New Colorado law doubles renewable energy standard

SAN FRANCISCO (Reuters) - Colorado utilities will have to get 20 percent of their electricity supply from renewable energies by 2020 under a bill signed into law on Tuesday by Gov. Bill Ritter.

The measure doubles Colorado’s renewable energy requirements for more resources such as wind, solar and geothermal power.

The new law also requires municipal utilities and rural electric cooperatives to meet a renewable energy standard of 10 percent by 2020.

Ritter, a Democrat, also signed into law a bill to streamline development of more capacity on the state’s transmission grid.

The law will allow utilities to recover the costs of new transmission projects during construction.

A recent Colorado study said the state will need about 4,000 more megawatts to meet power demand by 2015 which will require a $2 billion investment in new transmission lines.

About half of the 50 U.S. states have adopted guidelines or rules for the share of renewable power delivered to utility customers.

Colorado was the first state whose voters passed a renewable standard in 2004.

Coal is the largest fuel for power generation in Colorado, followed by natural gas.
