Distributed Generation

Distributed Generation

Minnesota’s Net Metering Policy

Minnesota is one of many states that encourage small renewable energy systems to be installed at residences and businesses. According to Minnesota Statute 216B.164, all utilities shall buy back any excess energy that reaches the distribution grid produced by a qualifying facility having less than 40 kW capacity at the average retail energy rate for the applicable rate schedule. This means for any wind or solar system with a total capacity size of less than 40 kW and installed at an existing Renville-Sibley Cooperative Power (RSCPA) service location, RSCPA will buy the excess energy produced by the renewable system at an average retail energy rate.

For renewable systems at a capacity of 40 kW or larger, RSCPA will still buy back the excess power produced by the renewable system that reaches the grid. However, the amount that the power is bought back is at avoided cost.

Interconnection Renewable to the Distribution Grid

Renville-Sibley has 31 active distributed generation facilities with a total nameplate capacity of 853.17 kW.  Assuming a 17% overall capacity factor, these systems are expected to produce 1,270,540 kilowatt hours in 2018.  The amount of distributed generation on Renville-Sibley’s system is increasing each year. 

When comparing the amount of interconnected renewable energy production to the total utility single and small three phase energy sales, RSCPA leads the state in renewable systems penetration.

RSCPA will attempt to accommodate the interconnection of all member renewable projects. All distributed generation projects including renewable systems are to follow the State of Minnesota Interconnection Process for Distributed Generation Systems. This document outlines the process, timelines, technical requirements and cost ownership to interconnect a renewable system to the distribution grid. Due to the high penetration of renewable systems in parts of RSCPA’s system, some renewable system projects may require additional engineering studies to determine what electrical grid changes need to occur to safely interconnect additional generation.

RSCPA procedure for interconnecting renewable systems along with the State of Minnesota Interconnection Process for Distributed Generation Systems documents can be found under Documents and Forms. To initiate any interconnection of a renewable system, RSCPA requires the Interconnection Application to be completely filled out and returned to RSCPA along with any applicable non-refundable application fees.
