Turlock Irrigation District (TID) Rate Selection Guide
Turlock Irrigation District (TID) is California's oldest publicly owned irrigation district (founded 1887), providing electric service to roughly 95,700 customers plus irrigation water across Stanislaus and Merced counties. As a public, not-for-profit district, TID sets its own rates and offers billing and usage data through the My TID (Oracle Opower) portal, with 15-minute interval data available to large industrial customers via Meter Manager.

Market Overview
As a California public irrigation district, TID self-regulates its electric rates through its elected Board of Directors rather than the CPUC. Customers cannot choose a competitive energy supplier; all electric service is provided by TID under published tariff schedules.

Current Rate Schedules
TID's current electric tariffs took effect January 1, 2025, following a multi-year rate plan adopted at the November 26, 2024 public hearing (with further increases scheduled for 2026 and 2027). C&I schedules range from CE/CT (under 35 kW) through ID/IT, HT, XT, and BP for the largest industrial loads. Larger schedules are time-of-use with separate summer/winter demand and energy charges plus a power factor charge. Verified figures below are drawn from TID's published Schedule HT tariff; CE/CT/ID/IT/XT/BP rates are structurally similar — see the linked tariff PDFs for exact figures.

Rate Recommendations by Use Case
Large industrial facility (500+ kW)
Facilities on HT/XT/BP should manage peak demand and shift load off the noon-9pm on-peak window to control summer demand and energy costs.
Summer demand charges reach $15.00/kW and summer on-peak energy is $0.1425/kWh on HT, so trimming coincident peak and shifting production off-peak yields the largest savings. Power factor correction below the 62% kVAr threshold avoids the $1.10/kVAr charge.
- Enroll in Meter Manager to see 15-minute load profiles and demand alerts
- Shift discretionary load out of the 12pm-9pm on-peak window
- Correct power factor to stay under 62% of kW demand
- Evaluate interruptible/non-firm credits if load is curtailable
- Pursue 12kV or 69kV+ service for 2.5%-6% energy discounts where feasible
Mid-size commercial / small industrial (35-499 kW)
Customers in the 35-499 kW range on ID/IT should compare standard demand pricing against time-of-use and focus on demand management.
At this size a demand charge applies, so reducing peak kW and (on IT) shifting use off-peak both lower bills. The right choice depends on how concentrated the facility's load is during peak hours.
- Pull 12 months of usage from My TID to model demand vs. TOU
- Stagger equipment startups to limit coincident peak
- Consider IT if load can be shifted off-peak
- Request a Public Records data pull for granular interval history if needed
Small business under 35 kW
Small commercial accounts on CE or CT should use My TID to track usage and decide whether time-of-use (CT) saves money versus standard service.
Under-35-kW accounts have no demand charge, so the main lever is energy use and, on CT, when that energy is consumed. Businesses that can shift load off-peak may benefit from CT.
- Use My TID usage charts and cost projections
- Compare CE vs. CT using your hourly usage pattern
- Export Green Button data for deeper analysis

Historical Rate Trends
TID adopted a multi-year rate plan at its November 26, 2024 public hearing, with increases effective January 1 of 2025, 2026, and 2027. Schedule HT illustrates the trajectory: the customer charge rises from $275 (2025) to $300 (2026) to $350 (2027), with demand and energy charges stepping up each year.
January 1, 2025
First step of the multi-year plan: HT customer charge set at $275/mo, summer demand $15.00/kW, summer on-peak energy $0.1425/kWh.
Multi-year planJanuary 1, 2026
Second step: HT customer charge rises to $300/mo, summer demand to $16.00/kW, summer on-peak energy to $0.1464/kWh.
Scheduled stepJanuary 1, 2027
Third step: HT customer charge rises to $350/mo, summer demand to $18.00/kW, summer on-peak energy to $0.1471/kWh.
Scheduled stepOverall trend: Rising. Scheduled annual increases through 2027 reflect higher wholesale power and infrastructure costs.
Next expected change: January 1, 2027 (final step of the adopted multi-year plan)
Cost Optimization Strategies
For TID C&I accounts, the biggest savings levers are peak demand management, time-of-use load shifting, power factor correction, and (for large loads) service voltage selection. Interval visibility through Meter Manager is the foundation for all of these.
Peak demand management
For: ID, IT, HT, XT, BP
Limit coincident 15-minute peak kW by staggering equipment and capping demand, since the monthly demand charge is set by the single highest 15-minute interval.
Time-of-use load shifting
For: CT, IT, HT, XT, BP
Move discretionary production and HVAC out of the 12pm-9pm on-peak window to capture lower off-peak energy rates.
Power factor correction
For: HT, XT, BP
Install capacitors to keep reactive demand under 62% of kW demand and avoid the per-kVAr power factor charge.
Service voltage optimization
For: HT, XT, BP
Take delivery at higher voltage (12kV or 69kV+) to earn energy charge discounts where the facility can accommodate it.

Frequently Asked Questions
How does a commercial or industrial customer get 15-minute interval data from TID?▾
Large industrial customers on the HT (500-2,999 kW), XT (3,000-6,999 kW), or BP (7,000+ kW) rate schedules can enroll in Meter Manager by calling TID Customer Service at (209) 883-8506. Meter Manager provides 15-minute interval load profiles, demand alerts, and cost analytics. Smaller commercial accounts see daily/weekly/monthly usage in My TID and can request granular records via a Public Records Request.
Can a third-party energy consultant access our TID account data?▾
Yes, but only with written customer authorization under California PUC Section 8380. TID does not run an automated Share My Data portal, so the customer signs an authorization naming the third party, account numbers, data scope, and duration, then the consultant contacts (209) 883-8506 to be provisioned. Alternatively, the customer can export Green Button CSV/XML or Meter Manager reports and hand the files to the consultant.
Does TID offer an API or EDI feed for aggregators?▾
No public self-service API or EDI program for customer data is documented. The underlying Oracle Opower DSS platform has APIs in some deployments, but use requires Oracle licensing and TID IT involvement. Aggregators should contact TID at (209) 883-8506 to discuss a custom integration or pilot.
What rate schedules apply to commercial and industrial TID customers?▾
C&I customers fall on CE (commercial under 35 kW), CT (commercial TOU under 35 kW), ID/IT (small industrial 35-499 kW), HT (large industrial 500-2,999 kW, TOU), XT (very large industrial 3,000-6,999 kW, TOU), and BP (bulk power 7,000+ kW, TOU). Larger schedules are time-of-use with summer/winter demand and energy charges; the current tariffs took effect January 1, 2025.
When does TID's on-peak period occur for TOU schedules?▾
For industrial TOU schedules such as HT, the on-peak period is 12 noon to 9 p.m. Monday through Friday, with all other hours and listed holidays treated as off-peak. Summer billing months run June through November and winter months run December through May, with higher summer demand and energy rates.
