Clark Public Utilities

October 2002 - Clark Public Utilities announced that Clark County will purchase green power to supply 10% of the electricity needs of all county buildings and facilities. With its purchase of 1.4 million kWh of green energy this year, the county becomes the largest participant in the utility's Green Lights program. The green power purchase will cost the county an extra $21,708 a year.

Green Lights is a voluntary program through which electricity customers can buy 100-kWh blocks of green power for an additional $1.50 each month, or 1.5¢/kWh. The utility offers the program in conjunction with the Bonneville Environmental Foundation (BEF), which assists in the development of new wind and solar projects in the region. A portion of the customer premiums will be used to develop new renewable energy projects in Clark County.

June 2002 - Energy Northwest announced the completion of a new 38.7-kW photovoltaic (PV) system that will supply a portion of the power for green pricing programs offered by Clark Public Utilities and Puget Sound Energy. Under the agreement, Energy Northwest will own and operate the system, Bonneville Power Administration (BPA) will add the power to its system mix, and Bonneville Environmental Foundation (BEF) will market "green tags" representing the environmental attributes of the solar output to utilities and other customers.

December 2001 - Clark Public Utilities, a public utility district that provides electric service to more than 155,000 customers throughout Clark County, Washington, has received approval from its board to offer a green power option beginning in January. Through the utility's Green Lights program, customers will be able to buy 100-kWh blocks of green power for an additional $1.50 each month, or 1.5¢/kWh. There is no limit to the number of blocks that can be purchased and there is no minimum period of participation required. The utility is negotiating with the Bonneville Environmental Foundation (BEF) to purchase power from new wind and solar projects in the region to supply the program. BEF will also help market the power and has promised to invest in local renewable energy projects in the community.

Under a law enacted earlier this year, all Washington-based utilities are required to offer a green power option to their customers beginning in 2002.

March 1998 - Clark Public Utilities (Washington) implemented a one-year program, Powerful Choices, in which about 6,000 customers (2% of the customer base) were able to choose the source of the electricity they purchase. The four power supply options offered were: (1) the current mix from Clark, (2) power from the Bonneville Power Administration, (3) green power, and (4) a market-priced option. Customers could also choose to purchase more than one type of power supply, with a minimum of 25% from each source. The green power consisted of a mix of existing geothermal and new windpower provided by PacifiCorp and was priced at 5.7¢/kWh compared to 4.2¢/kWh for the existing utility mix. Overall, only 17 participating customers (0.3%) chose to receive the 100% green power option; nearly 95% stayed with the existing mix.
