Middletown Recreation Center Embraces a Resilient and Sustainable Future with a New Microgrid

In a significant step towards energy independence and sustainability, the Middletown Recreation Center has completed the installation of a new microgrid system. This project is a cornerstone of the city’s broader efforts to modernize its infrastructure and ensure the community’s safety and comfort, particularly during extreme weather events.
The new recreation center, built on the former site of the Woodrow Wilson Middle School, is not only a hub for community activities with renovated gyms and pools but also serves a vital role as a designated heating and cooling center during power outages. The microgrid is the key to this resilience, allowing the facility to operate independently of the main power grid.
The system is a complex, hybrid energy solution designed and engineered by Clarke Energy in collaboration with other partners. Controlled Air, Inc. worked with Clarke Energy to create an energy-efficient solution that integrated a Yanmar combined heat and power (CHP) unit and a Yanmar gas heat pump (GHP) system. The core of the microgrid is the 35kW CHP unit, which provides both electricity and high-efficiency hot water for showers and the pool. This is complemented by a solar photovoltaic (PV) array that generates renewable electricity, with a battery energy storage system (BESS) to save surplus energy for later use. A backup gas-fueled generator from Kohler provides an additional layer of resilience, ensuring the facility can remain powered for extended periods.
This innovative system is designed to provide both parallel power during normal operation and “island mode” capability during a grid outage. The entire system is managed by a centralized microgrid controller, which optimizes the different energy sources for maximum efficiency and reliability. The project is expected to reduce the center’s carbon dioxide emissions by 192 tons per year, aligning with the city’s goals for a more sustainable future.
The Middletown Recreation Center microgrid is an excellent example of how communities can invest in infrastructure that not only serves their daily needs but also provides critical support in emergencies. It represents a forward-thinking approach to energy management, combining sustainability with an unwavering commitment to public safety and resilience.
The Middletown Recreation Center’s new system is fully protected by a 20-year parts and labor contract. Controlled Air and Yanmar are committed to providing a reliable, long-term, and energy-efficient solution by guaranteeing dedicated parts and service for the equipment.

The Bridgeport Microgrid was acquired by Scale Microgrid Solutions in 2021.

Bridgeport Microgrid is a partnership between OR&L Construction in Branford, Controlled Air and Power Island Energy in Jacksonville, Fla.

Controlled Air, Inc. will be in charge of the design build concept. This includes the design and installation of the Congeneration System, chilled water system, controls system, underground piping, and thermal loop for both chilled and hot water.

A microgrid is a power system designed to provide power to buildings continuously, even in times of natural disasters or when the main electrical grid fails.
The project is part of a municipal pilot program launched through the state Department of Energy and Environmental Protection in 2013.
In addition to providing power to key municipal buildings, Bridgeport’s system will use the generators’ excess heat to provide heating and cooling to City Hall, police headquarters and the nearby Cabaret building.
According to DEEP, Bridgeport microgrid will own the generation for the city’s microgrid.

The microgrid is expected to be operational by July 2017.
