The coal power sector in the US is continuing to shrink due to poor economics, but this doesn’t mean we’re retiring coal fired power plants quickly enough to reduce carbon emissions at a rate that achieves our climate goals. So what’s the best way to get rid of coal plants before they reach the end of their expected lifespans, particularly while the Trump administration and the Republican party continue trying to find ways to keep coal plants open? Democratic state Representative Chris Hansen of Colorado has proposed a solution: Refinancing the debt that utilities still owe on their coal-fired plants with cheaper, public bonds, and then shutting down the plants. It’s an idea that would retire coal plants and reduce carbon emissions, save utility customers money, create better investment opportunities for the utilities, and replace that power with cheaper, clean, solar and wind power. Everybody wins! It’s a powerful idea whose time may have come in Colorado, where fossil fuels still make up 78% of the state’s electricity mix, and major utilities in the state, like Xcel Energy, have declared their intention to transition to 100% clean power in the coming decades. Will Hansen’s bill have the right approach to help achieve those goals? We dive into all the important details in this episode and find out!
This one is for the grid geeks! With the Green New Deal now a hot topic in the US Congress, while wholesale power markets still struggle to figure out how to accommodate new kinds of resources even as coal plants and nuclear plants continue to retire, the question of how wholesale power markets should work, and how they should value new kinds of assets and services, is becoming increasingly urgent. What would a power market look like if it consisted mainly (or totally) of wind and solar, with their zero-marginal-cost power? And if we continue to use out-of-market payments to keep clean but uneconomic nuclear plants operating, what will be the effect on power markets? Will power markets ultimately crash under the weight of accumulated patches and workarounds, or can their design be adapted to new social priorities—like combating climate change—and new kinds of resources, like large-scale storage systems? Can we replace the market construct of locational marginal pricing with something more suited to the new reality of grid power? What kind of policies can keep us on track to support transition and facilitate the evolution of the fuel and technology mix toward a high renewables future? Will FERC Order 841 succeed in opening the doors to storage on the grid? Are real-time prices the future of rate design? And as we move toward a deeply decarbonized grid, what are the implications for our economic system?
In this episode, we delve into all those questions and more with an expert who has worked on power markets for over 30 years.
Ireland is one of the most advanced countries in energy transition, getting over a quarter of its electricity from renewables. It also has one of the most ambitious targets—to obtain 40% of its electricity generation from renewables by 2020—and the resources to be more than 100% powered by renewables, given time and technological development. On the flip side, it also has a severe dependence on imported fossil fuels, and relies on some of the dirtiest power plants in the world.
In this episode, we explore this curious mix of reality, ambition, and potential with the leader of Ireland’s Green Party, a bona fide energy wonk and a longtime supporter of energy transition. From Ireland’s domestic renewable resources to the tantalizing possibility of the North Seas Offshore Grid initiative, it’s all here.
