In 2022, the United States consumed a total of 4.07 trillion kilowatt hours (kWh) of energy per year, the highest amount ever recorded, and 3.2% higher than the year prior, according to the U.S. Energy Information Administration. The power demand in the U.S. fluctuates based on factors such as population growth, economic activity, technological advancements, and energy efficiency measures. With aggressive carbon reduction, electrification, and energy efficiency targets set at both federal and state levels, electric cooperatives are increasingly concerned about the strain on an already outdated grid and the impact on end-of-line reliability.
More than 25% of U.S. households experience energy insecurity regularly, as reported by the Residential Energy Consumption Survey (RECS). The aging infrastructure—including power generation, transmission, and distribution systems—requires significant upgrades, which are both costly and time-consuming. Utility cooperatives must implement a range of solutions to ensure that all members have access to reliable and affordable utility services. One of the solutions this blog will dive into is microgrids.
Microgrids Leading the Charge Toward the Future
For rural electric cooperatives, end-of-line members often live in remote areas far from the cooperative’s main power generation and transmission facilities. These remote locations are more vulnerable to power outages due to weather events and equipment failures, resulting in a less reliable power supply for end-of-line customers.
Microgrids act as Distributed Energy Resources (DERs) that integrate with generators, battery energy storage, and other renewable energy resources. During normal grid operations, microgrids can operate as part of the grid, discharging power as needed. However, when the grid goes down or experiences intermittent power supply, microgrids can run autonomously using their local DERs and control mechanisms.
How Does a Microgrid Work?
Microgrids are localized, small-scale energy systems that generate, distribute, and manage power distribution. They typically include various sources of generation, such as solar, wind turbines, and natural gas, paired with energy storage solutions to store excess electricity generated during periods of low demand or high renewable energy production. This stored energy is then discharged during peak demand times or when renewable sources are not generating power.
As more assets begin to electrify, the electrical grid faces increased demand. While microgrids have the capability to operate independently, they can also be integrated with the main grid. This integration allows for two-way power flow, enabling excess energy to be exported to the grid when the microgrid generates more than it needs and importing power when local resources are insufficient.
Microgrids are often utilized in areas that are vulnerable to grid outages, extreme weather events, or remote locations with unreliable grid access. They enhance grid resiliency by providing a reliable source of power during these disruptions.
Stark Tech’s Microgrid on a Skid: An Effective End-of-Line Solution
Stark Tech’s Microgrid on a Skid (MGS) is an innovative application containing the components necessary for a durable and scalable microgrid with battery energy storage sizing up to 1 ½ MWh / 750 kVA per unit. Designed and assembled as a compact and portable unit, the MGS can be deployed quickly without the need for extensive on-site construction. Its modular and scalable design allows for increases in power capacity and the addition of more energy sources, adapting to changing requirements efficiently.
By adopting advanced microgrid solutions like Stark Tech’s MGS, utility cooperatives can significantly enhance the reliability and resilience of their power supply, ensuring that all members, including those at the end-of-line, receive consistent and dependable energy services.
