Editor’s Note: Rising utility costs have become a hot topic at both the conference table and the kitchen table over the past year. The issue highlights a conflict between the desire for affordable energy and the hard reality of how markets and power grids actually work. Wholesale commodity markets, driven by fluctuating natural gas prices and extreme weather, were the primary culprit in the most recent round of sticker shock last month. Those impacts will linger for at least another month or two. However, the broader impacts of capacity shortages in PJM and MISO, and various ancillary programs in NEISO will be much longer lived.
It’s time to review the basic components of a kWh and then work to dissect this complex landscape, analyzing why a ratepayer in California pays nearly triple the per-kWh rate of one in Louisiana, and then highlighting other trends that influence why costs shift and what you can do about it as a consumer. From capacity market reforms to contentious rate cases, there are many moving pieces we’re following in 2026.

Understanding your electricity bill has never been more critical. While the national average retail rate rose about 4¢/kWh from 2020-2025, some regions saw increases three times higher, highlighting stark geographic differences. This article examines how supply costs (generation and commodity) and delivery costs (transmission and distribution) combine differently across major U.S. markets. In the Northeast, rising wholesale and capacity prices drove supply-side volatility; in California, delivery-side costs such as wildfire mitigation and grid hardening led the surge. Most of these increases are pass-through operating costs and the increases have not meaningfully enhanced utility earnings. Without improved earnings, utilities lack capital for the infrastructure investments that could address the root causes of these rising costs.
When you open your electricity bill, you're looking at the end result of a complex chain of costs that vary dramatically by region and market structure. At its core, your electricity bill consists of two major components:
1. Supply Costs (Commodity): The cost of generating or purchasing the electricity itself. This cost includes various components such as energy, capacity, renewable portfolio standard charges and cost-to-serve charges.
2. Delivery Costs (Transmission & Distribution): The cost of maintaining poles, transformers, wires, and infrastructure to deliver power to your home. This includes various components such as distribution, transmission and other miscellaneous charges.
The article below includes stack charts for several major markets that illustrate the key retail rate components paid by end-use commercial customers in 2025.
The relative impact of these components varies dramatically by region and market structure. In deregulated electricity markets (PJM, ISO-NE, CAISO, etc.), where utilities don't own generation assets, supply costs are directly tied to wholesale market prices. In traditional vertically-integrated markets (ie: Pacific Northwest, Mountain West, and Southeast US), utilities own their generation and recover costs through regulated rates.
Based on a recent analysis done by CRA, national average electricity retail rates from the 2020-2025 period for primarily residential customers have remained relatively stable, increasing only by 4¢/kWh, while a subset of states have experienced increases three times larger, driven primarily by their respective operational factors, as depicted in the graphic below.
The various factors impacting these larger rate increases in markets, such as the Northeast and CAISO, are covered in the section below.
The Northeast: A Case Study in Wholesale Market Exposure
The Northeast region, particularly states within ISO New England and PJM, has experienced the most dramatic supply-side-driven rate increases. For example: Since 2020, retail rates in Massachusetts have increased by up to 8.4 ¢/kWh, however due to the volatility of supply costs as compared to delivery costs, that change has been both positive and negative year-over-year .
The primary culprit is surging wholesale electricity market prices. In deregulated markets like ISONE, NYISO, and PJM, utilities that don't own generation must purchase power from wholesale markets. When wholesale prices spike, these costs flow directly through to retail customers, increasing the costs for energy, capacity, and ancillary services (A/S), etc. as shown in the chart below.
PJM Interconnection: Capacity Market Pressures
In the PJM region, supply-side costs have been driven by factors beyond energy prices. The capacity market, which ensures adequate generation resources are available to meet future demand, has added high costs:

California: A Delivery-Side Story
California (CAISO) has also experienced rate increases of 12¢/kWh over the last five years driven by factors beyond wholesale market volatility. The rate increases stem primarily from delivery-side (ie: distribution) costs rather than supply-side volatility, demonstrating how regional factors create vastly different bill impacts. Some of the factors that contributed to the delivery-side cost increases are: wildfire mitigation investments and state’s rooftop solar compensation structure.

