Monthly Bills and Average Prices as of May 1, 2011 This is the fourth Electricity Rate Comparison Annual Report (Report) prepared by BC Hydro in response to the Rate Comparison Regulation, issued by Ministerial Order No. M114, under the Utilities Commission Act, on March 30, 2009. The Report provides a comparison of BC Hydro s monthly bills and average prices for residential, commercial and industrial customers with other North American utilities, including those in Alberta, Quebec, Ontario, Manitoba, Washington, Oregon and California. 1 Each year BC Hydro participates in a Hydro-Quebec comparison survey, submitting bill calculations based on electricity prices that are in place as of April 1 of the current year, and which may reflect approved interim rate increases. Hydro-Quebec compiles the information and provides the monthly bills and average prices for 12 Canadian utilities and 10 American utilities in an annual report. The BC Hydro Report provides survey information taken from the Hydro-Quebec report: Comparison of Electricity Prices in Major North American Cities 2. The Hydro-Quebec report provides the monthly bills, excluding taxes and non-utility levies, calculated for specific consumption points for four different customer segments: residential, small power, medium power and large power. The average price is also calculated, for each customer segment and specific consumption point, by dividing the monthly bill by the amount of monthly energy consumption. For example, if an electric bill for 1,000 kwh was calculated to be a monthly amount of $50, the average price would be $50 divided by 1,000 kwh, or 5 cents/kwh. Due to the timing of its F2012 rate increase, BC Hydro has replaced its April 1, 2011 rate calculations from the Hydro Quebec report with rate calculations using its rates on May 1, 2011 to compare against the other utilities rates on April 1, 2011. 1 2 Monthly bills and average prices for American utilities have been converted to Canadian dollars using the exchange rate as at 12 PM Eastern on April 1, 2011 of CDN $0.9926 per US $1. http://www.hydroquebec.com/publications/en/comparison_prices/index.html.

BC Hydro believes that its May 1 rates provide a more meaningful comparison than those provided in the Hydro Quebec report. The monthly bills for customers are presented in Tables 1 to 4. The average prices for customers are presented in Tables 5 to 8. BC Hydro s monthly bills and average prices over the past five years are summarized in Tables 9 and 10. The Hydro-Quebec residential segment includes calculations for BC Hydro s residential customers. The Hydro-Quebec small power segment includes calculations for both BC Hydro s general service under 35 kw customers and general service 35 kw and over customers, while the medium power segment includes calculations for BC Hydro s general service 35 kw and over customers. Lastly, the Hydro-Quebec large power segment includes calculations for BC Hydro s general service 35 kw and over customers and transmission service customers. Table 11 shows the specific BC Hydro rate schedules that have been included in each Hydro Quebec segment. Table 12 summarizes BC Hydro s relative rankings in each rate class since the first year of participation in the survey in 2008. Based on the data from the Hydro-Quebec survey, BC Hydro s monthly bills and average prices for all customer segments are generally within the top quartile of utilities, with low rates providing a competitive advantage to customers in British Columbia. The rankings of the top five participating utilities with the lowest monthly bills and average prices are noted in the tables. Out of the 22 utilities providing data, BC Hydro s monthly bills and average price rankings on May 1, 2011 against the Hydro-Quebec report for April 1, 2011 data are as follows: Page 2
