Two Potential “Firsts”: Proposed GA Law Would Permit Utility Tariff Bonds for Coal Combustion Residuals (aka Coal Ash) Remediation and Nuclear Construction Delays and Cost Overruns


Under Senate Bill 421, a new Chapter 3B—to be called the Georgia Utility Rate Reduction Act (GURRA)—would be added to Title 46 of the Georgia Official Code.

Under GURRA, a utility could apply for, and may obtain, a financing order from the Georgia Public Service Commission (GA PSC) to authorize such utility to charge its customers for GURRA-eligible projects that include:

  • A new nuclear unit;
  • A retired electrical generating unit with remaining book value necessitating the continued collection of revenue from customers; or
  • Capital construction associated with cleanup or remediation of any coal combustion residuals (CCRs).

While other states1 have laws that permit a utility to recover the undepreciated value of retired fossil-fired generation, none have permitted new nuclear construction2 or CCR remediation to be funded by utility tariff bonds.3

While using utility tariff bonds to fund nuclear construction delays and cost overruns would mean that the utility applicant would have to forgo equity return on the related investment, at least recovery would be assured and related customer “rate shock” impact mitigated.

Recent cost estimates for utility coal ash remediation are substantial. For example, in Alabama, Alabama Power’s estimate for coal ash cleanup is around $3.3 billion; in Georgia, Georgia Power’s estimate is $9 billion; and in North Carolina, Duke Energy’s estimate ranges between $8 and $9.5 billion. Given the magnitude of these related costs, it is likely that other states with coal-fired generation and related coal ash ponds will follow and enact similar legislation.



1 These include Colorado, Montana and New Mexico, and other states have considered similar legislation.

2 Florida had a law that permitted utility tariff bonds to recover nuclear abandonment costs. This law was used for the proposed Crystal River 3 nuclear unit. A similar law was proposed in South Carolina for the VC Summer plant but was not passed.
