Colorado Utility Regulators Are Putting a Dollar Value on Carbon Emissions’ Impact and Will Ask Xcel to Account for It
Colorado utility regulators have waded into new political and economic waters with a vote that requires the state’s largest utility to put a dollar figure on the impacts from carbon emissions tied to future power sources. In the next few years, when Xcel next assesses how it plans to meet demand, a new coal-burning plant will be nearly impossible to justify and it will make natural gas turbines less competitive against wind, solar and other power generation sources with zero emissions.

National Grid, GE, 3M Make Power Grid Greener With Gas-Insulated Switchgear
National Grid, working with GE Grid Solutions and 3M, has commissioned gas-insulated switchgear using an alternative to sulphur hexafluoride (SF6). Used around the world for decades, SF6 is a powerful insulation gas that allows high voltage electricity switchgear to take up less space. However, while leakage rates are extremely low, SF6 is also a potent greenhouse gas, 23,900 times worse for the environment than carbon dioxide.

Disappearing Demand is a Real Issue for New Infrastructure Projects
After six years of analysis and public involvement, the Bonneville Power Administration (BPA) announced in May that that it is cancelling the I-5 Corridor Reinforcement Project, which involved more than 79 miles of 500-kV line at an estimated cost of $460 million. In its announcement cancelling the project, BPA cited non-wire alternatives including grid management and energy storage options as the most economical alternative. Administrator Mainzer stated, “The outcome is much bigger than a decision to build or not build this line: We are transforming how we plan for and manage our transmission system and commercial business practices region-wide.”
