Duke Energy Carolinas and Public Staff Reach Rate Settlement; State Attorney General Declines to Join
A proposed North Carolina settlement would cut Duke Energy Carolinas' rate-hike request and lower its allowed profit rate, but the state's attorney general says the increase is still too high.
The Deal
Duke Energy Carolinas supplies electricity to much of western and central North Carolina, including Charlotte. Last fall, it asked state regulators for a big rate increase — up to about 18% for a typical home over two years[1][7].
On July 18, 2026, the company filed a proposed settlement with the North Carolina Utilities Commission[1][2]. The Public Staff, the state agency that represents customers, signed on. So did Walmart, industrial customer groups, and the North Carolina Sustainable Energy Association[1][2].
The deal would cut the increase roughly in half, to about 9.5% over two years[3][5]. It also lowers the profit rate regulators let Duke earn. Under the settlement, a typical bill rises about $9.39 a month in 2027 and another $5.52 a month in 2028[3].
The settlement is not final. North Carolina Attorney General Jeff Jackson, a Democrat, announced on July 21 that his office would not join it[5][6]. The five-member Utilities Commission, whose members are appointed by the governor, is expected to rule later in 2026[3].
What Both Sides Agree On
Some facts here are not in dispute. Duke's original request, filed in fall 2025, sought up to an 18% residential increase over two years[1][7]. The company had already lowered that to 11.6% in June 2026, before cutting further in the settlement[3][9].
The settlement sets the company's allowed return on equity at 9.8%, down from Duke's original ask of 10.95%[5]. It also sets a 53% "equity ratio," a separate number covered below[5].
Duke shareholders, not customers, will contribute $10 million to two low-income bill-assistance programs, Share the Light and the Helping Home Fund[1][3]. And the settlement does not resolve everything: a separate rate case involving Duke Energy Progress, which serves eastern North Carolina and Raleigh, is still being contested[2][3][8].
The Number at the Center of the Fight
The whole dispute turns on one figure: return on equity, or ROE. It sounds technical, but the idea is simple. Duke is a monopoly — customers cannot switch providers — so regulators, not competition, decide how much profit it is allowed to earn on the money its shareholders have invested in the grid[3].
Set that number too low, and investors have less reason to keep putting money into Duke instead of some other company. That can hurt Duke's credit rating, which in turn raises its cost of borrowing. Duke argues those higher borrowing costs eventually get passed on to customers anyway[1][5]. Set the number too high, and customers pay more today so shareholders earn more.
Duke first asked for 10.95%. The settlement lands at 9.8%[5]. Attorney General Jackson argues the fair number is 7.4%, and his office's experts estimate that lower rate would save customers about $1.37 billion over two years[6].
The settlement's other headline figure, the 53% equity ratio, works alongside ROE. It sets the share of Duke's grid investment that comes from shareholder money rather than borrowed money[5]. Equity is more expensive than debt, because shareholders demand a higher return for the risk they take on. A higher equity ratio pushes bills up for the same reason a higher ROE does — but Duke says it also protects the company's credit rating, which it argues keeps future borrowing, and future bills, lower[1][5].
The Pressure Underneath
Duke is legally required to keep the grid reliable, and that grid is expensive to maintain and expand. The ROE is the tool it has to attract the outside investment that pays for it, so the company has a direct financial interest in keeping that number as high as it can defend[1][10].
A big driver of the coming costs is demand growth. Duke reports 7.6 gigawatts of signed data-center contracts and a five-year, $103 billion plan to build out the grid[6][10]. Someone has to pay for that. The core disagreement is whether households should shoulder a large share of costs driven mainly by data centers and heavy industry[6].
There is also a political dimension. An elected attorney general benefits from being seen as the person who cut a big utility bill. A settlement gives the Public Staff a certain, negotiated result instead of the risk of a worse outcome after a long fight before the Commission[5][6].
Whatever the Commission ultimately decides, one thing will not change: Duke Energy Carolinas customers will pay more than they do now. The only question is how much more. The gap between the settlement's 9.8% ROE and the attorney general's preferred 7.4% is worth roughly a billion dollars to customers over two years, by the AG's own estimate — and a comparable amount in profit to Duke[3][6].
How Each Side Sees It
Duke frames the settlement as a "lower-cost path" to a more reliable grid[1]. The company says a regulated monopoly cannot raise money the way an ordinary business does, so a competitive, predictable return is what lets it keep drawing outside investment. It also points to features like refunds if promised upgrades run late[1][2].
The Public Staff and the customer groups that signed on — including Walmart, industrial users, and clean-energy advocates — argue the deal is a concrete win. It cuts Duke's original ask by more than half and lowers the profit rate, they say, without the risk of a worse result from a contested Commission ruling[1][3]. Large industrial and retail buyers also value the rate certainty a settlement provides[3].
