Transforming McHenry County's Energy Future

What is a Battery Energy Storage System?
Think of a battery energy storage system (BESS) as a giant rechargeable battery for the electrical grid. Just like your phone battery stores power for when you need it, BESS facilities store electricity when it’s abundant and release it when demand is high.
But unlike your phone battery, these systems are massive, sophisticated pieces of infrastructure that can power thousands of homes and provide critical services that keep the entire electrical grid running safely and smoothly.
Benefits of BESS
Battery energy storage systems provide crucial benefits to both the electrical grid and local communities. By storing energy during off-peak hours and releasing it when needed most, BESS projects help stabilize electricity costs, reduce strain on aging infrastructure, and provide reliable backup power when it’s needed most. For McHenry County, Monarch Grid means enhanced energy security, economic development, and technology leadership, all while maintaining the rural character that makes your community special.
Millions to McHenry
Monarch Grid delivers approximately $5 million in annual property tax revenue flowing directly into schools, roads, and emergency services - enough to cover roughly 11% of the McHenry County Sheriff's budget and approximately 3 times Prairie Grove's entire annual property tax revenue. Plus 110 construction jobs sourced locally. This isn't just an investment, it's infrastructure that strengthens the community's financial foundation for generations.
Lower Energy Bills
McHenry County residents pay about $236 per month for electricity - 6% higher than the national average. ComEd customers saw 20-25% bill increases in 2025 due to record-high capacity auction prices. Monarch Grid helps break this cycle by storing electricity when it's abundant and releasing it when demand peaks, adding supply exactly when it's needed most to keep prices from spiking.
Grid Stability & Reliability
When the grid gets stressed during peak demand or severe weather, Monarch Grid provides instant backup power. Our 600 MW system can support approximately 450,000 homes during peak demand, significantly reducing the risk of blackouts and rolling outages for homes and businesses across McHenry County.
Proven Results Across the Country
Battery energy storage isn’t theoretical, it’s already delivering results in communities across America:
Texas, September 2023
During record heat, batteries released 1.8 GW of power, reducing energy prices by nearly 50% and powering approximately 434,000 homes during peak stress.
California, September 2024
During a late-season heat wave, batteries discharged a record 8.35 GW — over 21% of total demand. Unlike 2020 and 2022, no rolling blackouts were needed.
Texas, 2024
Battery storage contributed to $750 million in consumer savings since 2023 by reducing peak power prices.
How BESS Works
Charge
During off-peak hours, the battery system stores excess electricity from the grid using advanced charging systems designed for maximum efficiency and safety.
Store
Advanced battery technology safely holds the electrical energy until it’s needed, with sophisticated monitoring systems ensuring optimal performance and safe operation.
Discharge
When demand peaks or additional power is needed, the stored energy is instantly released back to the grid, supporting local communities with reliable power.
Our Commitment to Partnership
Monarch Grid is more than an energy project, it’s our commitment to being genuine partners in McHenry County’s future. We believe the best projects happen when developers listen to community concerns, incorporate local input, and work collaboratively toward shared goals. From day one, we’re dedicated to transparent communication with residents, open dialogue with county officials, and responsive engagement with local stakeholders throughout every phase of development.
Our team prioritizes safety, environmental stewardship, and meaningful economic benefits that strengthen the community for generations to come. We understand that earning your trust requires consistent action, not just promises. That’s why we’re committed to careful, respectful development that enhances McHenry County rather than simply adding another industrial facility. This isn’t about imposing a project on your community, it’s about working together to bring advanced energy infrastructure and significant economic benefits through genuine partnership and shared vision,
