Resource Plan



Missouri River Energy Services (MRES) filed its 2006-2020 Resource Plan with the Minnesota Public Utilities Commission on July 1, 2005, and filed a Supplement to that Plan on May 9, 2006. The Resource Plan provides an analysis of the future electricity needs of the 57 S-1 power supply members of MRES in the states of Iowa, Minnesota, North Dakota, and South Dakota. The forecast indicates MRES needs additional baseload resources beginning as early as 2010 to satisfy an increase in member demand for electricity.

MRES currently has only one source of baseload generation, a 280 MW share of Unit 1 of the Laramie River Station which went on-line in 1980, supplemented by a number of peaking resources. After 30 years, MRES member needs have outgrown these resources, and MRES will need to add approximately 290 MW of capacity over the next 15 years.

The MRES Resource Plan details our plan to meet this need, in part, by the addition of the Big Stone II Power Plant as well as other peaking and renewable energy resources. Now that the Big Stone II Power Plant is cancelled, MRES is studying its options for future power supply resources. These plans will be included in the next IRP.

We also found that an additional 85 megawatts of generation could be saved through MRES members' use of demand-side management programs. The Resource Plan specifies the preference of MRES to use wind generation to achieve its commitment to meet the Minnesota Renewable Energy Standard to supply 7 percent of resources from renewable energy by 2010, 12 percent by 2012, 17 percent by 2016, 20 percent by 2020, and 25 percent by 2025. 

In fact, MRES presently owns wind generation and its renewable energy plans include expansion of its wind portfolio and exploration of other renewable energy technologies.

MRES will increase its wind power capacity to 82.4 MW once the Rugby Wind Project starts commercial operations in early December 2009. The wind farm is located near Rugby, N.D., and will include 71 wind generators with a total capacity of 149 MW. MRES has contracted for 40 MW of power from the facility, which is being developed by Iberdrola Renewables, Inc.

MRES also derives wind energy from facilities near the Minnesota communities of Worthington, Marshall, and Odin. With the addition of the Rugby project, about 12 percent of the MRES energy will be coming from non-hydroelectric renewable resources.

The next MRES Resource Plan is scheduled to be filed with the MPUC on July 1, 2010.
