Historically in California, programs to encourage energy-efficient or renewable energy technologies provide upfront financial incentives. While the dollar amounts of these incentives are typically developed in part based on the lifecycle costs and performance of the technology in question, very few have provided incentives based on the ongoing performance of the project. And none of them have based payments on the amount of carbon dioxide equivalent reduced – carbon performance. This post describes recent developments in pay-for-performance programs and a program recently approved by the California Public Utilities Commission (CPUC) that pays for carbon performance.
Paying for Energy Performance
Energy programs in California have provided an upfront financial incentive based on the expected performance of a technology or strategy. Think rebates for efficient appliances or rooftop solar photovoltaics. You purchase the technology and the program, typically funded by ratepayers, provides you a lump sum of cash. The idea is to entice energy customers to adopt the efficient or clean technology by reducing the upfront cost hurdle. Performance-based incentives, on the other hand, are based on the actual performance of the technology. One example of this type of incentive was the Self-Generation Incentive Program’s (SGIP) performance based option, but the installation of smart meters, rise of data analytics, and updated monitoring methods have provided an opportunity to employ performance-based incentives more widely.
More recently, there has been growing interest in using actual performance, measured in part by meter data, to determine the amount of incentives a project will receive. This approach is known as pay-for-performance (P4P). Several recently enacted bills have laid the statutory framework and resulting regulation to implement this concept for energy efficiency. AB 802 authorized “electrical corporations or gas corporations to provide financial incentives, rebates, technical assistance, and support to their customers to increase the energy efficiency of existing buildings based on all estimated energy savings and energy usage reductions, taking into consideration the overall reduction in normalized metered energy consumption [NMEC] as a measure of energy savings.”
SB 350 further authorized “pay for performance programs that link incentives directly to measured energy savings.” The bill specified that as “part of pay for performance programs authorized by the [CPUC], customers should be reasonably compensated for developing and implementing an energy efficiency plan, with a portion of their incentive reserved pending post project measurement results.”
There are several pay-for-performance efficiency programs implemented under the auspices of the CPUC. The PG&E Residential Pay for Performance Pilot, launched in 2016, was the first P4P program of its kind in California. Under this program, PG&E selects several aggregators through a competitive solicitation that work directly with residential customers and contractors to achieve energy savings through retrofits. PG&E provides incentive payments to aggregators based on analysis of each participating customer’s metered energy consumption.The SoCalREN Public Agency NMEC Programand BAYREN Small and Medium Businesses Pay-for-Performance Programalso use a P4P approach.
While P4P programs hold promise to expand the reach of energy efficiency programs by providing flexibility and creating an efficiency marketplace of sorts, they may not encourage the type of integrated solutions that combine efficiency, demand response, onsite renewable generation, and storage that align with customer needs and may be needed to help California reach its 2045 goal of carbon neutrality. One way to facilitate this integration is to normalize all activities using carbon dioxide equivalent as a common metric.
Paying for Carbon Performance
While the P4P programs highlighted above seek energy reductions, the CPUC recently approved a pilot program to pay for carbon reductions.The Clean Energy Optimization Pilot (CEOP), proposed by the University of California System and Southern California Edison, “will be the first program proposing to provide incentive payments directly for GHG emission reductions, rather than for gas or electricity savings or directly for equipment.”
Under the program, participating campuses (UC Davis Veterinary Lab, UC Irvine Medical Center, UC Irvine, UC Los Angeles Medical Center-Santa Monica and UC Santa Barbara) would determine a baseline GHG emission level and then, using metered data for electricity and natural gas usage, estimate annual GHG reductions from actions taken by UC campuses. The program will use GHG emission factorsand previously determined marginal GHG abatement coststo determine incentive amounts.
While the devil is in the details when it comes to estimating carbon dioxide emissions from energy reductions and renewable energy, one benefit of using CO2e as the metric is that it normalizes benefits across different project categories (e.g., renewable energy generation, storage, efficiency, etc.) and energy sources (e.g., natural gas and electricity). According to the CPUC decision authorizing the pilot, UC plans to implement a range of energy projects, including:
- Energy efficiency, including building and lighting retrofits, operational, maintenance and behavioral initiatives;
- Smart load growth, and new construction;
- On-site renewables and energy storage;
- Electric Vehicle (EV) charging installations and electrification of bus fleets; and
- Building electrification and fuel switching.
Nothing prevents these types of projects from being developed without the CEOP, but each element may be funded by different pots of money and governed by different program procedures, which can increase transaction costs. In the case of CEOP, the ability to integrate different types of energy projects into a single program was permitted because the program is funded from revenue from allowances under the state’s Cap-and-Trade Program. Under the program, “the investor-owned utilities receive an allowance allocation on behalf of all customers of the distribution utility, which includes direct access (DA) and community choice aggregation (CCA) customers. The investor owned utilities subject to the [CPUC]’s jurisdiction must consign all of their directly allocated allowances to auction with the proceeds to be used for the benefit of all ratepayers, including DA and CCA customers.” The CPUC has discretion to allocate up to 15% of GHG allowance proceeds for energy efficiency and clean energy projects.
The UC acknowledged the benefit of the integrated nature of the program, stating “there are currently no programs that specifically focus on comprehensive GHG reduction in support of the UC Carbon Neutrality Initiative.” The CPUC noted that the CEOP seems to provide the UC a program option that is better aligned with their carbon reduction goals than historical programs by emphasizing GHG reductions instead of energy reduction.
California spends billions of dollars annually to encourage energy efficiency, self-generation and energy storage technologies, and electric vehicles. Finding ways to encourage integrated projects, reduce project transaction costs, and reduce GHG emissions are laudable goals. The CEOP program appears to be an innovative way to do this. Only time and evaluation will tell whether it succeeds and can be scaled beyond the UC system. We all should keep an eye on this program to see if it can be a model for additional program reform.
