The BESS supports the operations of the kīsikāw pīsim solar farm by storing electric energy on site and releasing this electric energy as needed for use by the Water Treatment Plant.
The BESS will have a storage capacity of 4MW/8.9MWh, activated based on the power available from the solar generating units together with the load demand at the Water Treatment Plant. For example, when the demand from the Water Treatment Plant exceeds the power available from the solar generating units, the BESS will be used to manage the load.
When energy produced by the Solar Farm exceeds what is needed for on-site self-supply, either by the Water Treatment Plant or storage in the BESS, it can then be exported back to the local power pool.
Edmonton is sunny. It is one of the leading cities in Canada for solar energy capture, and annual photovoltaic potential. EPCOR can harness the solar farm to produce the most energy possible during the spring, summer and fall months, to best align with water demand at the E.L. Smith Water Treatment Plant.
Customers today, like EPCOR are facing many complex challenges at once including energy autonomy, reliability, and resiliency; looking for new economic opportunities; and effectively managing an increased portfolio of distributed energy resources (DERs), like solar and wind. Hitachi Energy’s e-mesh™ portfolio delivers a scalable, vertically integrated digital ecosystem for managing and optimizing energy at all levels with wide range of applications from the field to the boardroom, on cloud and on premise.
