Securing a Diverse Energy Portfolio
A diversified power portfolio enables our community to meet customer needs for reliability and affordability while also advancing our goals for sustainability and environmental stewardship.
Why Energy Diversity
Much like a mutual fund or retirement plan stabilizes gains and mitigates risk through diverse investments, we can ensure greater affordability and reliability for our power supply by contracting for capacity and energy from a range of networked resources. This includes supply from renewables like wind and solar, or more traditional market purchases that do not specify the source of the power to be sold.
GHBLP carefully works with our Market Participant, the Michigan Public Power Agency (MPPA), to select energy partners and short and longer-term power purchase agreements that support our community’s values of diversity, energy risk management, fiscal and environmental responsibility.
2025 Energy Purchases
26% Renewable Energy Purchases in 2025
In 2025, renewable energy accounted for 26% of GHBLP's annual electricity purchases, reflecting the community's continued support for cleaner energy while maintaining reliable service and affordable rates. Through its membership in the Michigan Public Power Agency (MPPA), GHBLP has secured several long-term power purchase agreements with regional wind and solar providers, enabling the utility to exceed Michigan's Renewable Portfolio Standard (RPS) requirements.
GHBLP remains committed to expanding its renewable energy portfolio and will continue to evaluate new wind, solar, and emerging energy technologies as they become available, incorporating additional resources when they provide economic value and long-term benefits for the community.
Working Together
GHBLP represents just one small system in a statewide, national, and global effort to reduce dependence on fossil fuels and steward our climate future. As members of the MPPA, we collaborate with other like-minded municipal utilities on joint action projects in planning, transmission infrastructure, and renewable projects.
