Revision Energy's Guy Marshall leads workshop on solar field expansion plans

Batteries are emerging as a game-changer for energy management in Cumberland, Maine, as discussed in the Town Council workshop on August 11, 2025. The meeting highlighted how battery systems can significantly reduce peak demand charges for local businesses, particularly using the Boot Bay aquarium as a prime example.

During the session, Guy Marshall from Revision Energy explained that the aquarium's electricity usage spikes dramatically when its large pumps are activated. Utilities monitor energy consumption in 15-minute increments and charge based on the highest peak demand, which can lead to inflated costs for businesses that only require that power briefly. By integrating battery systems, the aquarium can draw energy from batteries first, lowering its peak demand and consequently reducing monthly charges.

Marshall emphasized the importance of staggering the operation of the pumps to further optimize energy use and costs. This innovative approach not only benefits the aquarium but could also set a precedent for other local businesses looking to manage their energy expenses more effectively.

The workshop also included administrative tasks, such as approving minutes from the previous meeting, but the focus on energy efficiency and sustainability through battery use stood out as a significant takeaway. As Cumberland continues to explore renewable energy solutions, the implications of this discussion could lead to broader adoption of similar technologies across the community.
