Judge Recommends Decoupling for Xcel Energy
An  Administrative Law Judge recommended  granting  Xcel’s  request for Revenue Decoupling for residential customers, meaning cost recovery will no longer be based on how much electricity is sold.  COSEIA hopes this decision will be good news for solar development by removing a disincentive Xcel has cited to expand solar. The commission refused Xcel’s request for a weather adjustment, which was a victory for solar advocates. The recommended decision did not grant decoupling for [...]

Stranded Utility Renewables — A Competitive Challenge for Early Adopters
Figures for the deployment of utility-scale renewable energy projects in the U.S. over the past decade are truly breathtaking. Installed utility-scale wind power capacity in the U.S. has increased nearly sevenfold since 2007, reaching a cumulative level of more than 80,000 MW in 2016. Deployment of utility-scale solar has been even more impressive, reaching a cumulative level of more than 10,000 MW in 2016 from less than 160 MW in 2007. [...]

PUC Says Climate Change Impacts Need to be Considered in Resource Planning
The Public Utilities Commission written order approving Xcel Energy’s Electric Resource Plan, issued April 28,  contains important precedents that acknowledge the real costs of climate change in Colorado.  The long-range planning document  will  guide Xcel in making future resource decisions. COSEIA believes it is very significant that the PUC majority agreed with us, and others, that Xcel must model the “social costs’’ of carbon when planning on what future energy resources to acqui [...]

PV Plant Repowering, the Utility 50-Year Systems Model
There are two basic types of solar PV plant repowering. The first is for existing or distressed plants. The second is for extending the life of new plants at the end of their initial design life, which is projected at about 20 to 25 years. So as we concentrate on new plant repowering, what is the difference? [...]

Solar Power: More than half of utility-scale solar photovoltaic systems track the sun through the day
The electricity generated by a solar photovoltaic (PV) system depends on the orientation and tilt of the PV panels, and in some cases, its ability to track the sun throughout the day. Because photovoltaic panels operate more efficiently when oriented directly at the sun, some systems use solar-tracking technology to increase electricity generation by rotating the panels along one or two axes.
