AB 1347 directs the Governor’s Office of Business and Economic Development (GO‑Biz), working with the Independent System Operator (ISO), to identify six "electrical infrastructure modernization zones" using criteria such as economic need, lack of electrical infrastructure, projected load growth, and minimizing ratepayer impact. The bill requires the Public Utilities Commission (PUC) and the State Energy Resources Conservation and Development Commission (Energy Commission) to recognize those zones as load growth priority areas.
For customers inside a designated zone, the bill allows utilities to coordinate with local jurisdictions to update load projections, authorizes the PUC to permit expedited cost recovery under Section 937(a), and gives utilities the ability to manage microgrids (with local approval), including collecting fixed charges for non‑interconnected microgrids. The bill also mandates inclusion of the high desert area and Altadena (unincorporated Los Angeles County) among the six zones and contains a special‑statute declaration for Altadena.
At a Glance
What It Does
The bill tasks GO‑Biz and the ISO with identifying six modernization zones using specific indicators, directs the PUC and Energy Commission to treat those zones as load growth priorities, and authorizes utilities to update load forecasts, seek expedited cost recovery, and manage microgrids in those zones.
Who It Affects
Local jurisdictions in high‑growth or under‑served areas, electrical corporations serving customers in those zones, developers seeking new service, microgrid providers, and state energy regulators (PUC, Energy Commission, ISO, GO‑Biz).
Why It Matters
It creates a regulatory pathway to accelerate electric infrastructure and microgrid deployment in targeted growth areas, changes who can operate and bill for microgrids, and adjusts cost‑recovery procedures — all of which have operational, competitive, and ratepayer implications.

What This Bill Actually Does
The bill establishes a focused program to identify up to six geographic areas where electrical infrastructure upgrades and alternative approaches to serving load should be prioritized. GO‑Biz, together with the ISO, must select the areas using at least four indicators: local economic development need, lack of electrical infrastructure and delays to electrification, projected local load growth, and minimizing impacts on ratepayers.
The statute requires that two specific zones be included among the six: the "high desert" area as defined by GO‑Biz/ISO, and the unincorporated Altadena area in Los Angeles County.
Once zones are designated, the PUC and the Energy Commission must formally recognize them as load growth priority areas. That recognition unlocks three operational changes inside the zones: utilities may work with local governments to reconfigure or update their load projections; the PUC may authorize expedited cost recovery under the existing Section 937(a) process; and utilities may be authorized to manage microgrids — subject to local jurisdiction approval.
The bill anticipates two microgrid operating models: utility‑managed microgrids and customer‑contracted microgrids. If a microgrid is not interconnected to the broader electrical grid, the utility may collect a fixed charge from the microgrid’s customers.
If the utility cannot or will not manage the microgrid, individual customers may enter contracts with third‑party microgrid providers for up to 10 years, with one option to renew for an additional 10 years.The bill also includes legislative findings about statewide load growth, revenue losses to local governments from electrification delays, and the need for alternative delivery models in hard‑to‑reach areas. It contains a clause asserting a special statute for Altadena and a provision that no state reimbursement is required to local agencies under the California Constitution, on the ground that any local costs would result from the act creating or changing a crime or infraction as related to PUC enforcement.
The Five Things You Need to Know
GO‑Biz, in conjunction with the ISO, must identify six "electrical infrastructure modernization zones" using four mandatory indicators: economic development need, electrical infrastructure gaps/delays, projected local load growth, and minimizing ratepayer impact.
Two zones are expressly required: (1) the high desert area as defined by GO‑Biz/ISO, and (2) the unincorporated Altadena area in Los Angeles County—Altadena also receives a special‑statute declaration.
For designated zones the PUC and Energy Commission must recognize them as load growth priority areas, enabling altered regulatory treatment for projects and interconnection planning.
The PUC may authorize expedited cost recovery pursuant to subdivision (a) of Section 937, and may allow utilities to 'manage' microgrids with local approval; if a microgrid is not grid‑interconnected, utilities may collect a fixed charge from its customers.
If a utility does not manage a microgrid, customers may contract with a microgrid provider for up to 10 years, with a one‑time 10‑year renewal option (effectively up to 20 years total under a specific renewal framework).
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Legislative findings on load growth and infrastructure gaps
This section lists the Legislature’s factual findings: accelerating load growth, affordability pressures, and local revenue losses from delays in electrification. The findings frame the bill’s purpose — to justify a targeted, statutory approach to prioritize infrastructure where conventional planning is not keeping pace.
