BC Hydro is a regulated electric utility owned by the Province of British Columbia that operates as a commercial entity. It serves 1.85 million customers representing 95% of B.C.’s population. While BC Hydro has had energy efficiency programs since 1989, its current resource acquisition focus began in 2003. Its generation fleet is predominately hydroelectric and it has committed to providing 90% of its power through clean and renewable generation. It has also committed to meet at least 50% of load growth through the acquisition of energy efficiency resources.
The industrial sector represents about 30% of BC’s load, which it serves with an innovated rate structure that prices a customer’s marginal consumption higher than its recent historic baseline. To assist these customers minimize energy use, it has spent $15-25 million per year providing general awareness, education, technology demonstrations, energy assessments, energy management system training, and direct financial incentives. Cumulative savings of 2.4 TWh over four years from the recent Power Smart 3 represent 4.6% of total electric demand for the service territory.

Program Offerings for Industry:
BC Hydro’s industrial offerings are centered on their unique two-tiered "conservation rate" structure, which drives energy efficiency measures by increasing the price of the top 10% of electricity use (using a historic baseline). The other 90% of electricity is charged at a lower rate to keep the average cost the same (*4) (*5). Once available only to large customers receiving distribution-level voltage, the conservation rate is now available to medium-sized businesses (35-150 kW peak demand) as well.
To complement the conservation rate structure, BC Hydro offers its industrial customers several other initiatives:
- Audits (high level, detailed, or focused on a specific end-use)
- Feasibility studies
- Financial incentives covering up to 75% of project cost
- Energy Management training and on-line tools (*6)
- Energy assessments
- Training and educational workshops
- Awareness events
- Development of energy plans
- Funding and support of technology demonstration projects
- Support for implementation of energy efficiency codes and standards.

M&V requirements on industry:
Industrial and Commercial program measurement and verification procedures include
- a technical review, including review both before and immediately after investment;
- site inspection of a sample of projects to confirm project completion and operation as approved; and
- measurement and verification on a sample of projects to quantify individual project savings through analysis of actual project operation and performance data.

Impacts and Results
Analytic base for target (or target setting mechanism):
Savings are cumulative over all the years in the relevant program cycle. The concept can also be described as cumulative electricity savings capacity delivered and still effective by target year. It is important to note that BC Hydro needs to calculate the "persistence" of savings capacity created in previous years, based on the estimated lifetimes of the savings capacity created through the various main measures. If the lifetime of capacity has expired, it is subtracted from cumulative savings, as that capacity that had been created no longer persists. Thus cumulative energy savings (capacity) will be increasingly smaller than the sum of incremental savings (capacity) achieved each year as programs continue.
Savings (recent year):
Savings (program total):
Average unit cost of energy saved:
The cost effectiveness of the program overall has been strong at 2 cents/kWh. The industrial program provided savings at 1.5 cents/kWh, including 1 cent per kWh for large customers receiving power at transmission voltage, where savings resulted from the energy conservation rate, enabling activities and certain incentives.

(*4) Before the energy conservation rate was introduced for residential customers in April 2009, all consumption was priced at 6.55 cents/kWh. The new rate included a price of 5.91 cents/kWh for "Step 1” block consumption of up to 1350 KWh per 2-month billing cycle, and a price of 8.27 cents/kWh for "Step 2” consumption over 1,350 kWh per billing cycle.
