Minnesota Power, a division of ALLETE, Inc., and the Minnesota National Guard signed a memorandum to join forces to build a 10MW solar energy project at Camp Ripley. The project will be the largest solar energy installation on military property in the state. The utility will also identify ways to help Camp Ripley reduce its energy usage by 30% and install backup generation for energy security.
Minnesota Power has been the energy provider to Camp Ripley for decades. The solar project envisioned by Minnesota Power and the Guard, subject to regulatory approval, would cover nearly 100 acres of underutilized government property at the Camp with PV panels on racks.
“To provide cleaner energy forms is the mission, and both Minnesota Power and our National Guard are on the front lines,” said ALLETE Chairman, President and CEO Al Hodnik. “This project helps meet our goal of achieving the state’s solar mandate and it advances our company’s EnergyForward goal of providing a balanced mix of one-third renewable, one-third coal and one-third natural gas energy sources reliably and affordably.” He added that the solar project will also bring employment and new business into the region.
The solar farm and backup generation will be designed and constructed to allow Camp Ripley to use the energy produced by the project during infrequent periods when the electric grid is down, providing enhanced energy security for the military site, which benefits all Minnesotans. At 10 MW, it will be among Minnesota’s largest single-site solar arrays, producing more electricity than the base normally requires. During non-emergency operation the solar energy produced would flow into Minnesota Power’s electric service territory, which encompasses 26,000 square miles in central and northern Minnesota.
Projected to cost $25 million, the solar energy project could be completed in the 2015-2016 time frame. Minnesota Power has been evaluating solar generation projects that will help the company comply with a solar energy standard enacted in 2013 by the Minnesota Legislature. The law requires the company to procure 1.5% of non-exempt energy from solar resources in a manner consistent with Minnesota Power’s integrated resource planning while providing competitive electric rates to customers.
“Completion of the Camp Ripley solar project will help Minnesota Power achieve about one-third of its requirement under the state’s new solar mandate,” said Al Rudeck, Vice President Strategy and Planning. At the same time, the project will help the Minnesota National Guard meet energy conservation objectives outlined by the Department of Defense. And Camp Ripley would achieve an energy security priority by gaining the ability to function completely independent of the electric grid in emergency situations. The project will showcase a clean energy partnership between an innovative public utility and the military.
The National Guard and Minnesota Power will work together to identify and complete programs that will help Camp Ripley meet its energy savings goal of 30% (beginning with a 2003 baseline). This spring and summer, Minnesota Power personnel conducted an energy efficiency evaluation at the camp under the auspices of the company’s Power of One Conservation Improvement Program. More than 50 different energy conservation measures were recommended.
Part of the memorandum signed today outlines how Minnesota Power will install reciprocating engines – either diesel or natural gas -- at Camp Ripley that will serve a dual purpose. First, the engines would provide capacity and peaking energy to Minnesota Power, operated through remote dispatch during periods when energy market conditions call on it. Secondly, this “backup generation” could provide emergency generation to Camp Ripley.
