Representative Engagements
Measurement and Verification
Measured the impacts of a system-wide Time of Use (TOU) deployment in the province of Ontario, Canada, on behalf of the Ontario Power Authority. To account for the lack of a designated control group, we created a quasi-experimental design that took advantage of differences in the timing of the TOU rollout.
Rate Design and Related Issues
Redesigned and rebuilt several marginal cost and rate design models for a large Californian utility. The new model designs reduced regulatory risk and increased analytical abilities and flexibility by taking advantage of utility investments in data collection and advanced software systems.
Innovative Pricing
For the Australian Energy Market Commission (AEMC), developed a report that reviews the various forms of dynamic pricing, such as time-of-use pricing, critical peak pricing, peak time rebates, and real time pricing, for a variety of performance metrics including economic efficiency, equity, bill risk, revenue risk, and risk to vulnerable customers. It also discusses ways in which dynamic pricing can be rolled out in Australia to raise load factors and lower average energy costs for all consumers without harming vulnerable consumers, such as those with low incomes or medical conditions requiring the use of electricity.

The public benefits of leasing energy efficient equipment
July 2017
Ahmad Faruqui, Neil Lessem, and Henna Trewn
Published in The Electricity Journal, Volume 30, Issue 6
Utility-led leasing solutions can overcome several key barriers to customer adoption of new, efficient products that are overlooked by traditional energy efficiency programs or non-utility leasing programs, as a program proposed by Puget Sound Energy illustrates. By encouraging the installation of energy efficient equipment, a utility-led leasing program would generate significant benefits in terms of bill savings, enhanced comfort and quality of life, avoided energy costs, avoided capacity costs, and avoided emissions.