Attorney General Jackson calls the settlement "progress" but says it still asks too much of families[5][6]. He argues a 7.4% ROE is the fair number and points to his estimate of $1.37 billion in savings over two years[6]. He frames the fight, in both this case and the pending Duke Energy Progress case, as a question of whether households should pay for growth driven by data centers[6][8].
The Utilities Commission sits between these positions. By law, it must set rates that are "just and reasonable" — high enough to keep the utility financially sound, low enough to be fair to customers[3]. Its ruling, expected later this year, will set the actual rates millions of North Carolinians pay.
How the Coverage Split
Coverage of the settlement varied by outlet in ways that tracked familiar lines. Duke's own press release led with reliability and a "lower-cost path," emphasizing the size of the cut without stating the dollar amount customers will still pay[1].
Public radio outlets like WFAE framed the story around Duke "halving" its request, giving more weight to the concession and to praise from groups like the North Carolina League of Conservation Voters[3]. Right-leaning and local Fox-affiliate coverage, including Fox Carolina and WLOS, led instead with the attorney general's rejection and the 9.5% bill increase still ahead, foregrounding the data-center question of who should pay for growth.
The North Carolina Department of Justice's own release cast Jackson's office as fighting to "save" families money, presenting its $1.37 billion estimate — which depends on its preferred 7.4% ROE — as a near-certain outcome[6]. Business-oriented outlets like Business North Carolina and Axios stayed closer to neutral, procedural language, describing an "agreement" or a "lower" increase without emphasizing either the concession or the pushback[4][9].
Outside the United States, the story drew almost no dedicated coverage. The only overseas or non-Western attention came from financial aggregators treating it purely as a data point for Duke's stock, with no attention to what customers would actually pay.
Summary
Duke Energy Carolinas is the utility that supplies power to much of the western and central part of North Carolina, including Charlotte. In late 2025 it asked state regulators for a large rate increase — up to about 18% for a typical home over two years[1][7]. On July 18, 2026, the company filed a proposed settlement with the North Carolina Utilities Commission Public Staff — the state agency that represents utility customers — and other parties, including Walmart, big industrial users, and clean-energy groups[1][2]. The deal would cut the increase to about 9.5% for a home over two years and lower the profit rate Duke is allowed to earn[3][5].
The heart of the deal is a number called return on equity, or ROE. That is the profit rate regulators let a monopoly utility earn on the money shareholders put in. Duke first asked for 10.95%. The settlement drops it to 9.8%[5]. A lower ROE means smaller profits for Duke and a smaller bill for customers[3]. The settlement also sets a 53% 'equity ratio' — the share of Duke's grid investment financed by shareholder equity rather than debt[5]. Equity costs more than debt, since shareholders demand a higher return for the risk they take on, so a higher equity ratio pushes the overall bill up; Duke argues it also protects the company's credit rating, which keeps its borrowing costs — and future bills — lower[1][5].
But the settlement is not final, and it is not agreed by everyone. North Carolina Attorney General Jeff Jackson, a Democrat, said on July 21 that his office will not sign it[5][6]. He argues the profit rate should be 7.4%, which his experts estimate would save customers about $1.37 billion over two years[6]. Jackson called the smaller increase 'progress' but said it still asks too much of families, some of it to serve fast-growing data centers[5][6]. The five-member Utilities Commission — whose members are appointed by the governor — will decide later this year whether to approve the deal[3]. A separate case involving Duke's other North Carolina unit, Duke Energy Progress, covering eastern North Carolina and Raleigh, is still being fought over[3][8].
The Event
On July 18, 2026, Duke Energy Carolinas filed a proposed settlement with the North Carolina Utilities Commission, joined by the Commission's Public Staff, Walmart, industrial customer groups, and the North Carolina Sustainable Energy Association, among others[1][2]. The agreement would set an allowed return on equity of 9.8% and a 53% equity ratio, cutting the company's rate request to about a 9.5% residential increase over two years from an original request of roughly 18%[3][5]. On July 21, North Carolina Attorney General Jeff Jackson announced his office would not join the settlement and would keep contesting the case[5][6]. The Utilities Commission is expected to rule later in 2026[3].
Undisputed Facts
- Duke Energy Carolinas originally sought a residential rate increase of up to about 18% over two years, filed in fall 2025[1][7].
- The company lowered its request to 11.6% in June 2026, then to the settlement level in July[3][9].
- The proposed settlement sets return on equity at 9.8%, down from an original request of 10.95%, with a 53% equity ratio[5].
- Under the settlement, a typical residential bill would rise about $9.39 a month in 2027 and about $5.52 a month in 2028[3].
