New Jersey has four natural gas utilities: PSE&G Gas, New Jersey Natural Gas (NJNG), Elizabethtown Gas, South Jersey Gas. Each has its own default rate. Supplier choice runs through the BPU for all four. A single TPS can be authorized across multiple utilities, but residents must enroll on each one separately. Locked gas supplier rates typically save 12 to 22 percent vs utility default over a 24-month term.

South Jersey Gas serves the southern third of the state including Atlantic, Cumberland, and surrounding counties.
Default rate spread across four utilities
2026 NJ gas defaults: PSE&G Gas around $0.84 per therm, NJNG around $0.78, Elizabethtown around $0.92, South Jersey Gas around $0.86. Spread reflects different procurement costs and pipeline capacity allocations.
Locked supplier rates typically come in 12 to 22 percent below the utility default across all four. The supplier list size varies; PSE&G and NJNG have the largest lists with 15+ active TPS each.
Cross-utility TPS rules
A single TPS can be BPU-certified to serve multiple NJ gas utilities. The TPS offers different pricing for each utility because capacity charges and procurement costs differ.
