Ontario businesses can net-meter up to 500 kW and bank export credits for 12 months, or take Save on Energy's Retrofit incentive for load-displacement solar — now $770/kW-AC for systems over 10 kW. Incorporated businesses can add the 30% Clean Technology ITC either way.
Commercial net metering runs under the same regulation as homes, O. Reg. 541/05, with every local distribution company required to offer it[2]. The decision that matters for a business is whether to export for credit or to take the provincial incentive.
| Net metering | Save on Energy Retrofit (solar DER) | |
|---|---|---|
| Upfront incentive | None | $1,000/kW-DC up to 10 kW; $770/kW-AC above 10 kW (to 1 MW); max 50% of cost |
| Exports | Credited, 12-month carry-forward | Designed for load displacement |
| Size | Up to 500 kW | Incentive capped at 1 MW-AC |
| Key rule | Utility connection agreement | Apply before any binding purchase commitment |
Toronto Hydro describes the two as alternatives: a business can lower project cost either by joining its Net Metering Program or through the Save on Energy Retrofit Program for behind-the-meter solar[3]. The Retrofit stream is for load displacement and is open to commercial, industrial and institutional businesses[5]. On June 30, 2026 the incentive for systems over 10 kW fell from $860 to $770 per kW-AC[4].
Exports earn credits against electricity charges that can be carried forward for up to 12 consecutive months[1]. Demand charges are unaffected by credits, so the strongest projects also shave peak demand.
Taxable corporations and incorporated farms can claim the refundable Clean Technology ITC — 30% with the labour election, 20% without[6]. A Save on Energy incentive counts as government assistance and reduces the ITC base.
