Rules by state · Texas

Pedernales Electric Cooperative distributed generation

Their own published program, read and recorded. This outranks the Texas state rule wherever the two differ, because it is the program this utility actually administers.

How the size is measured

the aggregated nameplate capacity in kW AC at a single point of interconnection. PEC states every tier in AC explicitly and aggregates across the site, which makes it the clearest AC basis in the region.

Size bands and what each one obliges

Tier I, under 50 kW AC Size 0 to 49.999 kW

A $500 non refundable fee applies, plus the actual cost of any system upgrades. No liability insurance is required; the agreement only says the member may consider obtaining it. The residential Sustainable Power Credit buyback rate applies at this size.

  • $500 non refundable application fee, billed on the next cycle
  • Visible, lockable, labeled, fused disconnect within 10 feet of the point of interconnection
  • Member signature on the interconnection agreement
Tier II, 50 kW AC to under 1 MW Size 50 to 999.999 kW

A $700 non refundable fee applies, plus the actual cost of engineering study coordination and system upgrades. Compensation moves off the residential Sustainable Power Credit and onto the Interconnect Wholesale Energy Rate.

  • $700 non refundable application fee
  • Engineering study coordination at actual cost
  • Visible, lockable, labeled, fused disconnect
Tier III, 1 MW to 10 MW Size 1000 to 10000 kW

A $2,500 non refundable fee applies, plus the actual cost of engineering study coordination and system upgrades.

  • $2,500 non refundable application fee
  • Engineering study coordination at actual cost

The screens that decide it

Ask the utility this, before you sell it

  1. PEC publishes no percentage of annual consumption cap and no percentage of service rating cap. Confirm whether either is applied in practice at this address.
  2. PEC publishes a separate Requirements for Standby Generation document. If a battery is included, ask which document governs it and whether a non export configuration is required.
  3. What is the current queue time? PEC publishes an overall estimate of four to six weeks and 10 to 15 business days for final inspection, but no binding clock on design review.

Worth knowing before you quote

Two costs an installer must carry into the quote. The disconnect must be visible, lockable, labeled and fused, within 10 feet of the point of interconnection, and within line of sight of the meter or accompanied by a map placard at the meter. A monthly Service Availability Charge applies to every DG account: $32.50 residential, $37.50 small power single phase, $57.50 three phase. And PEC states plainly that installers are not permitted to sign the interconnection agreement or the member acknowledgement form on the member’s behalf. The installer may submit; the member must sign. A modification under 50 kW carries a $250 fee.

Pedernales Electric Cooperative Interconnection Agreement for Parallel Operation of Distributed Generation, with the published Interconnection Process fee tiers and the DG Interconnection Rates schedule

Read and recorded 2026-09-12. Rural electric cooperative, outside the Texas interconnection standard. The cooperative's own published documents govern. PEC adopts PUCT Substantive Rule 25.212 by contract for safety and operation. That is the technical rule, not the interconnection and screening rule 25.211, so no state screen framework is incorporated. The agreement itself carries no printed effective date.
