How This Was Decided

These companies are featured based on what matters for this category:

  • Effective rate at 2,000-3,000 kWh usage levels after all credits and fees
  • Bill credit structure and threshold consistency with high-usage patterns
  • Base energy charge competitiveness for sustained high consumption
  • Contract flexibility and renewal terms for long-term cost predictability
  • Free nights/weekends options that reward usage-shifting behavior

No bias. Same treatment for every company.
