How much of a commercial battery will BC Hydro cover?

For commercial batteries of 25 kW and up, BC Hydro's Energy Storage Incentive can cover up to 80% of eligible project cost (estimate). As a worked example: a $90,000 battery, minus a $72,000 incentive and about $8,800 in tax credit and write-off value, nets out around $9,200, and pays for itself in under 5 years on lower demand charges alone. Smaller batteries paired with solar use the standard rebate of $500 per kWh, up to $10,000, instead.

What's the catch on the 80% battery incentive?

A 10-year agreement letting BC Hydro draw on the battery during busy periods: a maximum of two dispatch events per day, four hours each, with rest between. Your building keeps running normally the whole time, and you keep the backup benefit. For operations that can't afford outages, BC Hydro is essentially paying for your backup system.

What are demand charges and how does a battery reduce them?

On BC Hydro's larger commercial rates, part of your bill is set by your single highest 15-minute draw in the billing period: the demand charge (around $13.83 per kW per month on the large general service rate). A battery discharges during those brief peaks so the grid never sees them. For refrigeration-heavy facilities with compressor spikes, that's a meaningful recurring saving on top of solar's energy savings.

Does solar make sense if my refrigeration runs 24/7?

Yes, round-the-clock load means everything your panels generate is consumed on-site at full value. As an estimate, a 200 kW system nets out around $130,000 after incentives and saves about $26,900 a year, paying off in about 5 years. Cold storage facilities also tend to have the large flat roofs solar arrays want.

Refrigeration never stops, and the rate it runs on rose 3.75% in 2025 and another 3.75% this April. Solar fixes your energy price at ~3.3¢/kWh (estimate); a battery cuts demand charges and backs up your coolers, with BC Hydro's storage incentive covering up to 80% of it (estimate).

What happens to your bill if you do nothing

BC Hydro commercial rates rose 3.75% in April 2025 and another 3.75% in April 2026. Slide to your current monthly bill and see where the compounding takes it if increases continue at a similar pace.

Estimates. Assumes increases continue at 3% per year, in line with the assumptions behind the worked examples on this page; the last two BCUC-approved increases were 3.75% per year, and future rates are set in filings you don't control. Power you generate yourself works differently: an estimated 3–5¢/kWh, fixed for 25 years, immune to every future increase. See what your version of this math looks like →

25 kW+ storage under BC Hydro's Energy Storage Incentive.

Battery cost$90,000

BC Hydro storage incentive (up to 80%)− $72,000

Tax credit + write-off− $8,800

What you actually pay~$9,200

Pays for itself in under 5 yearsOn lower demand charges alone, before counting what it's worth to keep compressors and coolers running through an outage.

In exchange: a 10-year agreement letting BC Hydro draw on the battery during peak periods: max two events a day, four hours each, with rest between. Your building keeps running the whole time.

Estimate

Rooftop solar, 200 kW

About 440 panels. Cold storage roofs are made for this.

Typical monthly BC Hydro bill, this size~$2,500 – $6,000+/mo

System cost$370,000

BC Hydro incentive*− ~$115,000

Federal tax credit (refundable)− $76,500

Year-one tax write-off value− $48,000

What you actually pay~$130,000

Saves ~$2,240/month (~$26,900/year) on powerPaid off in about 5 years. Your solar power costs ~3.3¢/kWh vs ~12¢ from BC Hydro at this size, and 24/7 refrigeration consumes every kWh on-site.

Estimated 25-year savings: ~$867,000. *BC Hydro sets larger-project incentives project by project. One B.C. industrial project received $875,000, about 40% of its system cost (public record).

All figures are estimates based on typical B.C. installed costs, current rates and general corporate tax treatment. Incentive totals already account for how the programs interact: the storage incentive and the standard battery rebate cannot be combined; the assessment determines which path is worth more for your site.

Two bill lines, two tools

Larger commercial BC Hydro accounts pay twice: an energy charge for every kWh consumed, and a demand charge (around $13.83 per kW per month on the large general service rate) set by your single highest draw in the billing period. Solar cuts the first line. A battery cuts the second, discharging for the few minutes your compressors stack up, so the grid never sees the peak.

24/7 base load

Round-the-clock refrigeration means every kWh your panels produce is consumed on-site at full value. Nothing exported, nothing wasted.

Peak shaving

Batteries flatten compressor spikes that set your monthly demand charge, a recurring saving on top of energy savings.

Big flat roofs

Cold storage and processing facilities typically have exactly the roof area solar arrays want.

Outage protection, subsidized

Refrigeration, cold rooms and irrigation pumps all hate power cuts, and under the storage incentive, BC Hydro is essentially paying for the backup.

The incentive stack behind those numbers

Energy Storage Incentive: up to 80% of a 25 kW+ commercial battery (estimate), paid in stages, in exchange for the 10-year grid-support agreement. Non-exporting, new equipment.
30% federal Clean Technology Investment Tax Credit: refundable, covers eligible solar PV and battery costs, for taxable Canadian corporations. Full 30% requires meeting federal labour requirements; our installs are structured to.
BC Hydro solar incentives: $1,000/kW up to $10,000 on standard systems; larger projects set project by project, up to ~40% of cost on the one public example. Since June 2026, rebates flow only through certified (HPCN) installers.
100% first-year write-off: expense the full system in year one.
No PST on solar equipment in B.C.

Under 25 kW of storage? The standard battery rebate applies instead: $500 per kWh, up to $10,000, paired with solar. The assessment works out which program leaves you further ahead.

What the assessment looks at

The free assessment reviews 12 months of BC Hydro bills to separate your energy and demand costs, maps your compressor and process load profile, checks roof capacity, and models both battery programs against your corporate structure. You see where the money actually is (energy, demand, or both) before anyone designs a system.
