When Electric-Car Incentives Return: British Columbia Case Study

Christmas came in April last year for plug-in electric vehicle proponents in British Columbia, Canada, when the provincial government reinstated its Clean Energy Vehicle purchase-incentive program.

Purchase rebates for B.C. buyers of plug-in electric vehicles had ended in February 2014, when the program's funding allocated was depleted. It wasn't funded anew until April 2015.

After several months, we can now estimate the effect of the rebates' return on the province's plug-in electric vehicle sales.

B.C. car shoppers should be aware that the incentives will likely disappear again next month, as the allocated funds are again running low.

British Columbia Clean-Energy Vehicle funds as of Jan 23, 2016: $289,000 equates to about 60 cars

The Clean Energy Vehicle program offers point-of-purchase rebates of $2,500 to $5,000 for the purchase of plug-in electric vehicles, depending on the size of the battery. (The Chevy Volt's 18.4-kilowatt-hour battery is big enough to qualify for the full $5,000.)

All new-car sales qualify, regardless of the buyer's personal income or the vehicle price, or whether it was purchased from a franchised car dealer or directly from Tesla Motors.

Electric cars do not, however, get preferential access to carpool (high-occupancy vehicle) lanes. This means that the rebates only affect the purchase price, making for a straightforward analysis of their effect.

(In regions where plug-in electric vehicles qualify for both financial incentives and HOV lane access, it can be difficult to disentangle the effects of the two factors.)

Choosing the right yardstick

It would be premature to draw conclusions about the impact of incentives based strictly on monthly sales totals.

Not only is the Canadian auto market highly seasonal, but such factors as gas prices, manufacturer and dealer incentives, the health of the local economy, and the availability of new or refreshed models all influence the total number of electric vehicles sold in a given region in a given month.

To control for as many of these factors as possible, we looked at the ratio of plug-in electric vehicle sales in British Columbia to combined sales of the same vehicles in Ontario and Quebec.

Those two provinces represent about two-thirds of the Canadian electric car market and have maintained their rebate programs, so they offer the best available baseline.

Finally, because different plug-ins are targeted at different customers, separate comparisons were made for the Tesla Model S and BMW i3 (representing the luxury segment) as well as the Nissan Leaf, Chevy Volt and Smart Electric Drive (representing the non-luxury segment).

A combined Leaf-and-Volt analysis was done, to allow us to compare with the article written when the incentives first expired.

IHS Auto was the source of the monthly vehicle registration data, which do not distinguish between new vehicles and used imports from the United States. The small number of imports should not distort the trends, being less than one-tenth the number of new car sales.

No Impact of bucks For luxe

Relative to sales in Ontario and Quebec, the removal and return of purchase incentives didn't affect Tesla Model S or BMW i3 sales in British Columbia.

The i3 sold 77 percent as many vehicles in B.C. as the other two provinces in 11 months without purchase incentives, and 75 percent as many in the first eight months after their return.

B.C. sales of the Tesla Model S were 27 percent of the central Canada total in the year before the B.C. incentives expired. But during the year that incentives were gone, the proportion rose to 37 percent; it has since held steady (35 percent).

One noticeable quirk in the chart is that virtually no Tesla buyers took delivery of their vehicles last March (5 percent sales ratio) – they held off until April, when they would quality for rebates, leading to a 99 percent sales ratio between the two geographies for that month.

The numbers seem to imply that British Columbia's $5,000 purchase rebates had little effect on the adoption rates of luxury plug-in electric vehicles. By and large, we might conclude, their purchasers could absorb the full sticker price.

Dollars do drive change

But it's a different situation among buyers of more mass-priced cars. Sales ratios of the Leaf and Volt were roughly cut in half when the purchase rebates expired in 2014, and then jumped back to earlier levels when the rebates returned.

The Nissan Leaf's sales ratio dropped from 45 percent to 19 percent when incentives expired, then rose back to 50 percent since the incentives' return. (Going forward, I'll use the shorthand "45-19-50".)

The Chevy Volt's sales percent ratio over the same time period was 9-4-6. Those numbers are low, as the Volt is relatively unpopular in B.C.--but particularly popular in Quebec.
