EV Program Regulatory Support | AEP Ohio, 2017

To support AEP Ohio’s program application to the Public Utilities Commission of Ohio (PUCO), in which the company sought to install 1300 electric vehicle charging stations over four years, E3 performed a cost-benefit analysis of plug-in electric vehicle (PEV) adoption in the company’s service territory. To do this, E3 developed a statewide PEV adoption forecast and estimated costs of PEVs and charging stations as well as the electric grid costs of serving PEV charging loads. E3 also quantified the benefits of PEV adoption, which primarily result from reduced gasoline and vehicle maintenance costs. E3’s analysis — which found net benefits of $1,600 per vehicle in Ohio, and utility ratepayer benefits of $1,470 per vehicle — provided credible, independent support for AEP Ohio witness testimony.

Electrification of Transportation (EoT) Strategic Roadmap | Hawaiian Electric Companies, 2017-18

E3 provided the Hawaiian Electric Companies significant support in developing an industry-leading “Electrification of Transportation Strategic Roadmap,” filed in 2018, which outlines key utility initiatives and partnerships designed to realize economic and environmental benefits associated with EVs. In formulating and drafting the Roadmap, E3 developed a rigorous, data-driven approach to identify high-impact utility actions to promote EV adoption, minimize costs and grid impacts, and capture maximum benefits for utility customers. The Roadmap quantifies the significant benefit that EVs are predicted to provide to ratepayers and the state’s economy between now and 2045: up to $1,800 and $2,700 per vehicle, respectively, if more vehicles charge during periods of solar abundance. EVs will also support Hawaii’s ambitious goal of 100% renewable energy by 2045, provide significant CO2 reductions and local air quality benefits, and substantially reduce reliance on imported oil. Near-term priorities include: 1) customer outreach and education; 2) partnering with third parties to build critical charging infrastructure; 3) supporting customers’ transition to electric buses; 4) aligning EV charging with grid needs; and 5) coordinating with ongoing grid modernization efforts.

Deep Decarbonization in a High Renewables Future: Updated Results from the California PATHWAYS model | CEC, 2015–2018

This project evaluates long-term energy scenarios in California through 2050 using the California PATHWAYS model. These scenarios investigate options and costs to achieve a 40 percent reduction in greenhouse gas emissions by 2030 and an 80 percent reduction in greenhouse gas emissions by 2050, relative to 1990 levels. Ten mitigation scenarios are evaluated, with each […]


Modeling California’s 50 Percent Renewables Portfolio Standard

In early 2013, California’s five largest electric utilities needed to find out how grid operations would be affected if the state increased its Renewables Portfolio Standard (RPS) to 50 percent by 2030. They turned to E3 to examine operational and cost implications, explore how the utilities could reach the 50 percent RPS goal, and assess […]

Investigating a higher RPS for California | LADWP, PG&E, SMUD, SDG&E, and SCE, 2013–14

On behalf of California’s five largest electric utilities, E3 evaluated the challenges, costs, and potential solutions for achieving a 50 percent renewables portfolio standard (RPS) by 2030. Using our Renewable Energy Flexibility Model (REFLEX), we performed detailed operational studies of power system dispatch flexibility constraints under high levels of wind and solar generation. We found that achieving a 50 percent RPS is feasible and that California’s power system can remain reliable as long as renewable resources can be dispatched in response to grid needs. Our study recommended strategies for integrating higher levels of renewables, including greater regional coordination, renewables portfolio diversity, flexible generation capacity, flexible loads, and energy storage. We found that deploying these strategies would reduce the need to curtail renewables, lowering the cost of reaching 50 percent RPS.


Regulatory strategy for EV infrastructure pilot | Southern California Edison, 2014

E3 assisted Southern California Edison (SCE) in developing the policy case for its successful application to the California Public Utilities Commission to pilot a ratepayer-funded plug-in electric vehicle (PEV) infrastructure program and education effort. Envisioned as the first phase of a five-year program, the Charge Ready initiative will accelerate the buildout of charging infrastructure by preparing host sites and providing rebates to defray the cost of charging equipment. SCE will recruit hosts in multifamily buildings, workplaces, and disadvantaged communities to ensure that charging is available to a broad spectrum of potential PEV owners. E3 provided supporting analysis, which showed that increasing PEV adoption by 2030 is essential to achieving California’s long-term GHG mitigation goals. SCE also relied on E3’s cost-benefit analysis to show that PEV adoption yields net economic and ratepayer benefits. In January 2016, the CPUC authorized SCE to proceed with the pilot program.

Feasibility and cost of potential 2030 GHG reduction goals | CARB, CEC, CPUC, CAISO, 2014

The California Air Resources Board, California Energy Commission, California Public Utilities Commission, California ISO, and governor’s office engaged E3 to evaluate the feasibility and cost of potential 2030 GHG targets. We focused on emission reduction strategies through 2030, with an eye toward meeting the state’s 2050 GHG reduction goal. Using our PATHWAYS model, we developed several scenarios that varied the mix of low-carbon technologies and the timing of deployment. PATHWAYS is a stock-and-flow model that encompasses the entire state economy with detailed representations of the building, industrial, transportation, and electricity sectors. E3 team members briefed Gov. Jerry Brown and members of the legislature on the results. Our work informed the governor’s Executive Order B-30-15, which calls for a 40 percent reduction in statewide GHG emissions by 2030 relative to 1990 levels. California agencies are using our results in ongoing implementation analysis of the state’s climate goals.


Transportation electrification assessment | CalETC, 2014–16

E3 analyzed the grid impacts of charging light-, medium-, and heavy-duty electric vehicles (EVs) for the California Electric Transportation Coalition (CalETC), a consortium of automakers and utilities. To quantify the distribution system upgrades needed to accommodate residential charging of light-duty EVs, we mapped vehicle registration data with utility distribution system and load data for more than 81,000 circuits and feeders and 2,200 substations; we then modeled costs under different rate and charging scenarios.

Even with clustered EV adoption, distribution impacts were modest, and we found that managed charging reduced distribution upgrade costs by 60 percent. For most technologies studied, we showed that EV adoption can actually reduce rates for utility customers while providing net economic, environmental, and societal benefits for California. CalETC’s member utilities used our study to educate regulators and stakeholders about the benefits of EV adoption prior to seeking authorization to invest ratepayer funds in charging infrastructure and customer outreach.
