Could a planned blackout happen here?

Pacific Gas & Electric Co. (PG&E) made strategic and unprecedented decisions last month to temporarily shut off power to large swaths of its California customers to avoid a potential wildfire disaster due to high wind conditions. Schools closed, people scrambled to purchase supplies, patients in need of medical care were forced to evacuate, homes went […]

Utilities launch transmission grid study

The CapX2020 utilities have announced their plan to study the transmission system that serves the Upper Midwest to identify system improvements and infrastructure upgrades that may be needed to achieve the ambitious 2050 carbon reduction goals established or proposed by utilities and policymakers. The CapX2050 Transmission Vision Study will look at maintaining a safe, reliable […]

Partners start outreach on transmission rebuild project

Great River Energy and Missouri River Energy Services (MRES) are planning to re-build approximately 38 miles of power lines in Big Stone and Stevens counties in Minnesota. The utilities co-hosted two public information open houses to share details about the re-build project, answer questions and listen to feedback in August. The project is needed to […]

Kandiyohi Power using new technology to balance grid

Kandiyohi Power Cooperative (KPC) is seeing the benefits of today’s sophisticated technology since it finished integrating its load management system with Great River Energy’s new demand response management system (DRMS) this spring. Load management is the process of balancing the supply and demand of electricity on the electric system by adjusting or controlling electric loads, […]

Critical transmission upgrade finishes strong

The high-voltage, direct-current (HVDC) upgrade that has been years in the making was completed May 17 and put into commercial use. This project has been one of Great River Energy’s most significant capital investments over the last several years and was needed to help ensure the continued reliability of one of the cooperative’s most critical […]

The bees’ knees of habitats created for pollinators

National Pollinator Week, recognized from June 17-21, celebrates the humble bees, butterflies, bats and other bugs that pollinate and help more than 70 percent of the world’s crops. Electric cooperatives are among the many organizations that have focused on the plight of these pollinators and have done their part to re-establish their native habitat. Great […]

Intern invents computer program to improve safety

What used to take four months of an intern’s time now takes 10 minutes. “Interns used to be assigned to manually run calculations on our lines to determine the incident energy for transmission line arc flash hazards,” said Melissa Phillips, Great River Energy engineer and intern mentor. “These reports would take a typical intern four […]

Utilities study nuclear threats to grid

The Electric Power Research Institute (EPRI) recently released a report on a study it performed over three years about how an electromagnetic pulse (EMP) caused by a nuclear explosion at high altitudes could impact the electric grid. EPRI gathered research in partnership with the Department of Energy, the Defense Threat Reduction Agency, three national laboratories, […]

Co-ops work together to restore system after Winter Storm Wesley

When Winter Storm Wesley ripped through southern Minnesota on April 11, crews from Great River Energy, neighboring utilities and member-owner cooperatives got to work clearing fallen poles from roads, setting new poles, stringing wire and bringing the power back to the more than 8,300 end-use members who experienced an outage.
