Market Overview
CoServ is a member-owned, vertically integrated cooperative and a Non-Opt-In Entity (NOIE) in North Texas. It opted out of the deregulated ERCOT retail market, so customers cannot shop for a competitive retail electric provider. Rates are set by the member-elected Board of Directors with minimal external rate regulation, and CoServ does not participate in Smart Meter Texas.

Current Rate Schedules
CoServ's non-residential rates are split at a 35 kW demand threshold: the Commercial rate for accounts under 35 kW and the Industrial rate for accounts of 35 kW or more, plus Public Building and Time-of-Use options. The figures below are verified from CoServ's published commercial rate page effective May 2026. All-in energy charges combine a base rate plus the monthly Power Cost Recovery Factor (PCRF) and System Cost Recovery Factor (SCRF); the all-in values shown reflect the May 2026 PCRF/SCRF.

Rate Recommendations by Use Case
Small commercial facility (under 35 kW)
Small retail, office and service businesses below 35 kW of demand use the Commercial rate with no demand charge.
The Commercial rate is a simple flat $0.132024/kWh (May 2026) with a $30 monthly charge and no demand charge, which is predictable for smaller loads.
- Track maximum demand in SmartHub to confirm you stay under 35 kW
- Watch the monthly PCRF/SCRF impact on the all-in rate
- If demand approaches 35 kW, model the Industrial rate before crossing the threshold
Industrial / large commercial (35 kW and above)
Manufacturing, large commercial and municipal loads at or above 35 kW use the Industrial rate, where demand charges dominate.
Energy drops to ~$0.078/kWh, but seasonal demand charges ($13.04 summer / $10.04 winter per kW) make peak demand management the key lever; Industrial TOU can lower NCP exposure to $2.35/kW.
- Request 15-minute interval data to map demand peaks
- Compare Industrial vs Industrial TOU based on your load shape
- Shift load out of the 3-8 p.m. on-peak window where possible
Public / institutional building
Schools, churches and community halls have dedicated Public Building rates with tiered energy pricing.
Public Building rates use a tiered energy structure (first 150 kWh/kW at a higher rate, excess lower) and lower customer charges, which suits institutional load patterns.
- Confirm eligibility (not for municipal facilities)
- Use the under-35 kW version if demand is small
- Review tiered energy breakpoints against your usage per kW
Historical Rate Trends
CoServ sets rates through its member-elected board and publishes annual rate-change notices. The cooperative has described recent changes as broadly revenue-neutral by rate class, with high energy users seeing small decreases and low users small increases. Month-to-month bill variation comes mainly from the PCRF and SCRF adjustments rather than base-rate changes.
January 1, 2025
2025 rate change described by CoServ as revenue-neutral by rate class; high energy users saw a small decrease and low users a small increase depending on usage.
~0% (revenue-neutral)Overall trend: Base rates relatively stable; monthly variation driven by PCRF/SCRF recovery factors.
Next expected change: Annual rate-change notice published by CoServ; PCRF/SCRF adjust monthly.
Cost Optimization Strategies
For CoServ C&I members, the dominant cost levers are the 35 kW demand threshold and, above it, seasonal demand charges. Managing peak demand and considering time-of-use options around the 3-8 p.m. on-peak window are the main savings strategies.
Manage the 35 kW threshold
For: Commercial/industrial accounts near 35 kW
Accounts near 35 kW should evaluate whether keeping maximum demand below 35 kW (Commercial rate, no demand charge) or accepting the Industrial rate with lower energy charges is cheaper for their load factor.
Peak demand management
For: Industrial-rate accounts (>=35 kW)
Use SmartHub Usage Explorer or requested 15-minute interval data to identify and reduce peak kW that drives $10.04-$13.04/kW demand charges.
Time-of-use load shifting
For: TOU Demand Metered and Industrial TOU accounts
Shift discretionary load out of the 3-8 p.m. on-peak window (and the winter 6-8 a.m. window) under a TOU schedule to reduce on-peak demand and NCP charges.

Frequently Asked Questions
Can my business get 15-minute interval data from CoServ?▾
Yes, but not as a self-service download. AMI meters capture 15-minute data that you can view in the SmartHub Usage Explorer. For a machine-readable CSV export, submit a formal data request to contact@coserv.com; CoServ typically delivers the file within 3-5 business days. Third parties must provide a Letter of Authorization.
Does CoServ support Green Button or a public API?▾
No. CoServ has not implemented Green Button (DMD or CMD) or a public developer API. The NISC SmartHub platform underneath has API capabilities, but they are not publicly available for CoServ and would require a custom agreement. The main programmatic path is a formal data request or a partnership.
Which rate applies to my commercial or industrial facility?▾
CoServ uses a demand threshold of 35 kW. The Commercial rate applies to accounts under 35 kW of maximum demand; the Industrial rate applies to accounts of 35 kW or more. There are also Public Building rates and several Time-of-Use options (Demand Metered, Industrial TOU, and Public Buildings TOU).
How do third parties get authorized to access an account?▾
CoServ uses a Letter of Authorization (LOA) process rather than a Share My Data portal. The account holder completes an LOA on company letterhead with Sales Tax ID/EIN and an authorized signature, then emails it to contact@coserv.com. Processing takes 3-5 business days.
Can I choose a different retail electricity provider?▾
No. CoServ is a Non-Opt-In Entity (NOIE) that opted out of ERCOT retail competition, so there is no retail electric provider (REP) choice in its territory. CoServ is the exclusive provider and sets its own rates through its member-elected board.
