Introduction

Duquesne Light Company serves approximately 600,000 customers across 817 square miles of Allegheny and Beaver counties, including the City of Pittsburgh, the surrounding suburbs of the Pittsburgh metro, and the smaller communities along the Ohio border. As of early 2026, the average all-in DLC residential rate is approximately 23.1 cents per kWh, the highest of any major Pennsylvania utility. PECO sits at roughly 20 cents. PPL is at 19.2 cents. Met-Ed is at 19 cents. Penelec, the second-most-expensive PA utility, charges 21.1 cents. Pittsburgh pays the most.

Pittsburgh’s rate position is not a temporary blip. It is a function of legacy industrial infrastructure recovery, ongoing grid modernization investment, a customer base smaller than the major eastern Pennsylvania utilities, and the same PJM wholesale capacity cost pressure that is hitting every utility in the region. In December 2025, DLC took the largest single-utility supply rate increase of any major PA utility, raising the residential Price to Compare 10.6 percent in a single reset.

This guide breaks down what Duquesne Light residential customers are actually paying in 2026, the regulatory and ownership structure that makes DLC unique among PA utilities, what the expanded Time of Use program offers, and what homeowners can do about a rate trajectory that is unlikely to reverse.

What Duquesne Light Customers Are Paying in 2026

As of April 2026, the average all-in Duquesne Light residential rate, covering generation supply, distribution, transmission, and riders, is approximately 23.1 cents per kWh.

The supply side of that total is set by DLC’s Price to Compare, which resets every June 1 and December 1:

• December 1, 2024 PTC: 8.4472 cents per kWh
• June 1, 2025 PTC: 9.7093 cents per kWh (up 14.9 percent)
• June 1, 2025 PTC (revised, includes transmission): 12.43 cents per kWh
• December 1, 2025 PTC: 13.75 cents per kWh (up 10.6 percent from prior)

The December 1, 2025 increase was the steepest single-reset PTC change of any major PA utility. For comparison, the FirstEnergy PA utilities saw December 2025 PTC increases of 6.1 to 8.9 percent, and PECO and PPL saw smaller adjustments under their respective procurement schedules.

On the distribution side, DLC’s last rate increase took effect December 20, 2024 under the PUC-approved 2024 base rate case settlement. For an average residential customer using 600 kWh per month, the total monthly bill increased from $130.67 to $135.88, or 3.99 percent.

The next DLC PTC reset is scheduled for June 1, 2026. The resulting rate will reflect the PJM capacity auction that cleared in July 2025 at the FERC-approved price cap of $329.17 per megawatt-day, along with updated wholesale generation and transmission costs.

Why Pittsburgh Pays the Highest Residential Rate in Pennsylvania

Three structural factors converge to put Duquesne Light at the top of the PA rate stack.

A Smaller Customer Base for Fixed Cost Recovery

DLC’s service territory is small in physical area, just 817 square miles, but moderately populous, with approximately 600,000 customers. Compare this to PECO (1.7 million customers, 2,100 sq mi), PPL (1.5 million customers, 10,000 sq mi), and Penelec (597,000 customers, 17,600 sq mi). On a customer count basis, DLC has one of the smaller ratepayer bases in the state.

When a utility files a base rate case, the requested revenue increase is allocated across that customer base. A smaller base means each customer’s share of fixed cost recovery is larger, all else equal. DLC’s distribution rates reflect this math, and so does the per-customer cost of any major infrastructure investment program.

Legacy Industrial Infrastructure

Pittsburgh’s electrical grid was built to serve heavy industry. Steel, glass, and manufacturing dominated the regional economy for most of the 20th century, and the transmission and distribution system was sized accordingly. The deindustrialization of the Pittsburgh metro starting in the 1980s left DLC with infrastructure designed for one demand profile but serving a substantially different one.

Maintaining and modernizing that legacy infrastructure for a smaller, less industrial customer base is expensive. DLC’s distribution system includes more than 45,000 miles of overhead lines, a substantial network for the customer count it serves. Aging substations, transmission corridors, and the ongoing investment required to keep them reliable feed directly into the distribution rate base.

