Spatial and Temporal Variation in the Value of Solar Power across U.S. Electricity Markets

Researchers combine electricity prices, emissions rates, and weather data to map the changing value of PV at ~10,000 locations across the US. Cost declines are found to have outrun value declines, such that the energy, capacity, health, and climate benefits of PV outweigh utility-scale PV costs at the majority of locations modeled.

Decentralized Economic Dispatch for Radial Electric Distribution Systems

Innovative methods for dispatching power at the residential level must be explored as more DERs are entering the market. This CEEPR Working Paper explains how power dispatching works today, and introduces an alternative, decentralized method that accounts for DERs such as rooftop solar and electric vehicles.

On the Efficiency of Competitive Energy Storage

FERC recently issued Order 841, which is intended to open wholesale energy markets to merchant storage providers. In this Working Paper, Prof. Richard Schmalensee explores the validity of the Order's presumption that existing markets will provide at least approx. optimal incentives for investment in both storage and generation: it does not contemplate the establishment of new markets or new policies.

Optimal Commodity Taxation with a Non-renewable Resource

When governments need to raise public revenues, they should tax non-renewable resources more than regular commodities according to a dynamic rule. For carbon resources, that means augmenting the carbon tax in a way that further reduces their development and slows down their exploitation, which goes further in the direction of resolving the climate problem.

Shared Capacity and Levelized Cost with Application to Power-to-Gas Technology

Power-to-Gas could become a central enabler of the transition towards a sustainable economy by reversibly converting electricity to hydrogen. A new paper shows that it will be competitive with fossil-based energy sources so as to solve the challenges of intermittent renewable generation and widespread industrial decarbonization.
