Utility customers participating in green pricing programs that offer some form of protection from fossil-fuel price changes are finding that their green power premiums are shrinking or even turning negative. For example, as of November 1, Colorado customers participating in Xcel Energy's Windsource program are paying 0.66¢/kWh less for wind energy than for "regular" electricity because of an increase in the utility's energy cost adjustment (ECA). Since the ECA announcement, Xcel has sold out of its remaining available wind energy supply and has established a waiting list for new program signups.
In Oklahoma, OG&E Electric Services customers purchasing the OG&E Wind Power product now pay 0.13¢/kWh less for wind energy than for traditional electricity and customers of Edmond Electric's pure&simple wind power program now pay 0.33¢/kWh less. Both utilities adjust their fuel charge monthly. Finally, in September, Austin Energy announced an increase in its fuel charge, which will bring the rate for its most recent GreenChoice product offering to near parity with the standard electric rate.