Designation process and required zones
Subdivision (a)(1) requires GO‑Biz and the ISO to identify six zones using four minimum indicators. Subdivision (a)(2) mandates that the high desert and unincorporated Altadena be included among the six. Practically, GO‑Biz/ISO write the geographic definitions and apply the criteria; that initial designation determines where the special rules in (b) apply.
Regulatory recognition as load growth priority areas
This clause obligates the PUC and Energy Commission to treat designated zones as load growth priorities. That recognition changes planning signals and prioritization for interconnection, distribution upgrades, and potentially funding or procedural timelines at the commission level.
Load projections, expedited cost recovery, and microgrid management
Subdivision (b)(2) allows utilities to coordinate with local jurisdictions to update electrical load forecasts — a practical step to align utility investment with local development. Subdivision (b)(3) has three effects: it authorizes PUC approval for expedited cost recovery under Section 937(a); it permits utilities to manage microgrids with local jurisdiction approval and to assess a fixed charge to customers when a microgrid is not grid‑interconnected; and it establishes that customers may contract with third‑party microgrid providers for up to 10 years with one 10‑year renewal if the utility does not manage the microgrid.
No reimbursement clause and special statute for Altadena; legislative intent
Section 3 asserts no state reimbursement to local agencies under Article XIII B, basing that assertion on the claim that any local costs arise from changes to crimes or infractions tied to PUC actions. Section 4 declares Altadena requires a special statute. The final intent paragraph signals that the Legislature expects follow‑on legislation to implement a broader electric modernization zone program in partnership with the PUC, Energy Commission, Department of Fish and Wildlife, GO‑Biz, and ISO.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Rapidly growing local jurisdictions (e.g., designated high desert communities and Altadena): Recognition as load growth priorities speeds planning and can reduce time-to-service for developers and businesses seeking new connections.
- Developers and commercial projects in designated zones: Faster load forecasting and prioritized infrastructure work can shorten project timelines and lower soft costs tied to electrical delays.
- Electrical corporations (utilities): The bill grants tools — coordinated load updates, PUC‑authorized expedited cost recovery, and authority to manage microgrids — that can stabilize revenue recovery and expand operational roles.
Who Bears the Cost
- Ratepayers in and potentially outside designated zones: Expedited cost recovery under Section 937(a) could accelerate the pace at which utility investments are passed through to customers, and fixed charges for off‑grid microgrid customers could shift billing burden.
- Local jurisdictions: They must engage in load‑forecast updates and local approval processes, absorbing staff time and coordination costs even though the bill asserts no state reimbursement.
- Third‑party microgrid providers: Authorizing utility management of microgrids can reduce market opportunities; providers face contract length constraints (10 years plus one renewal) that affect financing and business models.
Key Issues
The Core Tension
The central dilemma is between speed and control: the bill prioritizes rapid electrification and infrastructure deployment in targeted zones (favoring developers and planning timelines) while expanding utility authority and expedited cost recovery (risking higher or faster cost recovery from ratepayers and constraining third‑party competition). Reasonable stakeholders will disagree over whether the benefits of accelerated service outweigh the regulatory, competitive, and distributional trade‑offs.
The bill pulls several levers at once — geographic prioritization, altered planning, expedited cost recovery, and utility authority over microgrids — but it leaves significant implementation detail unresolved. It does not set a transparent scoring or weighting mechanism for the four designation indicators, which makes the selection process administratively discretionary and potentially contentious.
The mechanics of how the PUC will implement 'expedited cost recovery' under Section 937(a) in practice are unspecified: the bill does not define timelines, cost‑allocation principles, or how to reconcile minimizing ratepayer impact with faster recovery of utility investments. That tension creates real regulatory work for the PUC and contested issues in rate cases.
Allowing utilities to manage microgrids and to levy fixed charges when microgrids are not interconnected raises competition and tariff design questions that the bill does not address. The law creates a choice architecture that could favor incumbent utilities over third‑party microgrid developers; it also leaves open how fixed charges are calculated and whether they will be reviewed for fairness by the PUC.
The customer contract term (10 years with a one‑time 10‑year renewal) constrains procurement structures and could limit financing options for new entrants. Finally, the bill’s special‑statute carveout for Altadena and the 'no reimbursement' assertion rest on legal rationales that may invite scrutiny, since the practical costs of coordination and enforcement still fall on local governments and agencies.