Understanding the anatomy of your bill and the factors driving each component is essential to anticipating future cost trends. Recent increases largely reflect supply- and delivery-side volatility and consist primarily of operational expenses recovered on a pass-through basis, without adding to utility earnings. Without improved earnings, utilities lack capital for the infrastructure investments that could address the root causes of these rising costs. In effect, these rate increases cover only immediate operational costs without funding the capital investments needed to address the underlying “principal” of rising electricity cost pressures.
Given these dynamics, the affordability solutions must be region-specific. Policymakers should focus on the distinct cost drivers within their jurisdictions rather than applying broad national remedies, ensuring that strategies target the underlying sources of rate pressure rather than the symptoms.
A recent shift in New England's energy market, designed to bolster grid reliability, has had an unexpected side effect: unprecedented cost volatility. Ancillary service charges, once a minor line item, have soared far beyond projections, and these costs are now appearing on consumer bills—even for those with fixed-price contracts. Our latest analysis unpacks the billion-dollar consequences of the new Day-Ahead Ancillary Services Initiative (DASI) and explores the urgent fixes being proposed to restore stability.
Effective March 1, 2025, ISO New England launched the Day-Ahead Ancillary Services Initiative (DASI), overhauling how the grid procures essential reliability services. Replacing the Forward Reserve Market, DASI now prices and procures Flexible Response Services (FRS) and Energy Imbalance Reserves (EIR) 1 day in advance - elevating resource flexibility to a premium product. This shift aims to modernize the grid and enhance reliability by financially rewarding power generators for greater flexibility and responsiveness to real-time system needs. We previously covered DASI in an earlier newsletter.
Ancillary services are critical for maintaining grid stability, balancing supply and demand, stabilizing frequency, and ensuring reserves during disruptions. Under the previous system, these services were purchased months ahead at flat rates. DASI’s day-ahead procurement better aligns supply with actual grid conditions, especially as intermittent renewable energy. While it improves operational accuracy and incentivizes flexibility, it makes costs highly sensitive to daily market fluctuations like natural gas prices, generator outages, and extreme weather. This new approach has led to an unintended consequence: a dramatic and volatile increase in costs.
Ancillary services have historically been a small share of wholesale electricity costs, but DASI has driven expenses far beyond expectations. ISO-NE initially projected $135 million annually, but by January 2026, program’s cumulative costs reached approximately $1.15 billion. The chart below shows the weekly cost for various DASI components (excluding the “Closeout Charge Dollars” component) and cumulative cost since its inception.

The weekly DASI rates have swung dramatically from $0.56/MWh to $122/MWh, compared with historical costs near $1.50/MWh, and closely track day-ahead LMP price volatility as shown in the chart below. Events like Winter Storm Fern had amplified effects where the settled monthly January rate was ~$40/mWh, significantly higher than any prior monthly rates.

The financial impact of these escalating DASI costs is now being felt by retail energy consumers. Most electricity supply contracts allow these ancillary charges to be passed through, leading to higher, unpredictable bills. Even customers with fixed-price agreements are not immune, as suppliers use "Change in Law" provisions and other adjustments to recoup these unforeseen expenses.
In response to the significant financial burden on consumers, the grid's Internal Market Monitor has proposed three urgent adjustments to the DASI market. These adjustments aim to lower costs while maintaining reliability and improving market efficiency.
While a final decision from ISO-NE on moderating DASI costs is expected before year-end, market volatility will persist. Veolia stands ready to navigate these changes, arming you with market insights, contract guidance, and proactive risk strategies needed to stay informed, prepared, and protected.
In a previous newsletter we covered the record-setting PJM capacity auction and subsequent FERC order requiring new rules for data center interconnection. This past month, federal and state representatives have directed PJM to take immediate action to address consistent capacity shortfalls that are negatively impacting ratepayers. Members of the National Energy Dominance Council (NEDC) and governors in PJM issued a statement outlining the tariff changes PJM must implement to properly manage large-load interconnection. A day later, the PJM Board issued its own letter outlining similar demands. Here are the key takeaways:

If the current BRA price collar is extended as planned, it all but guarantees capacity prices above $300/MW-day through 2030. Until further notice, ratepayers in PJM will feel the cost impacts of a grid that’s straining to keep up with capacity demands. If you’re looking for a silver lining, PJM’s price collar mechanism has helped reduce capacity costs by over $13 billion over the past three years. The 2027/28 auction would have cleared at over $500/MW-day without it, according to PJM, with subsequent years likely to follow suit. See the chart below outlining the historical clearing prices and projections for the next two years.

Extending the price collar is just the first step in what will prove to be a pivotal year for PJM’s capacity market. The bigger picture is that an overhaul of this market has become increasingly necessary as an unprecedented number of large loads interconnect to the grid. The proposed solutions are more dynamic, allowing large loads that generate their own power to jump to the front of the queue, while establishing strict rules for curtailing loads that don’t generate their own power. There are several remaining uncertainties, but the blueprint given to PJM shows some promise of shoring up capacity while simultaneously protecting ratepayers. We’ll be watching closely to see how this story develops.
