California is racing to electrify home heating and hot water, with state leaders backing a goal of installing 6 million heat pumps by 2030 as part of a broader push to cut carbon pollution. Regulators and agencies are rolling out incentives, pilot programs and new rate structures to steer households away from natural gas. The same policies are landing at a moment when wildfire costs, rooftop solar subsidies and utility financing decisions are already feeding some of the highest power bills in the country, raising the risk that climate ambitions collide with affordability.
The collision is not theoretical. State regulators have ordered utilities to examine how switching from gas water heaters to electric heat pump models changes customers’ overall bills and to propose rate changes that reflect those shifts. At the same time, advocates have documented that wildfire-related spending now accounts for as much as nearly one quarter of some utilities’ revenue requirements, while a separate analysis projects billions of dollars in costs from rooftop solar incentives will be borne by customers without panels. The question for California households is whether new rebates and reforms will be enough to keep the heat pump push from turning into a power bill shock.
Net-zero plan meets a 6 million heat pump target
California’s heat pump push traces back to a statewide climate blueprint that describes the “world’s first plan to achieve net zero carbon pollution,” according to an announcement from the Office of Governor Gavin Newsom. That plan points to the California Air Resources Board’s 2022 Scoping Plan and explicitly sets a target of 6 million heat pumps by 2030 as part of broader housing and electrification goals, according to the governor’s office. The same announcement links the net-zero strategy to large-scale changes in buildings, transportation and energy systems, putting residential equipment like heat pumps in the middle of a statewide emissions overhaul.
To turn that target into programs, regulators have built a web of proceedings and pilots focused on building decarbonization. The California Public Utilities Commission maintains a curated hub on Building Decarbonization that pulls together key decisions, including funding references for the TECH initiative and actions in the Self-Generation Incentive Program for heat pump water heaters. That hub also documents instructions for utilities to study how customers’ net bills change when they move from gas water heating to electric heat pump water heaters and to propose rate adjustments tied to those findings. The structure shows that affordability is being treated as an explicit design question inside the decarbonization agenda, not an afterthought.
TECH Clean California and SB 1477 set the pace
The main vehicle for scaling up heat pumps statewide is TECH Clean California, which is described as a program under California Climate Investments with a specific focus on a statewide heat pump push. The program’s description states that TECH Clean California aims to support the installation of heat pumps across the state and explicitly cites a goal of 6 million heat pumps by 2030, according to the TECH Clean California program page. That same description notes that TECH targets equity and that its governance is under the California Public Utilities Commission, indicating that regulators are trying to steer incentives toward lower-income households while still keeping the program aligned with broader ratepayer and climate policy.
TECH’s roots lie in Senate Bill 1477 from the 2017–2018 legislative session, which established the BUILD and TECH pilot program structure. An index page maintained by the Primary CPUC for the SB 1477 BUILD and TECH pilots links directly to Decision D.20-03-027 and explains that D.20-03-027 is the foundational decision establishing these building decarbonization pilots, according to the CPUC pilot program history. That decision and index show how the legislature and regulators built early funding and implementation parameters that later scaled into the current statewide heat pump campaign, including coordination with other building programs and ratepayer-funded incentives.
Federal IRA rebates stack on top of state incentives
California is not relying only on state funds to move households to heat pumps. New residential energy rebate programs funded by the federal Inflation Reduction Act are launching in the state, according to the California Energy Commission. The agency’s announcement explains that these federally funded programs include heat pump rebates and that early funds will be distributed through TECH Clean California, according to the Energy Commission. That structure means federal dollars will flow through an existing state program that already emphasizes equity and a 6 million heat pump goal, potentially amplifying the reach of both efforts.
The same Energy Commission filing trail includes a document in the commission’s electronic docket that was discovered via the Building Decarbonization hub and lays out additional detail on building programs. That document, available through the commission’s e-filing system, is linked as GetDocument and anchors some of the technical and budget assumptions behind California’s building initiatives. Together with the federal rebates, these materials show a layered incentive stack: ratepayer-funded pilots like BUILD and TECH, statewide climate investments, and Inflation Reduction Act rebates all pushing in the direction of electric equipment. The financial help is substantial on paper, yet it still operates against a backdrop of rising electricity costs that can blunt the appeal for households weighing monthly bills.
