The electricity supply industry in a low-carbon world will have over 50 percent share of intermittent renewables.  This large share of intermittent renewables will require investments in both grid-scale and distributed storage, active demand-side participation by customers, and automated distribution network monitoring and on-site load-shifting technologies.  Market design should support business models that lead to adoption of these pricing policies and technologies.  The policy question is what long-term resource adequacy mechanism will facilitate a least-cost transition to this future electricity supply industry with these pricing policies and technologies?
