                <ns0:Title> An act to add Section 25236 to the Public Resources Code, and to add Sections 236.5, 451.10, and 719.5 to the Public Utilities Code, relating to public utilities. </ns0:Title>

                        <ns0:Subject>Public Utilities: gas corporations: duty to serve: thermal energy networks.</ns0:Subject>
                </ns0:GeneralSubject>
                <ns0:DigestText>
                        <html:p>Existing law vests the Public Utilities Commission (PUC) with regulatory authority over public utilities, including gas corporations and heat corporations. Existing law requires every public utility to furnish and maintain adequate, efficient, just, and reasonable service, instrumentalities, equipment, and facilities, as are necessary to promote the safety, health, comfort, and convenience of its customers, its employees, and the public. Existing law authorizes a gas corporation to cease providing service if a certain pilot program has been implemented and the PUC determines that adequate substitute energy service is reasonably available for the energy end uses of affected gas corporation customers.</html:p>
                        <html:p>This bill would authorize a gas corporation to satisfy its obligation to provide gas service by providing thermal energy through a thermal energy
                network, as defined, if the PUC determines that the network offers an adequate and reliable substitute for the thermal end-use energy needs of its customers. The bill would specify that a project for the construction, maintenance, or repair of a thermal energy network is a public work and would require a gas corporation undertaking the project to ensure that all contractors and subcontractors performing work on the project use a skilled and trained workforce. The bill would require to PUC to initiate a proceeding to establish a regulatory framework for the provision of thermal energy service by gas corporations, as provided.</html:p>
                        <html:p>This bill would require the State Energy Resources Conservation and Development Commission, in consultation with the PUC, to develop technical standards for thermal energy networks, as provided.</html:p>
                        <html:p>Under existing law, a violation of the Public Utilities Act or an order, decision, rule, direction, demand,
                or requirement of the PUC is a crime.</html:p>
                        <html:p>Because the labor requirements for a thermal energy network project would be part of the act and a violation of a PUC action implementing those requirements would be a crime, this bill would impose a state-mandated local program.</html:p>
                        <html:p>The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.</html:p>
                        <html:p>This bill would provide that no reimbursement is required by this act for a specified reason.</html:p>

                <ns0:Preamble>The people of the State of California do enact as follows:</ns0:Preamble>
                <ns0:BillSection id="id_D7283FDA-DB95-402F-9761-E7BAE1C8D90A">
                        <ns0:Num>SECTION 1.</ns0:Num>
                        <ns0:Content>
                                <html:p>
                                        (a)
                                        <html:span class="EnSpace"/>
                                        The Legislature finds and declares all of the following:
                                </html:p>
                                <html:p>
                                        (1)
                                        <html:span class="EnSpace"/>
                                        California has adopted statewide climate and air quality goals that require substantial reductions of the emissions of greenhouse gases from buildings and industrial sectors, including emissions associated with heating and cooling.
                                </html:p>
                                <html:p>
                                        (2)
                                        <html:span class="EnSpace"/>
                                        Thermal energy networks and other nonemitting shared thermal infrastructure systems can provide heating and cooling services without onsite combustion of fossil fuels or water-intensive traditional evaporative cooling, while maintaining reliability and enabling a range of clean thermal energy sources, including geothermal and industrial waste heat.
                                </html:p>
                                <html:p>
                                        (3)
                                        <html:span class="EnSpace"/>
                                        Existing law authorizes investor-owned utilities to provide electricity or natural gas service, but does not expressly authorize those utilities to provide heating or cooling as a regulated utility service through thermal energy networks or similar infrastructure at a commercial or industrial scale.
                                </html:p>
                                <html:p>
                                        (4)
                                        <html:span class="EnSpace"/>
                                        The absence of clear statutory authority for gas corporations to provide thermal energy service creates legal and regulatory uncertainty that limits the development of thermal energy networks and inhibits investment in zero-emission infrastructure.
                                </html:p>
                                <html:p>
                                        (5)
                                        <html:span class="EnSpace"/>
                                        The Legislature has previously authorized new utility functions in response to evolving technologies and public policy needs, subject to regulation by the Public Utilities Commission.
                                </html:p>
                                <html:p>
                                        (b)
                                        <html:span class="EnSpace"/>
                                        It is the intent
                  of the Legislature in enacting this act to remove legal barriers to the provision of thermal energy service by gas corporations, while preserving the Public Utilities Commission’s authority to regulate that service in the public interest.
                                </html:p>
                                <html:p>
                                        (c)
                                        <html:span class="EnSpace"/>
                                        This act does not mandate the deployment of any specific technology, require a gas corporation to undertake a particular project, or alter existing obligations to provide natural gas service, except as determined by the Public Utilities Commission pursuant to its authority.

                                                                “Thermal energy network” means a multiuser system of piped noncombustible fluids that are used for transferring thermal energy into and out of buildings or industrial processes for the purpose of providing zero-emission heating, cooling, or process heat.
