Portsmouth Naval Shipyard Microgrid and Ancillary Services

EW-201350

Objective

The objective of this project is to demonstrate that microgrid control systems (MCS) and battery energy storage systems (BESS) can be integrated with on-site generation at military bases to enhance the security and reliability of electric service to the base, provide ancillary services to the electric grid Independent System Operator (ISO), and generate cost savings. The demonstration will be conducted at Portsmouth Naval Shipyard (PNS), Maine.

Technology Description

This project uniquely integrates several innovative technologies to provide cost-effective solutions for military energy security. It includes a 500 kW / 125 kWh BESS to assure power quality on base during transitions from grid power to island power and provide ongoing voltage and frequency control to the ISO. A new MCS will integrate the BESS and a variety of existing on-site generation assets to implement a fast load shed scheme and interface the PNS power system into the ISO-New England ancillary service power markets. The control system includes new metering so the MCS can intelligently select the loads to shed in order to balance with available supply.

Benefits

This system will significantly enhance the energy security of PNS by maintaining power to all critical loads in the event of a loss of grid supply. Net energy costs will be reduced due to revenues (which may come in the form of credits to utility bills) from the provision of ancillary services to the ISO-NE grid. (Anticipated Project Completion - 2015)
