All battery enclosures will be a minimum of [25] feet from the property lines with the closest residence over [600] feet away. In addition to the battery enclosures, the project will also include equipment similar to what you would find in a substation: inverters, transformers, electric wires and poles, small buildings for communications equipment, etc.

Also, there will be climate control equipment integrated into the containers similar to the HVAC systems you would find in a home or business. Surrounding the project there will be fencing for security purposes and whatever additional screenings the County Board may require. On the South and East portions of the site, there will be a sound fence to limit sound pollution for neighbors.

We take into consideration many factors when deciding on a site location. This site was selected for the following reasons

1. Proximity to existing substation and electrical infrastructure
2. Industrial nature of property
3. Previously developed parcel
4. Minimal environmental impacts

Safety in the design, construction, and operation of energy storage systems is our highest priority. Through code compliance, effective design, operation, and maintenance, battery energy storage systems are safe and the risk of thermal runaway and subsequent fire is extremely low. These types of low risk activities are familiar in our everyday lives, such as heating our houses with natural gas or driving a car.

Each battery enclosure is controlled and monitored 24/7/365, allowing the facility to be closely managed and safely operated. Each enclosure is equipped with an integrated system of sensors, alarms, and fire detection and suppression systems. The operational management systems will be designed, installed, and operated according to applicable national and local fire code standards and regulations, which include energy storage-specific regulations. Additionally, we will continue to have regular contact with the local fire department to facilitate coordination and training opportunities that ensure first responders are adequately trained to handle any system incidents or safety concerns.

Energy storage systems charge and store electricity when it is least expensive and/or when there is a surplus on the grid so that it can be used when electricity is most needed due to high costs and/or limited supply.

Energy storage projects are vital to ensure grid reliability and resiliency, especially as we see increases in the number of intermittent generators such as solar and wind on the electrical grid. They can assist in more efficiently using utility resources by expanding their capability to meet peak demand. Additionally, during periods of grid stress, these energy storage systems can provide valuable extended operating power.

When installed along existing transmission lines, a battery energy storage system can help regulate the transmission of large quantities of electricity and ensure the reliability and stability of the line are maintained in times of stress. Systems of this type can also be used as an alternative to new transmission lines when electrical congestion becomes a concern for the surrounding infrastructure. Depending on the location and magnitude of storm impacts, the project could also help reduce the length and number of outages of the supply of electricity to the surrounding region during major storm and tornado events or accelerate the restoration of electricity in the event of an outage.

Our energy centers use proven technology, such as lithium-ion batteries, which have been successfully deployed throughout the United States and here locally, in the Commonwealth of Massachusetts. The US has hundreds of operational grid-scale battery energy storage system (BESS) projects totaling thousands of megawatts (MWs) of capacity.

Examples of existing battery energy storage systems East Point has developed and/or in operation: 

• Dry Bridge BESS (20 MW) owned by Dominion Energy in Chesterfield County, VA
• Sunset Ridge Energy Center (10 MW) owned by East Point Energy in Frio, TX
• (Under Construction) Citrus Flatts Energy Center (100 MW) owned by East Point Energy in Harlingen, TX

We expect this facility to be in operation for at least 20 years, though the energy system’s useful life can vary based on use, maintenance, and augmentation activities.

The project will follow decommissioning requirements established through the relevant national/international operation codes and county ordinances, which will safely remove all equipment from the site and transport component parts to the appropriate recycling or waste management facilities at the end of the project life.
