Minnesota Distributed Generation Tariff Development and Resources

Welcome to the online resources page for the regulatory proceedings to establish Distributed Generation Tariffs and Interconnection standards in Minnesota.

NOTE (AUGUST 2009) – The MN PUC has re-done their web site and has not implemented a redirect of links to old content to their new locations hence many of the links pointing to the old PUC site are not working.

Update April 2007     Folks, the regulatory proceedings are over and the utilities have put their interconnection standards and procedure documents on their web sites. Here are the links:DG Interconnection Information for MN Utilities Xcel Energy’s Interconnection Guidelines and Tarifs for Customer-Owned Generation Minnesota Power’s Interconnection Guidelines and Tariffs for Customer owned Generation Interstate Power’s Interconnection Guidelines and Tariffs for Customer owned Generation Otter Tail Power’s Interconnection Guidelines and Tariffs for Customer owned Generation Dakota Electric Association’s Interconnection Guidelines and Tariffs for Customer owned Generation NOTE: Although clunky, you can view the archived filings and schedules by going to the PUC’s e-Filing System and entering the docket number of interest: Xcel Energy Docket: 04-2055 MN Power Docket: 04-2030 Interstate Power Docket: 04-2041 Otter Tail Power Docket: 04-2013 Dakota Electric Docket: 04-2049

Information on DG Tariffs in Minnesota

1. Public Utilities Commission Generic Distributed Generation and Interconnection Proceeding(Docket No. E-999/CI-01-1023)

The Minnesota Legislature required that the PUC adopt standards for interconnection of distributed generation that uses natural gas or an equally clean or cleaner fuel under 10 MW in Minnesota that should remove some barriers to deployment of these technologies.

• PUC Order Approving Dispersed Generation Plan – In the Matter of the Petition of Northern States Power Company for Approval of its 1991 Resource Plan, April 5, 1993 (Docket No. E-002/RP-91-682)
  This interesting piece of the historical regulatory record contains the following statement. “The Company considered dispersed generation a resource option worth developing for several reasons. Disbursed generation can supply part of the system’s future need for peaking capacity. It can meet specific customers’ needs for backup generation, arguably at lower total costs than customer-owned backup capacity. It can improve overall system reliability. It can reduce transmission and distribution costs and losses. It can help position the Company to exploit new technologies, such as fuel cells, being developed outside the traditional large power plant context.”

INFORMATION FROM OTHER STATES, FERC, MISO, PJM, AND IEEE

California

California’s electricity woes have led the state down a path to stabilize their electricity supply. They have instituted a program where for the next two years any qualifying distributed power project will be exempt from stand-by charges for the next 10 years. Even more incentives are provided to solar pv distributed generation projects of up to 1 MW in size. The primary Distributed Generation regulatory proceeding at the California PUC is Rulemaking 99-10-025

New Jersey

• Natural Gas Price Breaks for Distributed Generation – New Jersey
  New Jersey Natural Gas Company (NJNG) received approval in January 2003 from the New Jersey Board of Public Utilities (BPU) to offer a special pricing plan to residential and commercial customers who use natural gas to fuel distributed generation (DG) technologies like fuel cells or microturbines. Under the rates, commercial and residential DG projects could see savings of up to 50 percent on their fuel costs. More…

New York

In December 1999, the New York Public Service Commission (NYPSC) issued a final order addressing interconnection of distributed generation (DG) resources of 300 kilowatts (kW) or less. The order addresses general technical guidelines for interconnection and application procedures. As part of an ongoing review of the requirements, substantive revisions were proposed and adopted in 2002 and 2003. Further review process in 2003 yielded changes consisting primarily of an increase in the upper capacity threshold from 300 kW to 2 MW, the adoption of an Underwriter’s Laboratories (UL) standard for equipment certification, and the extension of the applicability beyond only radial distribution systems to also now include network distribution systems. The NY PSC adopted new rules in November 2004.

• New York State Standardized Interconnection Requirements For Distributed Generators 2 MW or Less Connected In Parallel With Utility Distribution Systems – as of November 2004
• Listing of Certified Distributed Generation Equipment – as of December 2004
• Order Modifying Standardized Interconnection Requirements – issued by the NY PSC, November 17, 2004 [Order on Gas Transportation Rates for Distributed Generation Technologies – issued by the NY Public Service Commission, August 4, 2004 [View all documents related to New York’s Stand-by Rates Dockets 02-E-0551, 02-E-0779, 02-E-0780, 02-E-0781, 02-E-1108

New York Department of Public Service has a section on Distributed Generation and also a very nice section on the Debate over Stand-by Charges for Distributed Generation

Texas

The Texas Public Utility Commission (PUC) adopted final rules (Project No. 21220) in December 1999 addressing technical and contractual issues related to installing distributed resources. The Texas standards place the burden of proof on the utility to show if an interconnection should be disallowed. The Commission adopted a standard interconnection agreement and a standard tariff interconnection form. The PUC also released a final version of their Distributed Generation Interconnection Manual (Project No. 21965).

• Texas Distributed Generation Interconnection Manual – Final- March 2001
  • § 25.211 – Interconnection of On-Site Distribution Generation (DG)

  • Texas Distributed Generation Tariff Form – [MS Word]
  • Interconnection Agreement Form – [MS Word]

Wisconsin

Wis. Stat. § 196.025(4)) required the WI Public Service Commission to study the establishment of a program for providing incentives for the development of high-efficiency, small-scale electric generating facilities. New rules for inteconnection of DG projects of 15 MW and less were adopted in February 2004.

  FERC has accepted PJM Interconnection’s proposal that makes it easier for small generators (less than 2MW) to connect to the electric system and participate in PJM’s wholesale electricity market, the world’s largest. The PJM working group is now working on standards for DG units between 2-10 MW.
