Renewables Sector: Wind Power

~ Colorado

WindSource: A Green Pricing Program
for Marketing Wind Power

As part of an effort to encourage clean and renewable energy, the Land and Water
Fund of the Rockies (LAW Fund), a nonprofit organization, has developed a
grassroots, community based approach to marketing wind power to residential,
commercial/industrial, governmental, municipal, and rural customers in Colorado.

The project, known as the Grassroots Campaign for Wind Power, is a joint effort
with the Public Service Company of Colorado (PSCo). The project is an example of
green pricing—or charging consumers slightly higher prices for an environmentally

preferable product. In this case, consumers can purchase wind-generated electricity in blocks of 100 kWh for a
$2.50 a month premium. There are also wholesale consumers who buy bulk quantities of wind-generated
electricity and sell it to their own customers for a similar premium. By developing innovative and aggressive
marketing techniques, the LAW Fund has achieved enormous success in aggregating demand for clean power
among Colorado's electricity customers.

Results:

Approximately 50 MW of wind power is expected
to be on line in Colorado by the end of 1999. Of
this amount, 25 MW is to be installed for all PSCo
customers as part of a regulatory agreement and
the remainder is a direct result of green-pricing
demand. In total, 350 businesses, 49 public
sector groups, 3 wholesale utility companies, and
approximately 17,000 residential customers have
made a commitment of over $1 million to
purchase 49,117 MWh of wind power annually. This level of demand for wind power will reduce emissions of
carbon dioxide by 44,100 metric tons (12,030 MTCE*) each year. Annual S02 and NOx emissions will be reduced
by 122 metric tons** and 109 metric tons** respectively. The community-based marketing plan has had a
significant impact on customer response to green pricing. Boulder County (where the campaign was
concentrated) represents only 5% of PSCo's customer base, yet almost 40% of total wind power purchases and
90% of the small business purchases are from Boulder County.