Wildfire costs and solar subsidies inflate power bills
One of the biggest pressures on those bills is wildfire spending. An analysis by the Public Advocates Office at the CPUC examines 2023–2024 wildfire-related cost increases for California’s three major investor-owned electric utilities and finds that wildfire-related cost recovery is authorized in rates for those IOUs. According to that consumer advocate analysis, the share of each utility’s revenue requirement tied to wildfire-related costs ranges from approximately 10 percent to 24 percent, depending on the company. Those figures mean a significant portion of what customers pay each month is already committed to covering wildfire mitigation, insurance and related expenses before any new electrification load is added.
Rooftop solar policy adds another layer. A fact sheet from the same Public Advocates Office provides a statewide estimate of cost shifting associated with net energy metering and projects that rooftop solar incentives will cost customers without solar an estimated 8.5 billion dollars by the end of 2024, according to the NEM cost shift methodology. That document includes an Excel methodology that details how the estimate was calculated. The combination of wildfire surcharges and NEM-related cost shifts means that households who do not have solar panels and who are being asked to electrify with heat pumps are already carrying a substantial share of system costs, which can make additional electric usage feel like a financial risk even when the equipment itself is subsidized.
CPUC reforms try to blunt the bill shock
Regulators are trying to reshape utility rules so that electrification does not always require expensive panel upgrades or new gas infrastructure. An authoritative announcement from the CPUC on customer-focused reforms describes actions to advance building decarbonization by authorizing funding for service upgrades for income-qualified customers, promoting meter socket adapters and similar alternatives to avoid full upgrades, and setting data and tariff requirements to support new electric uses, according to the CPUC reforms. Those steps are intended to cut the up-front cost barriers that often block low-income households from installing heat pumps, which in turn affects who can benefit from federal and state rebates.
At the same time, the CPUC has moved to eliminate the last remaining utility subsidies for new construction of buildings that use natural gas. An official summary explains that this change translates Decision D.23-12-037 into plain-language terms and sets an effective date of July 1, 2024 for ending those subsidies, with actual-cost billing for natural gas beginning January 1, 2025 and an annual reporting requirement starting May 1, 2024, according to the Official CPUC explanation. By shifting new buildings away from subsidized gas hookups and toward paying the actual cost of gas infrastructure, regulators are signaling that long-term planning should assume more electric equipment and less new gas demand, which aligns with the heat pump target but also changes how costs are distributed between future gas and electric customers.
Rates, cost of capital and who pays for electrification
Rate design is another front in this affordability fight. On May 9, 2024 the CPUC approved a new billing structure that changes how customers are charged for electricity. In that decision, regulators stated that “this new billing structure puts us further on the path toward a decarbonized future, while enhancing affordability for low-income” households, according to a CPUC billing document. The structure is intended to make bills more manageable for lower-income customers even as electrification increases total electric use, which is central to keeping heat pump adoption politically and socially acceptable.
Behind the scenes, the commission has also set cost-of-capital parameters for the state’s largest energy utilities for the 2026 to 2028 period. A primary announcement describes how the CPUC established authorized returns on equity and other cost-of-capital metrics that feed into each utility’s revenue requirement and ultimately into customer bills, according to the Primary CPUC decision. Those financing choices interact with wildfire spending, NEM cost shifts and the capital needed for grid upgrades, shaping how much of the electrification buildout is paid through higher volumetric rates versus other charges. If returns on equity and wildfire costs remain high, even well-designed heat pump rebates could leave households facing larger monthly bills once they switch from gas to electric heat.
The commission’s own proceedings show how these threads come together. A proceeding record related to building decarbonization reforms, accessible through a CPUC applications portal, lists R.19-01-011 and other docket details that tie rate design and customer protections to electrification programs, according to the CPUC proceeding. Another program page at the Energy Commission describes the Building Initiative for Low Emissions Development, or BUILD, which was discovered through the Building Decarbonization hub and sits alongside TECH as part of the SB 1477 family, according to the BUILD program. These records show a policy machine that is trying to manage both climate goals and customer bills, yet they also reveal a structural tension: many of the same ratepayers being asked to install heat pumps are already paying for wildfire mitigation, rooftop solar incentives and utility capital costs.
California’s bet is that carefully designed rates, targeted rebates and building rules can keep that tension from boiling over. The Building Decarbonization hub, the SB 1477 pilots and the Inflation Reduction Act rebates all treat heat pumps as central to the state’s net-zero plan, according to the coordinated materials from the CPUC, the Energy Commission and the governor’s office. Whether households experience those policies as a path to cleaner, more affordable comfort or as another reason their power bills feel brutal will depend on how quickly regulators can translate technical decisions on cost allocation into visible relief on monthly statements.
