COLORADO'S POWER PATHWAY - Colorado Power ...
BENEFITS
Colorado’s Power Pathway supports the state-mandated goal of an 80% reduction in
carbon emissions by 2030, which all electric utilities are required to comply with. Because
Colorado’s open transmission system carries electricity generated by multiple utilities
that is distributed to homes and businesses by local power companies, both electric
utilities and electricity users around the state benefit from this Project.

Electric System Benefits

       New transmission lines encourage         Existing transmission on the eastern
       and support the development of           plains primarily serves local needs
       renewable energy to bring more           and is nearly “full” and additional
       low-cost electricity to help meet the    transmission capacity is needed
       needs of our growing state.              to integrate more renewable
                                                generation

       Colorado’s Power Pathway supports        Colorado’s Power Pathway provides
       Xcel Energy’s Clean Energy Plan          high voltage “backbone”
       that will add approximately 5,000        transmission. A grid supported by
       megawatts of new wind, solar and         backbone transmission is better
       other resources through 2030 to          positioned to withstand outages.
       enable the state’s transition to clean
       energy
