What are DERs?
Distributed Energy Resources (DERs) are small-to-medium scale generators — like solar arrays and battery storage systems — located close to where energy is consumed. In Ontario, DERs interconnect directly to local distribution networks rather than the high-voltage transmission grid, helping utilities manage peak loads, defer upgrades, and increase resilience. By embedding generation and storage at the distribution level, communities benefit from reduced line losses, enhanced reliability, and a more flexible power system.
At Onder Renewables, we specialize in 5–10 MW front-of-meter photovoltaic solar and battery storage projects, all fully distribution-connected.
Our Technologies
-
Solar PV
A typical solar photovoltaic array consists of rows of panels that convert sunlight into DC electricity. An inverter system then transforms it into AC power, which is exported directly into the local distribution network—helping to meet peak demand, reduce line losses, and stabilize the grid at the neighbourhood level.

Battery Energy Storage Systems (BESS)
A battery energy storage system (BESS) uses lithium-ion modules to store surplus electricity and discharge it on demand. Integrated power conversion equipment manages charge/discharge cycles and grid‐forming functions, delivering frequency regulation, peak‐shaving, and voltage support directly into the local distribution feeder.