- Signers include the NC Utilities Commission Public Staff, Walmart, the Carolina Industrial Group for Fair Utility Rates, the Carolina Utility Customers Association, and the North Carolina Sustainable Energy Association[1][2].
- The settlement asks Duke shareholders — not customers — to contribute $10 million to two low-income bill-assistance programs, Share the Light and the Helping Home Fund[1][3].
- North Carolina Attorney General Jeff Jackson declined to join the settlement and supports a 7.4% return on equity[5][6].
- The settlement requires approval by the five-member North Carolina Utilities Commission and does not resolve the separate Duke Energy Progress rate case[2][3][8].
The Pressure
Strip away the moralizing and blame. What structural realities persist regardless of which narrative wins?
- Financing a monopoly grid
- Duke must raise large amounts of capital for a fixed grid it is legally obliged to keep reliable. The allowed return on equity is the lever that sets both its profit and its cost of capital, so it fights hardest there[1][10].
- Demand is surging from data centers
- Duke reports 7.6 gigawatts of signed data-center contracts and a $103 billion five-year build plan. Someone must pay for that buildout — the fight is whether households or the large users driving the growth carry more of it[6][10].
- Electoral consumer politics
- An elected attorney general gains politically by visibly cutting bills; a negotiated settlement gives the Public Staff a guaranteed, defensible result. Both are shaped by wanting a win they can point to[5][6].
Material realityWhatever the Commission decides, Duke Energy Carolinas customers will pay more than they do now — the dispute is only about how much. The settlement's 9.8% ROE versus the attorney general's 7.4% is a gap worth roughly a billion dollars to customers over two years by the AG's own estimate, and a similar amount in profit to Duke[3][6]. The grid buildout for data centers and industry is already underway and will be funded from rates one way or another[10].
Narrative as a weaponTwo actors are working hardest to shape perception. Duke wants you to see a company voluntarily cutting its request in half to fund a reliable future, so it leads with the concession and buries the remaining dollar increase. Attorney General Jackson wants you to see a still-too-high bill that families pay to power data centers, so he leads with a big savings figure — one that assumes his preferred profit rate wins. The Public Staff, sitting between them, wants the settlement read as a solid, certain win rather than a compromise. Most local news split the difference by treating the AG's rejection as the news hook.
How Each Side Sees It
Each major actor’s view — how it frames things, its underlying incentive, and how it’s materially affected. Tap a side to read it.
Frames it asDuke argues a regulated monopoly cannot raise money the way a normal company does — it must attract outside investors to fund a grid that has to stay reliable. A fair, competitive return on equity is how it draws that money. Set the return too low and its credit rating can slip; borrowing then costs more, and customers pay for that costlier debt later. Duke frames the deal as a 'lower-cost path' that still lets it build for surging demand, including from data centers, while giving customers a refund if promised upgrades run late[1][2].
WhyMaximize the allowed profit rate and lock in revenue certainty for a $103 billion five-year building plan, while avoiding a bruising, unpredictable fight before the Commission[1][10].
Impact on themA higher ROE directly raises Duke's regulated earnings; even the gap between 9.8% and 7.4% is worth hundreds of millions a year in profit and shapes its stock and credit outlook[6][10].
Frames it asThe Public Staff, the state agency assigned to represent ratepayers, argues a negotiated deal that cuts the increase by more than half and lowers the profit rate is a concrete, certain win — better than gambling on a contested ruling that could land higher. Big buyers like Walmart and industrial users want predictable rates. Clean-energy groups point to refund protections and low-income funds as real gains[1][3].
WhyLock in immediate, guaranteed savings and rate certainty rather than risk a worse or slower outcome in full litigation[1][3].
Impact on themMembers get lower bills than Duke first sought; large industrial and retail customers get predictable costs for planning[3].
Frames it asJackson argues the settlement, while an improvement, still overcharges families. His experts testified a 7.4% return on equity is fair and would save customers about $1.37 billion over two years[6]. He frames the core question as who pays for growth: he says households should not shoulder costs driven by data centers and heavy industry. He is fighting the same fight in the separate Duke Energy Progress case, where he estimates another $960 million at stake[6][8].
WhyDeliver measurable consumer savings and position himself, as an elected Democrat, as a check on utility profits[6][8].
Impact on themBy staying out, he keeps the ROE issue live before the Commission and can appeal an unfavorable order[5][6].
Frames it asThe Commission is the referee. It must weigh a settlement backed by most parties against the attorney general's objection, and by law set rates that are 'just and reasonable' — high enough to keep the utility financially healthy, low enough to be fair to customers[3].
WhyProduce a defensible order that keeps the grid financed and survives appeal[3].
Impact on themIts ruling, expected later in 2026, sets the actual rates millions of customers pay[3].
