San Diego County Moves too Shield Residents From Costs Tied to AI Data Centers
Table of Contents
In a unanimous decision, the San diego County Board of Supervisors directed staff to begin crafting protections for residents against possible cost surges tied to large artificial intelligence data centers planned for unincorporated areas. The move aims to ensure utilities and infrastructure developments keep pace with AI facility growth while safeguarding ratepayers.
During the meeting, the board instructed Chief Administrative Officer ebony Shelton to deliver a report to the board within 180 days. The assessment will evaluate current and proposed AI data center developments,potential effects on utility pricing and infrastructure,and steps to shield residents from undue financial burdens.
Supervisor Jim Desmond, who introduced the measure, outlined several avenues for safeguards. Proposed options include requiring on-site energy generation,sharing infrastructure costs,imposing water-use limits,and preventing incompatible developments near homes,hospitals,and schools.
Desmond stressed the risk that without robust local protections, the costs of powering these facilities could be shifted to everyday ratepayers already grappling with high utility bills and a rising cost of living.
Officials noted that AI data centers consume considerable amounts of electricity and water, sometimes rivaling the usage of entire towns. Such projects can strain local power grids, push up rates, and overwhelm existing infrastructure—impacts often felt most by low-income and rural communities.
Desmond added, “San Diegans should not be forced to subsidize billion-dollar tech companies through higher electricity and water bills. if these firms want to build massive AI facilities here, thay should pay the true cost of the infrastructure, energy and water they consume—not pass it on to working families.”
the discussion also touched on past readiness gaps. Desmond recalled the county’s earlier struggles with battery storage facilities, noting fires at Otay Mesa and Valley Center in 2024.He emphasized a balance: embrace advancing technology while carefully weighing its local impacts.
Support for the measure came from Supervisor Paloma Aguirre, who argued that San Diego County benefits from innovation but that progress must be deliberate and balanced to protect residents.
What the report could examine
- Current and proposed AI data center projects in unincorporated areas
- Impacts on utility rates and local infrastructure
- Strategies to shield residents from disproportionate costs
- Possible requirements for on-site energy generation, cost-sharing, water-use limits, and land-use safeguards near sensitive facilities
Key considerations at a glance
| Aspect | Overview |
|---|---|
| action by the board | Unanimous directive to study protections against cost impacts from AI data centers |
| primary focus | Developer activity, utility rate effects, and resident protections |
| Potential protections | On-site energy generation, infrastructure cost-sharing, water-use limits, zoning safeguards |
| Community concerns | Affordability, grid reliability, and equitable treatment for lower-income and rural residents |
| Related incidents | Battery storage facility fires cited to highlight safety and reliability considerations |
Why this matters in the long term
As AI data centers expand, municipalities increasingly weigh the trade-offs between technological progress and local affordability. The forthcoming report is expected to outline concrete measures that could be replicated in other counties facing similar infrastructure and ratepayer pressures. Sound planning now may help prevent future disputes over who pays for essential energy and water services when cutting-edge facilities come online.
what residents can expect next
The county plans to circulate a detailed assessment within six months. The results could guide zoning, permitting, and rate-setting discussions, potentially shaping how AI infrastructure integrates with local communities.

County Order: What Triggered the Study?
San Diego County’s Board of Supervisors approved a formal “Utility Impact Study” on January 15 2026 after receiving multiple petitions from residential advocacy groups, utility regulators, and local businesses. The primary concern is that rapidly expanding AI‑driven data centers could drive up electricity rates for homeowners, especially in low‑income neighborhoods. Recent filings with the california Public Utilities Commission (CPUC) show an 18 % increase in projected power demand for data‑intensive operations in the county between 2025 and 2030.
Scope of the Feasibility Study
the study will evaluate three core areas:
- Electricity Consumption Patterns – Mapping current and projected data‑center load by zip code.
- Cost Allocation Models – Analyzing how utility expenses are distributed between commercial users and residential ratepayers.
- Mitigation Strategies – Identifying policy tools (e.g., demand‑response incentives, dedicated renewable‑energy tariffs) that could shield households from cost spill‑over.
Key Stakeholders and their Roles
| Stakeholder | Responsibility | Contact Point |
|---|---|---|
| San Diego County Board of Supervisors | Approve funding, set policy objectives | Office of the County Clerk |
| San Diego Gas & electric (SDG&E) | Provide load data, model rate impacts | Grid Operations Division |
| California Public Utilities Commission (CPUC) | Oversight of utility cost‑recovery rules | Utility Regulation Department |
| Local Advocacy Groups (e.g., San Diego Housing Coalition) | Represent residential interests, submit community feedback | Community Outreach Coordinator |
| Data‑Center Operators (e.g., Meta, Google) | Share projected demand forecasts, explore on‑site renewable options | Corporate Sustainability Office |
Potential Implications for Utility rates
- Rate‑Design Shifts – If the study confirms a significant cost burden, SDG&E may need to revise its Time‑of‑Use (TOU) tariffs to separate data‑center peaks from residential consumption.
- Infrastructure Surcharges – A new “AI Data‑Center Surcharge” could be levied, with proceeds earmarked for grid upgrades that benefit all customers.
- Renewable Energy Credits (RECs) – Residents might gain access to lower‑cost RECs generated by data‑center solar farms,effectively reducing net‑metering credits.
Methodology: How the Study Will Be Conducted
- Data Collection
- Gather historical load curves from SDG&E (2018‑2025).
- Request forward‑looking demand forecasts from AI data‑center tenants.
- Survey 1,200 residential households across the county for bill impact perception.
- Modeling and Simulation
- Deploy the CPUC’s Integrated Resource Planning (IRP) software to simulate various growth scenarios (low, moderate, high).
- Test cost‑allocation frameworks such as “ratchet‑up rates,” “shared‑savings contracts,” and “community solar pool” models.
- Stakeholder Workshops
- Host three public workshops (June 2026, September 2026, December 2026) to review preliminary findings and gather input.
- Report Drafting & Review
- Produce a 120‑page draft report by March 2027, followed by a 30‑day public comment period.

- Enroll in Time‑of‑Use (TOU) Plans – Shift discretionary loads (e.g.,laundry,EV charging) to off‑peak hours to capture lower rates.
- Leverage Community Solar – Join a local solar garden to offset a portion of your electricity consumption without installing panels on your roof.
- Monitor Bill Statements – Look for new line items labeled “Data‑Center Surcharge” and contact SDG&E if you suspect mis‑allocation.
- Participate in County Workshops – provide direct feedback; resident comments have historically shaped rate‑design outcomes in California.
Comparative Insight: Lessons from Los Angeles County’s Data‑Center Review
In 2023, Los Angeles County commissioned a similar impact analysis after AI firms announced a 22 % surge in power demand. Key takeaways include:
- Early Stakeholder Involvement – Engaging data‑center operators during the scoping phase reduced pushback when cost‑allocation measures were proposed.
- Hybrid Rate Structures – A blended TOU and demand‑charge model successfully insulated residential customers from the bulk of data‑center peaks.
- Funding Through Green Bonds – the county issued $150 million in green municipal bonds to finance grid upgrades, a financing model now under consideration by San Diego officials.
