The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

Summary:

In 2007, Minnesota legislation modified the state's existing non-mandated renewable energy objective, creating a mandatory renewable portfolio standard (RPS) called the Renewable Energy Standard for its public utilities, generation and transmission electric cooperatives, municipal power agencies, and power districts operating in the state. In 2013, H.F. 729 created a statewide goal of 10% of retail electric sales from solar by 2030.

Eligible Technologies

Electricity generated by solar, wind, hydroelectric facilities less than 100 megawatts (MW), hydrogen, and biomass—which includes landfill gas, anaerobic digestion, municipal solid waste, the organic components of wastewater effluent, and sludge from public treatment plants (excluding waste sludge incineration)—is eligible for the standards and the objective. After January 1, 2010, hydrogen must be generated by other eligible renewables in order to be eligible.

Requirements

By the end of 2020:

  • Nuclear utilities (Xcel Energy) must generate or procure 30% of their retail electricity sales using renewable energy and an additional 1.5% from solar.
  • All other public utilities must procure or generate 20% of their retail electricity sales using renewable energy and an additional 1.5% from solar.
  • Non-public utilities must procure or generate 20% of their retail electricity sales using renewable energy.  

Xcel Energy Standard

The RPS standard for Xcel Energy requires that the following percentages of retail electricity sales be generated or procured using eligible renewable sources by December 31 of the given year:

  • 15% by 2010
  • 18% by 2012
  • 25% by 2016
  • 30% + 1.5% solar by 2020 

Standard for Non-Xcel Public Utilities

The RPS standard for other Minnesota public utilities requires that the following percentages of retail electricity sales be generated or procured using eligible renewable sources by December 31 of the given year:

  • 12% by 2012
  • 17% by 2016
  • 20% + 1.5% solar by 2020
  • 25% + 1.5% solar by 2025 

Standard for Non-Public Utilities

The standard for other Minnesota utilities requires that the following percentages of retail electricity sales be generated or procured using eligible renewable sources by December 31 of the given year:

  • 12% by 2012
  • 17% by 2016
  • 20% by 2020
  • 25% by 2025

Carve-Outs for Public Utilities

In 2013, H.F. 729 was enacted, creating a 1.5% carve-out for solar for public utilities to meet by the end of 2020, 10% of which must be met with photovoltaic (PV) systems that are 20 kilowatt (kW) nameplate capacity or less.

In addition to the above solar carve-out, Xcel Energy is required to have at least 25% of retail electricity sales generated by wind energy or solar energy systems by 2020, with solar limited to no more than 1% of this additional requirement. In effect, this means that the wind standard is at least 24% of retail electric sales, the solar standard is 1.5% and may contribute up to another 1%, and the "remaining" 5% may be generated using other eligible technologies.

For the purpose of calculating the solar requirement, the following types of customers are not included: iron mining extraction and processing facilities, including scram mining; and paper mills, wood product manufacturers, sawmills, or oriented strand board manufacturers.

Credit Multipliers

The 2007 legislation required the Minnesota Public Utilities Commission (PUC) to establish a program for tradable renewable energy certificates (RECs) by January 1, 2008. A REC is created for each MW of renewable energy generated. To comply with the RPS requirement, a utility must retire RECs. Notably, Xcel Energy may not sell RECs to other Minnesota utilities for RPS compliance purposes until 2021. For the purposes of the solar standard, only RECs associated with solar installed and generated in Minnesota on or after May 24, 2013, but before 2020 are eligible.

The PUC approved the Midwest Renewable Energy Tracking System (M-RETS) for this purpose and required all utilities to register renewable generation assets by March 1, 2008. Only RECs recorded and tracked through the M-RETS can be used for compliance. The program treats all eligible renewables equally and may not ascribe more or less credit to energy based on the state in which the energy was generated or the technology used to generate the energy. The purchase of RECs through M-RETS may be used in utility green pricing programs, subject to the shelf life described above. Consistent with M-RETS operating procedures, RECs must remain "whole" and may not be disaggregated into separate environmental commodities (e.g., carbon emission credits).

RECs will have a trading lifetime of 4 years according to the year of generation (e.g., RECs generated during 2008, regardless of the month, expired at the end of 2012). In July 2014, the PUC clarified that the generator of renewable energy owns all RECs.

Compliance

Utilities are required to file annual compliance reports with the PUC detailing their retail sales, REC retirements, and REC trading activities. If the PUC finds a utility is non-compliant, the commission may order the utility to construct facilities, purchase eligible renewable electricity, purchase RECs, or engage in other activities to achieve compliance. If a utility fails to comply, the PUC may impose a financial penalty on the utility in an amount not to exceed the estimated cost of achieving compliance. The penalty may not exceed the lesser of the cost of constructing facilities or purchasing credits, and proceeds must be deposited into a special account reserved for energy and conservation improvements.

Compliance reports from individual utilities for 2008-2013 are available from the PUC through the E-Docket System. In 2013, the Division of Energy Resources published a compliance progress report for compliance through 2011, stating that utilities are on track to comply with 2012 goals.
