively encourage use of DG.

A

Generally good net metering policies with full retail credit, but there could be certain fees or costs that detract from full retail equivalent value. There may be some obstacles to net metering.

B

Adequate net metering rules, but there could be some significant fees or other obstacles that undercut the value or make the process of net metering more difficult.

C

Poor net metering policies with substantial charges or other hindrances. Many customers will forgo an opportunity to install DG because net metering rules subtract substantial economic value.

D

Net metering policies that deter customer-sited DG.

System Capacity Limit

500 kW

Aggregate Capacity Limit

No limit specified

Net Excess Generation

Credited to customer's next bill at retail rate; carries over indefinitely

REC Ownership

recommendations

  • Remove system size limitations to allow customers to meet all on-site energy needs Expand net metering to all utilities (i.e., munis and co-ops)

notes

Iowa was one of the first U.S. states to establish a net-metering policy and its policy is now more than 30 years old. However, net metering is addressed only fleetingly in the states administrative code. The current policy is addressed in tariffs, filed by MidAmerican Energy and Interstate Power & Light, and approved by the Iowa Utilities Board, do not address REC ownership, and language addressing eligible generators does not favor third-party ownership. Net metering and third-party ownership in Iowa have attracted significant legal attention during the past decade; a case involving third-party ownership is currently pending before the Iowa Supreme Court.