PJM Wholesale Pressure on a Smaller Base

DLC sits within the PJM Interconnection footprint, the same regional grid operator that serves PECO, PPL, Met-Ed, Penelec, PSE&G, JCP&L, and every other utility across 13 states. The PJM capacity market has driven supply rate increases across all of them. But DLC’s December 2025 PTC jump of 10.6 percent was the largest in the state.

That is partly a function of timing. DLC’s procurement cycle aligned with the period when the highest-priced PJM capacity auction results were flowing through. It is also partly a function of which generation portfolio mix was being reflected in the most recent procurement window. The mechanics of the wholesale pass-through are the same as every other PA utility; the magnitude of any single reset depends on what supply contracts are rolling over and what new ones are being priced.

The combined effect of these three factors is what produces the all-in 23.1 cents per kWh. Each factor on its own would not be enough. Together they put Pittsburgh at the top.

The Ownership Structure That Sets DLC Apart

Duquesne Light is the only major Pennsylvania investor-owned electric utility under private equity and institutional fund ownership rather than public-company ownership. This is unusual enough among PA utilities that it deserves a clear explanation, because it shapes how DLC capital decisions get made and how rate cases get argued.

The chain of ownership runs as follows:

• Duquesne Light Company (the operating utility, regulated by the PA PUC)
• is wholly owned by Duquesne Light Holdings, Inc. (the holding company)
• which is wholly owned by DQE Holdings LLC (the parent entity)
• which is owned by a consortium of institutional and infrastructure investors

In May 2007, the previous publicly traded DQE Inc. was taken private by a consortium led by affiliates of the Australian-based Macquarie Group, in an all-cash transaction at $20 per share. Duquesne Light has been under this ownership structure ever since. The current consortium, based on PUC filings, includes:

• The Government of Singapore Investment Corporation (GIC)
• Macquarie Infrastructure Partners (through CLH Holdings)
• Industry Funds Management (through IFM Global Infrastructure)
• Dutch pension fund manager PGGM (through Three Rivers Utility Holdings)
• John Hancock Life Insurance
• Australian superannuation funds including First State Super and State Super

For comparison: PECO is owned by Exelon Corporation (publicly traded NASDAQ: EXC). PPL Corporation is publicly traded (NYSE: PPL). Met-Ed and Penelec are subsidiaries of FirstEnergy Corp. (publicly traded NYSE: FE). Every other major PA utility is part of a publicly traded corporate parent.

The practical implications for DLC ratepayers:

• Ownership stability under long-term institutional investors typically produces a more capital-intensive infrastructure investment posture, since the ownership horizon is multi-decade
• Capital structure decisions are made by the parent consortium rather than by public-equity markets, which can affect financing costs that flow into rate cases
• Settlement dynamics in rate cases tend toward predictable, infrastructure-investment-heavy outcomes because the consortium ownership is reliability-oriented and modernization-oriented

DLC’s headquarters remain in Pittsburgh. The utility employs local field crews and operates as a Pennsylvania regulated entity under the PA PUC. The ownership structure does not change how rates are filed or approved. But it is a real distinction from every other PA utility, and it is one of the reasons DLC tends to pursue ambitious modernization programs, including its expanded Time of Use offering.

The Duquesne Light 2024 Rate Case

In March 2024, DLC filed a base distribution rate case at the PA PUC seeking $133 million in additional annual revenue (or $101 million net of revenues already recovered through existing surcharges). The proposed bill impact for an average residential customer using 600 kWh per month would have been a 6.52 percent total bill increase.

After seven months of PUC proceedings, a joint settlement was reached and approved by the PUC on November 7, 2024. The final terms:

• $74.2 million net increase in annual operating revenues, a roughly 50 percent reduction from the originally requested $115 million
• $85.1 million total in distribution operating revenue when the $32.1 million in rolled-in surcharges is included
• Average residential customer (600 kWh/month) bill increase: $130.67 to $135.88, or 3.99 percent
• Effective date: December 20, 2024
• DLC barred from filing another base distribution rate case before March 20, 2026

Settlement provisions beyond the rate change:

• Auto-recertification of customer assistance program enrollees using LIHEAP data
• $300,000 per year increase in the Smart Comfort Low Income Usage Reduction Program (LIURP), bringing the total annual budget to $3.75 million
• $350,000 per year in shareholder funding to the Hardship Fund for 2025, 2026, and 2027
• Approval of expanded electric vehicle Time of Use rates and Transportation Electrification programs (Community, Fleet, and Transit pilot programs)

The settlement was supported by the PA Office of Consumer Advocate, the Office of Small Business Advocate, the Coalition for Affordable Utility Services and Energy Efficiency in Pennsylvania, the Pennsylvania Weatherization Providers Task Force, Walmart, the PUC’s independent Bureau of Investigation and Enforcement, and DLC. The PUC vote was unanimous (5-0).

