E3's recently released "Full Value Tariff Design and Retail Rate Choices" Report, sponsored by New York State Energy Research and Development Authority Department (NYSERDA) and NY Department of Public Staff, proposes a practical 'full value' tariff (FVT) and explores transition paths that can be used for its implementation. To evaluate the effects of a FVT, a New York-specific 'smart home' model was developed to evaluate customer behavior and the value proposition of key DER technologies that can potentially respond to dynamic prices sent through retail rates such as those under existing default rates, existing time-of-use (TOU) rates, and the proposed FVT or 'smart' rates that are more area- and time-specific. Solar PV, air conditioning energy efficiency, customer conservation, smart heating/cooling, and smart charging of electric vehicles were all evaluated.

E3 recently completed an assessment of the flexibility of the generation fleet of the Western Interconnection under a range of renewable penetrations. The full report and executive summary can be accessed here The study examines the operational consequences of continuing to add variable renewable resources (wind and solar) in excess of current policy targets, as well as strategies to mitigate the challenges that arise at higher penetrations. The results of the study will be shared in a webinar hosted by WECC on January 27

E3's work on technology pathways to a low-carbon energy system is having a significant international impact. E3 chief scientist Dr. Jim Williams is director of the Deep Decarbonization Pathways Project (DDPP), a consortium of researchers that has developed low-carbon blueprints for each of the 16 highest-emitting countries. The importance of this work in moving the international climate policy discussion toward concrete solutions was highlighted in a featured article in the New York Times during the recent UN climate summit in Paris. The DDPP's example had a strong influence on the Paris agreement itself, which calls for all countries to develop deep emission reduction strategies and share them transparently.

The DDPP research team for the US, led by E3 in collaboration with scholars from UC Berkeley, Lawrence Berkeley Lab, and Pacific Northwest National Lab, has produced an influential two-volume study of decarbonization pathways in the US. This study is the basis of a macroeconomic analysis by ICF International showing the potential benefits of deep decarbonization for the US economy, and was also cited by the Union of Concerned Scientists in a recent open letter to US presidential candidates urging aggressive action on clean energy.
