From The Pueblo Chieftain (Chris Woodka):
The water board spends about $2.2 million on electricity each year, or about 7 percent of its $30 million budget. Energy costs could increase by $1.2 million annually with proposed rate increases, said Terry Book, deputy executive director. The water board has a 20-year-old plan to retrofit its water line from Pueblo Dam for hydroelectric generation, but it was not economical to build it in the past. The cost to install it in 1990 was $4 million, and the price of selling it to the power company at the time wasn’t high enough to make a deal worthwhile. Hydro would generate only 0.3-1.2 megawatts of electricity, which would only supply a fraction of the water board’s needs.
The water board also could look at solar panels and wind generation.
