California commercial energy strategy operates inside the most regulated electricity market in the country, with PG&E, SCE, SDG&E, SoCalGas, LADWP, and SMUD each carrying distinct tariff structures, demand response programs, and incentive frameworks. Commercial demand charges in California are routinely the highest in the country; tariff schedule election (B-19 versus E-19 versus A-10 on PG&E, TOU-GS-1 through TOU-8 on SCE) drives 15 to 30 percent variance on the same load. The April 2023 NEM 3.0 transition reset solar economics, making behind-the-meter storage the central engagement lever rather than export-driven solar. Self-Generation Incentive Program (SGIP) rebates, Capacity Bidding Program demand response, and Demand Response Auction Mechanism participation stack with the storage. Developments CS works across all four IOUs plus LADWP and SMUD, with attention to schedule election, NEM 3.0 sizing, and the SGIP rebate filing windows.

Major utilities we work with

Utilities we track in California

Each utility carries its own tariff book, demand structure, and program environment. The engagement maps every account against every applicable schedule.

  • Pacific Gas and Electric (PG&E)

    combined

    Electric and gas service across Northern and Central California. Commercial demand charges among the highest in the country; tariff schedule choice (A-6, A-10, B-19, B-20, E-19, E-20) can drive 15 to 30 percent variance on the same load.

  • Southern California Edison (SCE)

    electric

    Electric distribution across most of Southern California excluding LA Department of Water and Power territory and San Diego County. Commercial tariffs run from TOU-GS-1 through TOU-8 with materially different demand and energy structures.

  • San Diego Gas and Electric (SDG&E)

    combined

    Electric and gas service in San Diego and southern Orange counties. Commercial rates run higher than PG&E and SCE on most schedules; demand response programs are also more lucrative.

  • Los Angeles Department of Water and Power (LADWP)

    combined

    Municipal utility serving the City of Los Angeles. Operates on its own rate structure outside CPUC jurisdiction; separate incentive programs run independent of statewide initiatives.

  • SoCalGas

    gas

    Natural gas distribution across Central and Southern California, including most of LA Basin. Commercial gas tariffs (GN-10, GN-50, GT-F) carry distinct customer-charge and volumetric structures.

  • Sacramento Municipal Utility District (SMUD)

    electric

    Municipal electric utility serving the Sacramento area. Separate rate structure and incentive programs from the IOUs.

Programs we capture

Key California programs the engagement stacks into

State and utility programs that stack with the underlying tariff and procurement work to compound the annualized recovery.

  • Rebate

    Self-Generation Incentive Program (SGIP)

    CPUC-administered rebate for behind-the-meter storage and clean generation. Commercial battery storage projects in PG&E, SCE, SDG&E, and SoCalGas territory earn $150 to $1,000 per kWh of installed capacity depending on category and equity status.

  • Tariff structure

    California Solar Initiative successor / NEM 3.0 net billing tariff

    Successor to net energy metering. Commercial solar exports earn export compensation values that vary by hour. Engagement economics changed materially in April 2023; project sizing and storage pairing now drives most of the payback.

  • Demand response

    Demand Response Auction Mechanism (DRAM)

    Auction-based demand response program where aggregators bid load reductions into the CAISO wholesale market. Commercial sites with at least 50 kW of dispatchable load qualify through an aggregator relationship.

  • Tax credit

    California Energy Commission Tax Exclusion for advanced manufacturing

    Sales and use tax exclusion on equipment purchases for projects that promote energy efficiency or alternative energy. Commercial manufacturing and clean tech project equipment purchases qualify on application.

  • Rebate

    California Climate Investments Industrial Sector grants

    Cap-and-trade-funded grant programs for industrial energy efficiency and emissions reduction. Eligibility varies by industry classification and project type.

  • Demand response

    Capacity Bidding Program (CBP)

    PG&E, SCE, and SDG&E demand response program with monthly capacity payments for committed load reduction during dispatched events. Pairs cleanly with on-site storage.

What an engagement looks like

How a California engagement runs

A California engagement starts with a tariff schedule review. The PG&E, SCE, and SDG&E commercial tariff books include 8 to 12 schedules each that a given commercial load could potentially elect, and the schedule that was on the account at original service installation is rarely the schedule that fits the load five or ten years later. The first deliverable is a twelve-month interval-data analysis run against every eligible schedule to identify the optimal classification.

From there, the engagement layers in demand response enrollment (Capacity Bidding Program on PG&E and SCE, DRAM through an aggregator across all three IOUs), Self-Generation Incentive Program (SGIP) rebate filings for any existing or planned behind-the-meter storage, and a structural review of post-NEM-3.0 solar economics. NEM 3.0 changed the math on California commercial solar materially; sizing storage to match the export compensation curve is now where most of the payback lives.

For manufacturing operators, the California Energy Commission sales and use tax exclusion on qualifying equipment purchases is a separate recovery track. For multifamily and commercial real estate portfolios, the SGIP equity resilience tier produces materially higher rebate values where the property qualifies. The engagement runs across PG&E, SCE, SDG&E, SoCalGas, LADWP, and SMUD territory; the tariff and program detail is utility-specific, but the methodology travels.

Sample finding patterns

What the pipeline catches in California

Plausible examples drawn from the pattern types most commonly caught in California. Specific clients are not named; utilities, tariff codes, and recovery ranges are. Recovery ranges are stated as ranges (typically the 25th to 75th percentile of the relevant cohort), never as point estimates.

  • Tariff schedule election

    PG&E · B-19 vs E-19 vs A-10

    A Bay Area office and lab campus operating on PG&E B-19 (medium general demand-metered) was carrying a load profile that fit cleanly on E-19 (medium general TOU-demand). Modeling twelve months of interval data on both schedules showed a structural 12 percent annual savings on E-19 with no operational change. Election filed; bill impact landed on the next cycle.

  • Demand response stacking

    SCE

    A Southern California cold storage operator had on-site battery storage installed for solar self-consumption but never enrolled in any demand response program. Adding Capacity Bidding Program enrollment alongside the existing storage produced monthly capacity payments without changing operational behavior. Dispatch events average four to six per year; payments cover the storage finance cost on most facilities.

  • SGIP storage rebate eligibility recovery

    PG&E

    A multifamily portfolio in PG&E territory had completed battery storage installations at six properties without filing for SGIP. The program permits late application within a defined window. Filings went in across all six properties; the rebate covered roughly 35 percent of the installed cost on each project.

  • Gas tariff schedule election

    SoCalGas · GN-10 vs GN-50

    A Los Angeles industrial laundry was billed on a GN-10 small commercial tariff but consuming volumes that put the load squarely on GN-50 medium commercial terms. The customer charge differential and volumetric rate spread produced a structural 14 percent annual savings on the correct schedule. The election required a CPUC-compliant filing and a load study.

Where to next

The disciplines that drive the work in California

The California engagement runs across all our standard service lines. Tariff and rate audits and billing forensics produce the immediate-cycle bill corrections; demand management and supply procurement cut the structural cost base; incentives and grants stack utility and state program funding into capital projects; tax and fee recovery surfaces back-credit on prior overpayments where qualifying use applies.
