Denver - Colorado Governor John Hickenlooper delivered the keynote address to the Climate Leadership Conference in Denver today, highlighting the state’s efforts to accelerate the transition to renewable energy by working with companies and municipalities throughout the state.
A glimpse of the "infinite scalability" of energy storage, and some other key takeaways from this very exciting utility bid solicitation
After I posted Xcel Energy’s report showing unprecedented low prices for renewable energy and storage bids, several energy industry experts added some helpful context and analysis of the implications of these bids.
Much of that discussion focused on the low bid prices for projects that would combine renewable energy with energy storage. The Xcel Energy report showed that the median bid price for solar and storage projects was $36/MWh, while the median bid price for wind and storage projects was just $21/MWh. There were also seven bids for combined wind and solar and storage bids, with a median price of $30.60/MWh.
"The numbers in these bids are the lowest prices we have seen for any combination of renewable plus battery storage," said Ravi Manghani, director of energy storage at Green Tech Media.
Matt Gray, Utilities & Power Senior Analyst at Carbon Tracker, added: “Based on our modelling, the median bid for wind plus storage is lower than the operating cost of all coal plants currently in Colorado, while the median solar plus storage bid is lower than 74% of operating coal capacity.”
Fraser, CO - The town of Breckenridge passed a resolution last week establishing a goal to power the community with 100% renewable electricity by 2035. Breckenridge joins other Colorado towns and cities that are pursuing 100% renewable energy, including Pueblo, Boulder, and Nederland. Aspen achieved its 100% renewable energy goal in 2015, while other towns and cities including Denver and Durango are also considering renewable energy goals.
The responses from the utilities that serve those Colorado towns and cities show that these 100% renewable energy goals are helping push the region toward a cleaner electricity grid, achieving a broader impact than sustainability goals that remain within the boundaries of a municipality. That’s consistent with a new report by global management consulting firm McKinsey & Company, which argues that cities should focus their sustainability efforts on four strategic areas for maximum impact. First among those four strategic areas is using their position as major electricity consumers to help decarbonize the electricity grid:
While cities may believe they have little influence over the grid mix, in fact, they often represent a major portion of any local electric utility’s customers, potentially giving them significant leverage to shape the emissions profile of the electricity consumed within their metropolitan area. Still, capturing this opportunity will not be easy, and cities cannot do it alone. Utilities and regulators must play a central role in ensuring the overall mix of renewables is appropriately balanced at a system level and that critical components such as energy storage are in place to ensure grid reliability. Nevertheless, cities have an essential role to play by setting clear decarbonization goals, aggregating demand for renewables, promoting energy efficiency, and shifting more urban energy consumption to electricity (especially in transportation and heating).
Lowering the emissions intensity of the electricity grid is an especially impactful way that municipalities in the Rocky Mountain region can advance their sustainability goals, because the region’s grid is more dependent on coal, and therefore more carbon intensive, than other parts of the US. But as these Colorado towns and cities seek to accelerate the transition to renewable energy, they face varying challenges in working with the different utilities and electric cooperatives that sell electricity in Colorado. Colorado towns and cities are served by two investor owned utilities, 29 municipal utilities, and 22 rural electric cooperatives, according to the Colorado Energy Office
Let’s look at four Colorado municipalities pursuing renewable energy goals, each with a different electricity provider: Breckenridge, Pueblo, Aspen, and Durango.
Mead, CO - Next week, United Power will switch on its biggest solar project yet. At 16 megawatts, the SR Platte solar array will produce enough electricity to power 2,700 homes, and help the electric cooperative save money on its electricity purchases.
But because of its contract with its electricity supplier, Tri-State Generation and Transmission, United Power is unlikely to build more solar arrays any time soon, so it's shifting its focus to energy storage.
