America’s Power Plan collects the latest research on smart energy policies from the leaders in America’s power sector transformation. In addition to our blog below, we also produce periodic newsletters (sign up here) on current topics to help policymakers and other stakeholders stay up to date on important questions.

Imagine that we have built enough wind and solar power plants to supply 100 percent of the electricity a region like California or Germany consumes in a year. Sure, the wind and sun aren’t always available, so this system would need flexible resources that can fill in the gaps. Filling this gap is one of the principal flexibility challenges of a low-carbon grid. But what will that flexibility cost?
In April, DOE Secretary Rick Perry issued a memorandum to his staff asking some pointed questions about the future of the electric grid as coal is retired off the system. The DOE’s publication of this memorandum presents an opportunity to uncover many outdated assumptions and understand the drivers behind the unstoppable transition from coal to other technologies. By taking each premise in turn and providing evidence-based analysis, we can see that the projected demise of coal will result in a cleaner, cheaper, and more reliable energy system.
As the need for flexible resources grows, there will be an increasing number of bellwether events – or demand spikes due to unusual temperature changes or other events. Resource developers are likely to respond by building new resources that can capture this value on the spot market and through bilateral contracts with utilities. However, not all markets are structured to reward flexibility in the same way as in energy-only markets.
States and utilities around the country are considering new utility investments in modernizing the grid. As utilities come to the table for grid modernization funds in many states, regulators and stakeholders should start planning now to get ahead of the process and generate the most benefits from those investments. APP experts Sonia Aggarwal and Mike O’Boyle have laid out five steps utility regulators can take to ensure customers reap the benefits promised by a modern grid.
Some nuclear plants consistently in the red in competitive wholesale markets have driven some to call for re-regulation and the abandonment of a free market approach. With an aging nuclear fleet, policymakers will inevitably face decisions about how long to support existing plants and how to avoid capacity shortfalls when shutting them down at the ends of their lives. Which of these options drives a cheaper, cleaner, and more reliable electric system will vary based on context.
For years, many debates on the future of the electricity system centered on getting the balance right between higher costs and lower environmental impacts. But the economics of the renewable energy transition are rapidly shifting. It’s looking like we may not have to choose between affordability and environmental impact – a cleaner, cheaper grid may be within reach.
Back in January, I suggested 2016 was the year for wholesale power market reform. So, was it? While shifts in these kinds of institutions take longer than one year, we’ve seen real progress on the four factors that made 2016 a turning point, and we believe progress will continue in 2017. America’s electricity mix continues to churn. During this period of transition, policymakers must pay particularly close attention to proposed wholesale power market changes.
Lower costs, enhanced capabilities, and an abundance of resources have set the United States and much of the world on track to increase renewable energy deployment and decrease carbon emissions from the energy sector. Still, the question of whether the U.S. can reliably and affordably integrate large amounts of wind and solar confronts policymakers – so we’re giving you four reasons 30% wind and solar is technically no big deal.
