Over the last year, there appears to be a resurgence in the consideration of performance-based ratemaking (PBR) in utility regulatory proceedings across the country. As advanced technologies are deployed by electric utilities pursuing broad smart grid initiatives, there is an increasing realization that traditional regulatory policies and ratemaking may be inadequate when it comes to striking the right balance between the risks associated with utility investments in smart grid technologies and the need to modernize what is clearly an aging energy infrastructure. According to a number of state utility commissions, PBR—which has been around for decades in various forms—may once again provide a solution.
For those who may be unfamiliar with the term, PBR is a fairly generic term that becomes more defined when it is applied in a specific regulatory proceeding. Although PBR can take many different forms and the application of it will be unique in each state jurisdiction, essentially PBR refers to a process by which energy utilities’ revenues are adjusted based on their performance. Under PBR, rates are set on a utility’s performance on various measures, such as reliability and customer service as well as costs. Typically, a target baseline for rates is set by a utility’s regulator and then, based on a set of established performance metrics, if the return on equity (ROE) achieved by the utility exceeds this target then the utility would provide its customers with a credit defined by an agreed-upon sharing mechanism; if the ROE falls short of the target then it would be able to seek a rate increase or other surcharge. If a utility does not meet its performance goals, the regulatory commission may seek to reduce the utility’s ROE.
There appears to be a consensus in the Energy & Utilities industry that PBR will become more prevalent and performance results will be contested more frequently as utilities continue to deploy advanced technologies. Regulators will likely seek to ensure that rates and rate increases are directly tied to measurable performance metrics, such as the reduction of frequency and duration of outages and the number of estimated billing statements. Other performance metrics might include theft detection and minimizing energy usage from inactive meters.
Last year, Illinois became the first state to approve a comprehensive PRB structure directly associated with utility investments in smart grid, through the state’s Energy Infrastructure Modernization Act (EIMA). The logic behind the legislation is to create a value proposition for sharing risks and benefits between Illinois’ utilities and their customers, while modernizing the grid. There are specific set of metrics on which Ameren and ComEd will need to demonstrate performance in future regulatory proceedings that will impact the level of their potential earnings.
In addition to Illinois, the apparent resurgence in PBR is evidenced by activities in other states:
West Monroe Partners has been following this regulatory trend closely and will be hosting a Webinar on the topic on Wednesday, March 27. The focus of the Webinar will be on the potential ineffectiveness of traditional, cost-of-service ratemaking as it pertains to current smart grid and energy efficiency projects; the primary drivers for reconsidering PBR as an alternative; regulatory and legislative PBR initiatives that have emerged in specific states; and the design and tracking of performance metrics that have become the new basis for cost recovery and earnings sharing in PBR-based regulatory proceedings.
