A Battery Energy Storage System (BESS) collects energy from the electrical grid and then discharges that energy later to provide electricity when needed. This is like charging your phone while you sleep so you can use it when it is most needed.
ACCIONA Energía is developing the Lakeshore Batery Energy Storage System (BESS) project in response to a request for proposals issued by the Independent System Operator (IESO), the coordinator and integrator of Ontario’s electricity system.
The Lakeshore facility is in Essex Municipality, Ontario and will feature a maximum proposed capacity of 300MW/1,200MWh (4-hour storage). The standalone battery storage facilities in this portfolio will supply power and ancillary services to the IESO, which manages the transmission, distribution and commercialization of electricity for approximately the Province of Ontario.
Battery energy storage systems (BESS) allow excess energy generated from clean, intermittent sources to be captured and released during demand peaks or system disturbances, allowing energy to be injected into the grid upon demand.
In addition, these systems contribute to reinforcing grid stability and improve energy security, offering a solution to unforeseen or exceptional situations that may impact the local electric grid.

FAQs
What is a Battery Energy Storage System?
Can storage work with all fuel sources?
Yes, energy storage systems are fuel neutral. The BESS can charge from electricity generated by any fuel source. However, when BESS is charged with renewable energy it moves us closer to meeting emissions reduction goals.
What are the benefits of BESS?
Storage systems support a more efficient and resilient electrical grid, which produces a variety of benefits for consumers, businesses and communities. Some of these benefits include reduction of outages and increased grid resilience, reduces costs by storing energy when prices are low and discharging during periods of high demand, supports a sustainable grid and supports local economies.
How long do storage systems last?
Battery life depends on usage and can last for up to 20 years. Batteries can degrade based on numerous factors such as number of charge and discharge cycles and the temperature of the environment the batteries are exposed to. However, to compensate for this degradation, batteries can be replaced as part of a larger maintenance program.
What happens to the batteries at end of useful life?
A large portion of the battery can be recycled for future use in new batteries. Many of the metals used in the battery hold their value beyond the life of the battery.
