CALIFORNIA LEGISLATURE— 2017–2018 REGULAR SESSION

Senate Bill No. 1339


Introduced by Senator Stern

February 16, 2018


An act to add Chapter 4.5 (commencing with Section 8370) to Division 4.1 of the Public Utilities Code, relating to electricity.


LEGISLATIVE COUNSEL'S DIGEST


SB 1339, as amended, Stern. Electricity: microgrids: tariffs.
(1) Under existing law, the Public Utilities Commission (PUC) has regulatory authority over public utilities, including electrical corporations, while local publicly owned electric utilities, as defined, are under the direction of their governing boards. Existing law authorizes the commission to fix the rates and charges for every public utility and requires that those rates and charges be just and reasonable.
This bill would require the commission, as part of a specified rulemaking, to consider the role of microgrids in providing grid resiliency and to establish a tariff for each electrical corporation for the use of microgrids to provide electrical grid resiliency. The bill would require the commission (1) to direct each electrical corporation to file an advice letter implementing the tariff, (2) to approve an advice letter only if it minimizes costs and maximizes benefits to all ratepayers and meets the requirements of the rulemaking, and (3) to approve, reject, or modify each advice letter before January 1, 2020. PUC, in consultation with the State Energy Resources Conservation and Development Commission and the Independent System Operator, to take specified actions by January 1, 2020, to facilitate the commercialization of microgrids for distribution customers of electrical corporations. The bill would prohibit the PUC from permitting a microgrid that uses diesel backup or gas-combustion generation. The bill would require a local publicly owned electric utility that serves more than 700,000 customers to develop a process for interconnection of customer-supported microgrids and to make this process available by January 1, 2020. The bill would prohibit these local publicly owned electric utilities from permitting a microgrid that uses diesel backup or gas-combustion generation.

This bill would require each local publicly owned electric utility to establish a tariff, to be available for service before January 1, 2020, for the use of microgrids to provide electrical grid resiliency.

This bill would require each state agency to consider integrating microgrids into its infrastructure.

Under existing law, a violation of any order, decision, rule, direction, demand, or requirement of the commission is a crime.
Because the provisions of this bill would require an order or other action of the commission to implement, and a violation of that order or action would be a crime, the bill would impose a state-mandated local program.
In addition, by placing requirements upon local publicly owned electric utilities, the bill would impose a state-mandated local program.
(2) 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.
This bill would provide that no reimbursement is required by this act for specified reasons.
Vote: MAJORITY   Appropriation: NO   Fiscal Committee: YES   Local Program: YES  

The people of the State of California do enact as follows:


SECTION 1.

The Legislature finds and declares all of the following:

(a)Climate change impacts California’s economy and residents in many ways, including by threatening critical infrastructure, increasing the frequency and severity of climate-related natural disasters, and interrupting critical services, such as the delivery of water, goods, and electricity.

(b)Critical infrastructure, including, but not limited to, hospitals, health centers, data centers, and telecommunications, energy, financial service, water, and transportation infrastructure, comprises physical and virtual systems and assets so vital to California, especially in situations requiring a rapid emergency response or asset deployment, that the incapacity or destruction of them would have a debilitating impact on national and local security, public health and safety, and economic security.

(c)The Office of Emergency Services’ “State of California Threat and Hazard Identification and Risk Assessment” outlined capability targets for infrastructure systems, including to stabilize critical infrastructure functions, such as energy, transportation, telecommunications, water and wastewater services, and public health and medical systems, within the first 72 hours after an incident.

(d)A resilient energy system that is built with the capacity to withstand and rapidly recover from a service disruption, including, but not limited to, a deliberate attack, or an accident, fire, flood, mudslide, or other natural disaster, is necessary to preserve the economic vitality, public health and safety, and well-being of California’s citizenry in the face of natural threats to, or other interruptions of, California’s electrical supply.

(e)Microgrids, and other distributed energy resources and transmission improvements, can make the electrical grid more resilient during and after disruptive events, as a potential source of backup generation and durable supply, to support and aid in the recovery of critical infrastructure functions in emergencies or during disruptions to the electrical supply. Generally, microgrids can enhance system reliability, provide economic benefits, and help the state meet its clean energy and greenhouse gas emissions reduction goals.

(f)Microgrids can also reduce California’s reliance on diesel-fired backup generation resources and thereby help to achieve the state’s aggressive air quality goals, which were furthered by the enactment of Chapters 135 and 136 of the Statutes of 2017, and to ensure all communities achieve high air quality levels. The effects noted in subdivision (e) and this subdivision motivate the adoption of technology solutions with minimal negative impacts to local air pollution, like microgrids.

(g)Each utility should work to incorporate an electrical grid resiliency plan into its overall distribution grid planning process. The plan should identify the investments necessary to increase the resiliency of the electrical grid and reduce the risk of electrical outages affecting emergency services, critical circuits, and critical infrastructure, and should explain how the plan’s execution would increase grid resiliency in a manner that both maximizes the benefits and minimizes the costs to ratepayers.

(h)Additionally, the appropriate state energy agencies, including the Public Utilities Commission and the State Energy Resources Conservation and Development Commission, should, based on the best available data, in consultation with other agencies or entities as appropriate, including, but not limited to, the Office of Emergency Services, the Independent System Operator, and the United States Department of Homeland Security, review the electrical grid resiliency plans and associated investment strategies.

(i)California could benefit from the implementation of microgrids at state-owned facilities and other critical infrastructure sites.

SECTION 1.

 The Legislature finds and declares all of the following:
(a) Many electricity customers are seeing the potential benefits of investing in their own distributed energy resources as part of microgrids, both to ensure their own level of reliability and to better manage their own usage.
(b) Allowing the electricity customer to manage itself according to its needs, and then to act as an aggregated single entity to the distribution system operator, allows for a number of innovations and custom operations.
(c) Key issues facing commercializing microgrids that must be addressed include all the following:
(1) How microgrids operate and their value.
(2) Improving the electrical grid with microgrids.
(3) How microgrids can play a role in implementing policy goals.
(4) How microgrids can support California’s policies to integrate a high concentration of distributed energy resources on the electrical grid.
(5) How microgrids operate in the current California regulatory framework.
(6) Microgrid technical challenges.
(d) The Public Utilities Commission, Independent System Operator, and State Energy Resources Conservation and Development Commission must take action to help transition the microgrid from its current status as a promising emerging technology solution to a successful commercial product that helps California meet its future energy goals and provides end-use electricity customers new ways to manage their individual energy needs.
