North Carolina commercial energy strategy operates under a regulated structure dominated by Duke Energy's two operating companies (Duke Energy Carolinas in the western and central state, Duke Energy Progress in the east) plus Dominion Energy North Carolina in the northeast and a network of municipal systems through ElectriCities. Duke's commercial tariff books (SGS, MGS, LGS, OPT on each operating company) set distinct demand structures by account class; schedule election produces structural savings on accounts that have grown past their original tariff classification. Duke PowerShare demand response pays monthly demand credits for committed curtailment during dispatched events. The North Carolina Manufacturers Sales Tax Exemption on qualifying utility usage is a parallel recovery track. Piedmont Natural Gas (now under Duke Energy) handles most commercial gas service; commercial rates 102, 121, 125 set the structure. Developments CS works across both Duke operating companies, Dominion NC, and the municipal systems with tariff classification, PowerShare enrollment, and manufacturing tax exemption as the standard engagement scope.
Major utilities we work with
Utilities we track in North Carolina
Each utility carries its own tariff book, demand structure, and program environment. The engagement maps every account against every applicable schedule.
Duke Energy Carolinas
electricElectric distribution across the Western and Piedmont regions of North Carolina (Charlotte and Greensboro metros, much of the western and central state). Commercial tariff schedules SGS, MGS, LGS, OPT carry distinct structures.
Duke Energy Progress
electricElectric distribution across Eastern and parts of Central North Carolina (Raleigh-Durham metro, Wilmington, Eastern NC). Commercial tariffs SGS, MGS, LGS, OPT-D, OPT-G set the structure; rate structures differ from Duke Carolinas.
Dominion Energy North Carolina
electricElectric distribution in Northeast North Carolina, plus Roanoke Rapids area. Smaller footprint but commercial tariffs distinct from Duke service.
ElectriCities of North Carolina (municipal systems)
electricNetwork of municipal electric systems across North Carolina (Greenville, Wilson, High Point, Concord, others). Each runs its own commercial rate structure.
Piedmont Natural Gas (Duke Energy)
gasNatural gas distribution across most of North Carolina. Commercial rate schedules 102, 121, 125 carry distinct structures for commercial and industrial accounts.
Dominion Energy North Carolina (gas)
gasNatural gas distribution in parts of the state outside Piedmont's footprint. Commercial rates set the structure separately from electric service.
Programs we capture
Key North Carolina programs the engagement stacks into
State and utility programs that stack with the underlying tariff and procurement work to compound the annualized recovery.
- Rebate
Duke Energy Smart Saver for Business
Duke Energy commercial efficiency program (operating across both Carolinas operating companies). Prescriptive rebates plus custom incentives on engineered projects; coverage levels in the 25 to 45 percent range of project cost on qualifying measures.
- Demand response
Duke Energy PowerShare demand response
Duke Energy commercial demand response program in North Carolina. Pays monthly demand credits for committed curtailment during dispatched events; commercial sites with at least 200 kW of dispatchable load qualify.
- Rebate
North Carolina Solar Rebate Program (legacy / successor)
Duke Energy Carolinas and Duke Energy Progress solar rebate programs. The original NC rebate program closed; successor structure under HB 951 sets compensation for new commercial behind-the-meter solar projects.
- Tax credit
North Carolina Manufacturers Sales Tax Exemption
North Carolina exempts qualifying manufacturing usage of electricity, fuel, and certain other utilities from state sales tax. Requires documentation of qualifying manufacturing use and a properly filed exemption certificate.
- Rebate
North Carolina Department of Environmental Quality energy programs
State agency programs supporting commercial efficiency and renewable energy projects. Funding cycles and scope vary.
- Tax credit
Federal Production Tax Credit for solar (PTC option)
Commercial solar projects in North Carolina can elect between the Investment Tax Credit and the Production Tax Credit under the IRA. The PTC may be more favorable on large-scale or high-capacity-factor installations.
What an engagement looks like
How a North Carolina engagement runs
A North Carolina engagement opens with the Duke Energy tariff classification review. Duke Energy Carolinas and Duke Energy Progress carry parallel but distinct tariff books; the schedule that should be on each account depends on the demand profile, load factor, and service voltage. SGS (small), MGS (medium), LGS (large), and OPT (optional time-of-use) each fit specific profiles; the first deliverable is a twelve-month interval analysis against every eligible schedule.
Duke PowerShare enrollment is the second lever. Any commercial site with at least 200 kW of dispatchable load qualifies for monthly demand credits in exchange for committed curtailment during dispatched events. Average dispatch frequency runs two events per year; well-coordinated operations absorb the curtailment cleanly.
For manufacturing operators, the North Carolina sales tax exemption track runs in parallel. A utility study quantifies the qualifying manufacturing use percentage; the exemption certificate is filed with the utility and with the NC Department of Revenue. Back-credit recovery on prior overpayments is available within the applicable statute. Piedmont Natural Gas (now under Duke Energy) handles most commercial gas service; the tariff classification analysis on the gas side runs in parallel with the electric work.
Sample finding patterns
What the pipeline catches in North Carolina
Plausible examples drawn from the pattern types most commonly caught in North Carolina. Specific clients are not named; utilities, tariff codes, and recovery ranges are. Recovery ranges are stated as ranges (typically the 25th to 75th percentile of the relevant cohort), never as point estimates.
Tariff schedule election
Duke Energy Carolinas · MGS vs LGSA Charlotte-area distribution center on Duke Energy Carolinas MGS (medium general service) had grown into a demand profile that fit LGS (large general service). The schedule election produced a structural reduction in the demand charge component; the load factor on the account supported the LGS structure cleanly.
PowerShare enrollment
Duke Energy ProgressA Wilmington-area manufacturing facility with 1.0 MW of dispatchable load had never enrolled in Duke PowerShare. Enrollment produced monthly demand credits running roughly $4 per kW per month on committed load. Two dispatch events per year on average; production scheduling absorbed the curtailment.
Manufacturing sales tax exemption
Duke Energy Carolinas and Piedmont Natural GasA North Carolina furniture manufacturer had never filed for the state sales tax exemption on its electric and gas service. A utility study quantified the qualifying manufacturing use percentage above the exemption threshold. The exemption certificate filings and back-credit pursuit on prior overpayments covered the NC Department of Revenue statute.
Demand profile management
Duke Energy Carolinas · OPT (optional time-of-use)A Greensboro-area commercial building on Duke Carolinas OPT had on-peak demand windows landing during normal occupied hours without adjustments to operations. Shifting HVAC pre-cool to off-peak periods and tightening setpoint control during on-peak windows cut the on-peak demand by roughly 22 percent without changing occupant comfort. The demand charge component dropped accordingly.

Where to next
The disciplines that drive the work in North Carolina
The North Carolina engagement runs across all our standard service lines. Tariff and rate audits and billing forensics produce the immediate-cycle bill corrections; demand management and supply procurement cut the structural cost base; incentives and grants stack utility and state program funding into capital projects; tax and fee recovery surfaces back-credit on prior overpayments where qualifying use applies.
