Electrifying California’s Water Districts: Networked EV Charging Built for Public Fleet Readiness – EV Charging Case Study
How TurnOnGreen and Epic Charging help California water districts meet CARB requirements, unlock grant funding, and run electric fleets with full visibility, control, and long-term cost efficiency.
Introduction
California’s public fleet transition is no longer a future planning exercise. It is happening now, and water districts are among the agencies feeling the pressure first. Medium and heavy-duty vehicles must begin shifting to zero-emission alternatives, budgets must absorb new infrastructure investments, and day-to-day operations must continue without disruption.
Delivering on all three requires more than chargers on the ground. It requires a networked charging platform built for the realities of public sector fleets: regulated, grant-funded, and operationally accountable. That is where the partnership between TurnOnGreen and Epic Charging comes in.
Together, TurnOnGreen’s commercial charging hardware and dedicated client support team, in conjunction with Epic Charging’s U.S.-based network platform give California water districts the tools to electrify confidently, report credibly, and plan for the next decade of fleet operations.

Background
Water districts across California vary widely in size, service area, and fleet profile. The California Water Districts landscape generally falls into three tiers:
For water districts, this is not only a compliance question. It is a long-horizon operational and financial decision: where to put chargers, how to fund them, how to run them efficiently, and how to prove the investment delivered value.
- Tier 1 agencies operating 300 to 1,000 vehicles
- Tier 2 agencies operating 75 to 300 vehicles
- Tier 3 agencies operating 20 to 75 vehicles
For water districts, this is not only a compliance question. It is a long-horizon operational and financial decision: where to put chargers, how to fund them, how to run them efficiently, and how to prove the investment delivered value.
Challenges
Water districts approaching fleet electrification typically run into four interconnected challenges.
Regulatory transition.
CARB’s Advanced Clean Fleets rule sets firm milestones for ZEV purchases. Agencies that delay charging infrastructure planning risk arriving at a procurement year with vehicles on order and nowhere reliable to charge them.
Infrastructure cost.
Building charging at corporation yards, pump stations, or satellite facilities carries real capital cost. Many Tier 2 and Tier 3 districts cannot absorb that spend without stacking grants from sources such as the California Energy Commission, EnergIIZE, local utility incentive programs, and Air Quality Management District funding. Grant eligibility, however, increasingly depends on networked, reportable charging rather than stand-alone stations.
Operational visibility.
Fleet managers need to see what their chargers are doing in real time: which vehicles are charged, how many kWh they consumed, which sessions were authorized, how public chargers are utilized and whether any sites are underperforming. Without that visibility, districts cannot defend budgets, verify grant compliance, or plan expansion.
Future-proofing.
As fleets grow, charging load grows with them. Districts need a platform that can accommodate power management, demand response, and public charging compliance obligations as deployments scale. Most importantly, they rely on the client service team at TurnOnGreen and Epic charging to plan expansion, while providing operations and maintenance support on an annual basis.

Solution
The TurnOnGreen and Epic Charging partnership addresses these challenges as a single, integrated system. TurnOnGreen provides commercial charging hardware engineered for fleet and public agency use coupled with accessible and responsive client services for operations and maintenance. Epic Charging provides the CTEP approved software and network that turn those chargers into managed, reportable, monetizable assets.
Through the TurnOnGreen EPIC Charging platform, California water districts gain:
Through the TurnOnGreen EPIC Charging platform, California water districts gain:
- Accurate kWh tracking across every session and every site, supporting both internal cost accounting and external grant reporting
- ISO 15118 compatibility for auto-start by vehicle, reducing friction for fleet drivers
- CTEP compliance for sites that need to support public charging alongside fleet use
- Power management and load balancing to control demand charges and future-proof electrical capacity as the fleet grows
- Detailed reporting aligned with California grant program requirements
- Demand response participation and LCFS credit monetization to turn charging activity into a revenue stream rather than a sunk cost
Impact
For water districts moving through the early years of fleet electrification, the combined TurnOnGreen and Epic Charging approach delivers value on several fronts at once.
It supports grant readiness by producing the networked, reportable data that modern California grant programs expect. It enables lower total cost of ownership by giving districts the visibility to manage energy costs actively rather than absorbing whatever the utility bill shows at the end of the month. It preserves operational continuity through reliable, vehicle-aware charging that keeps crews moving. And it future-proofs the site for the load growth that will follow as more ZEVs enter the fleet.
Critically, the platform converts charging from a pure cost center into a strategic asset. LCFS monetization and demand response can offset infrastructure and energy spend, helping smaller Tier 2 and Tier 3 districts stretch constrained budgets further.

Key Highlights
- Built for public sector fleet electrification, with reporting aligned to California grant and compliance requirements
- Networked charging that meets the criteria for California Energy Commission, EnergIIZE, utility, and AQMD funding programs
- ISO 15118 vehicle auto-start, kWh-level tracking, and CTEP public charging compliance
- Power management and demand response to control energy costs as fleets scale
- LCFS credit monetization to turn charging activity into recurring revenue
- TurnOnGreen hardware and Epic Charging software delivered as a single integrated solution, backed by CA based technical support teams
Conclusion
California water districts are not choosing whether to electrify. The regulatory and economic signals have already made that decision. What they are choosing is how to electrify: with charging infrastructure that is operationally visible, financially accountable, and ready to scale, or with disconnected hardware that leaves value on the table.
TurnOnGreen and Epic Charging offer a path that respects the realities of public agency budgets and the requirements of California’s grant and compliance environment. It is a networked, software-first approach to fleet charging, designed for agencies that need to move quickly without compromising on control.
For water districts preparing for the next wave of ZEV purchases, the question is no longer whether networked charging matters. It is how soon it can be in the ground.