The “stay-out” provision means DLC cannot file a new base rate case before March 20, 2026, and the standard seven-month PUC investigation timeline means any new distribution rate increase from a fresh filing would not take effect before late 2026 or early 2027.

The Expanded Time of Use Program

In April 2025, the PA PUC unanimously approved an expansion of DLC’s Time of Use (TOU) pilot program, making it available to all residential and small commercial default-service customers with smart meters. Previously the pilot was restricted to EV owners only. This was the first PA utility to offer broad TOU access to its general default-service residential population.

How TOU works in DLC territory:

• Off-peak rates (typically overnight and midday hours): lower than the standard PTC
• On-peak rates (typically late afternoon and evening hours): higher than the standard PTC
• Total cost depends on the share of usage that falls in each window

For households that can shift significant load to off-peak hours, EV charging, dishwashers, laundry, water heating, and clothes dryers running on timers, TOU can reduce effective rates meaningfully. For households that cannot shift usage, especially those with heavy peak-evening cooking, lighting, and air conditioning loads in summer, TOU often costs more than staying on the standard PTC.

For solar customers with battery storage, TOU rates can also reshape the economics of when stored energy is most valuable. Discharging a battery during the on-peak window when grid rates are highest produces a larger effective bill offset than discharging at midday when rates are lower.

The TOU expansion is not a rate increase. It is an opt-in alternative for customers who want to manage their bills through usage timing rather than through the standard PTC.

Breaking Down Your Duquesne Light Bill

Your DLC bill has two main components, and each one responds to different forces.

Distribution Charges

These are the fixed-rate charges for delivering electricity through DLC’s local infrastructure. Distribution rates are set by the Pennsylvania PUC in periodic base rate cases.

The current DLC distribution rates took effect December 20, 2024 under the 2024 base rate case settlement. These rates are stable until DLC’s next base rate case takes effect, which cannot happen before late 2026 or early 2027 given the March 20, 2026 stay-out provision and the seven-month PUC investigation timeline.

Supply Charges (Price to Compare)

This is the portion of your bill that covers the actual electricity you consume. DLC’s Price to Compare resets every June 1 and December 1, reflecting PJM wholesale generation costs plus transmission.

As of December 1, 2025, the DLC residential PTC is 13.75 cents per kWh. The next reset is scheduled for June 1, 2026.

You can change this portion of the bill by switching to a competitive electricity supplier through PAPowerSwitch.com, by enrolling in the expanded TOU pilot, or by generating your own power with solar.

Riders and Other Charges

On top of distribution and supply, your DLC bill includes:

• State Tax Adjustment Surcharge
• Distribution System Improvement Charge (DSIC)
• Act 129 Energy Efficiency Surcharge
• Universal Service Rider (funds low-income assistance)
• Default Service Supply Rider
• Smart Meter Rider

These riders are typically small individually but collectively contribute to the gap between the headline PTC and the all-in 23.1 cents per kWh.

How Duquesne Light Rates Compare Across Pennsylvania

DLC sits at the top of the PA utility rate spectrum as of early 2026:

Utility	Service Territory	All-In Residential Rate
Duquesne Light	Southwestern PA (Pittsburgh)	~23.1¢/kWh
Penelec	Northern/western PA	~21.1¢/kWh
PECO	Southeastern PA (Philadelphia)	~20.0¢/kWh
PPL Electric	Central/eastern PA	~19.2¢/kWh
Met-Ed	Eastern PA (Reading, Lehigh edge)	~19.0¢/kWh

The ranking is current but fluid. DLC’s next base rate case (earliest filing March 20, 2026) will reshape its distribution rates, and the June 2026 PTC reset will reflect the next round of PJM wholesale costs. PPL’s pending $275 million distribution rate settlement, taking effect July 1, 2026, will move PPL up the rate stack. Whatever the next twelve months produce, DLC is unlikely to fall below the top two.

