A recently published working paper by the Great Plains Institute (GPI), titled “Consumer Savings, Price, and Emissions Impacts of Increasing Demand Response in the Midcontinent Electricity Market,” explores the effects of increasing the use of demand response (DR) assets in the Midcontinent Independent System Operator’s (MISO) wholesale energy market.

Analysis: The Effect of Growing Wind Energy on Midwestern Electricity Prices Over the Past 8 Years

September 19, 2017 in Electricity Author: Steve Dahlke

A recently released GPI report looks at the extent to which growth in wind energy has reduced electricity prices in the Midwestern market. In conjunction with the Colorado School of Mines, GPI undertook a comprehensive empirical investigation and found a significant decrease in electricity prices attributed to wind energy in the Midcontinent ISO (MISO) market.

Impact Wind Generation Cover

The Midcontinent Independent System Operator, known as MISO, is the second largest organized competitive wholesale electricity market in the U.S., serving 14 states with over 180 gigawatts of generation capacity, encompassing 6,427 generating units, and 65,800 miles of transmission lines. (FERC, 2017) Wholesale electricity prices in MISO have decreased over the past several years, as both natural gas prices have fallen and as large amounts of wind generation capacity have been added.

Why Large Competitive Electricity Markets Benefit Wind Energy

April 22, 2017 in Electricity Author: Steve Dahlke

On April 1, 2005, the Midcontinent Independent System Operator (MISO) launched a wholesale energy market and began centrally dispatching power generation throughout the central United States. One result from this market reform was the reduction of wind energy curtailments. In fact, our recent analysis indicates wind capacity factors on the MISO system increased about 5-7% after the market launch. For a large 100 MW wind plant, a 5-7% increase is equivalent to about an extra $2 million in revenue per year at typical prices. Continue reading »

Give wind a chance: new infrastructure needed to expand renewable energy

February 23, 2015 in Electricity Author: Steve Dahlke

Wind TurbineThose who have lived in the Midwest a long time may remember the power line fights of the 1970’s, when farmers across Minnesota organized against electric transmission development. One large project required deployment of half of Minnesota’s highway patrol troopers to complete construction. One reason for the controversy back then was infrastructure projects were planned behind closed doors with minimal regulatory oversight. Continue reading »
