TO: FROM:
ERMU Commission Tom Sagstetter – Conservation & Key Accounts Manager
MEETING DATE: AGENDA ITEM NUMBER:
January 12, 2021 2.3
SUBJECT:
Cogeneration and Small Power Production Tariff- Schedules 1 and 4
ACTION REQUESTED:
Adopt the revised Schedule 1 and 4 of the Cogeneration and Small Power Production Tariff
BACKGROUND:
Every municipal electric utility should have a policy reflecting the expectationsand obligations
of the utility and customers who seek to interconnect their own electric generation facilities
with the distribution system. For ERMU these facilities consist of wind or solar photovoltaic
systems that are less than 40kW.
To allow for consistency over all municipals in the state, ERMU staff continues to use models
established by the Minnesota Public Utilities Commission (MN PUC) and modified by the
Minnesota Municipal Utilities Association (MMUA) and Minnesota Municipal Power Agency
(MMPA). The policies were adopted by the Commission at the February 13, 2018 commission
meeting, and revised policies were adopted at the May 14, 2019 commission meeting.
DISCUSSION:
The policies and rules outline that, at least annually, the Commission will review and adopt
Schedules 1 and 4 of the Cogeneration and Small Power Production Tariff. The two schedules
reflect the average retail rates for the applicable class of customer and the method of
reimbursement selected by the customer owning the distributed generation facility. Attached
are the updated Schedules for 2021.