What Options Do Duquesne Light Customers Have?

Pennsylvania’s deregulated market gives DLC customers four real paths to reducing or stabilizing electricity costs. With the highest all-in rate in the state, the value of each option is greater for DLC customers than for customers of any other major PA utility.

Shop for a Competitive Supplier

Through PAPowerSwitch.com, residential customers can compare fixed-rate and variable-rate plans from licensed electric generation suppliers. Fixed-term contracts protect against future PTC increases for 12 to 36 months. At DLC’s current 13.75 cent PTC and a trajectory that has moved only upward, locking in a fixed rate below the PTC has real defensive value.

The tradeoff: competitive supplier plans typically carry early termination fees, and a fixed-term rate that looks attractive today could underperform a future PTC if wholesale prices drop. Given the current PJM trajectory, that downside scenario looks unlikely. But you are only changing the supply portion of the bill. Distribution charges stay with DLC.

Enroll in the Expanded Time of Use Program

For households that can shift load to off-peak hours, especially those with EVs, electric water heaters, or flexible appliance schedules, TOU can produce real savings against the standard PTC. The program is voluntary and requires a smart meter (which most DLC residential customers now have). DLC’s website includes a TOU rate calculator that helps customers estimate potential savings based on actual usage patterns.

Apply for Customer Assistance Programs

DLC participates in Pennsylvania’s standard universal service programs: the Customer Assistance Program (CAP), LIHEAP for federal heating assistance, the Smart Comfort LIURP for low-income weatherization, and the Hardship Fund. The 2024 settlement expanded auto-enrollment using LIHEAP data and added shareholder-funded contributions to the Hardship Fund through 2027. These programs do not change the rate; they change what qualifying customers pay.

Generate Your Own Electricity with Solar

Solar panels let you produce your own electricity at a cost determined the day your system is installed. Unlike shopping for a supplier or shifting usage, solar fundamentally restructures your relationship with the utility.

For a typical residential solar installation in DLC territory, the levelized cost of solar over a 25-year system life runs well below the current DLC all-in rate of 23.1 cents per kWh, and that cost does not rise with PJM auction results, distribution rate cases, natural gas markets, or DQE Holdings infrastructure investment plans.

Pennsylvania’s solar policy environment supports this through two key mechanisms:

• Net metering at retail rate: Excess energy sent to the grid is credited at the full retail electricity rate, not a lower wholesale rate
• Solar Renewable Energy Credits (SRECs): Pennsylvania homeowners earn one SREC per megawatt-hour of solar production, currently selling for roughly $25 to $40 per credit on the open market

For DLC customers specifically, the math is more compelling than for any other major PA utility. At 23.1 cents per kWh, the avoided-cost value of every kWh produced by a residential solar system is the highest of any PA utility, and the spread between solar production cost and grid electricity cost is the widest. Every cent added to DLC’s all-in rate compresses solar payback further, and the rate has been moving in only one direction.

Are Duquesne Light Rates Going to Keep Rising?

The structural factors driving DLC rate increases are not short-term disruptions.

• PJM’s demand forecast for the 2027/2028 delivery year increased 5,250 MW year-over-year, with nearly 5,100 MW attributable to data centers across the 13-state PJM region
• The July 2026 PJM capacity auction will not include the Shapiro-negotiated price cap, which is likely to push uncapped capacity prices higher (though some observers expect the cap to be reinstated)
• DLC’s stay-out provision expires March 20, 2026, opening the door to a new base distribution rate case filing. Historical pattern across PA utilities suggests filings come close to the earliest allowable date when PJM cost pressure is high
• DLC’s ongoing infrastructure modernization, EV transportation electrification programs, and grid hardening investments will continue feeding into rate base
• The June 2026 PTC reset will reflect the FERC-capped PJM auction results and additional wholesale cost increases

The PTC will continue to fluctuate semi-annually. Distribution rates are stable through at least late 2026, then likely move higher in any new rate case proceeding. For DLC customers, planning around continued elevated rates is more realistic than planning for a return to pre-2024 levels.
