As we look ahead to 2025, the electricity landscape in New England is undergoing significant changes. ISO New England (ISO-NE) is implementing new regulations and phasing out existing programs that have been central to the region's energy market. These shifts aim to improve grid reliability and encourage cleaner energy sources, but they come with cost implications that can directly affect the non-energy components—or index adders—of contracted rates.
This means that even if physical energy markets are declining, these added costs can counter the expectation that "markets are down, so I’ll get a better rate." If you're looking to fix prices, it's important to time that purchase when physical prices are down to offset the impact of these increasing non-energy cost components.
ISO New England's 2025 Changes: What They Mean for Your Energy Costs
Key shifts include the end of the Inventoried Energy Program (IEP), the launch of the Day-Ahead Ancillary Services Initiative (DASI), and updates to Massachusetts' Clean Peak Standard (CPS). While these changes aim to strengthen the grid and promote clean energy, they can also contribute to higher overall rates for consumers—despite lower commodity prices. Here’s a closer look at each change, its purpose, and its potential impact on costs:

End of the Inventoried Energy Program (IEP)
What is it? The IEP was designed to enhance winter reliability by providing payments to generators for maintaining fuel reserves, such as oil or liquefied natural gas (LNG). This program helped ensure fuel availability during cold snaps when demand peaks.
Impact on costs: While the expiration of the IEP in February 2025 may reduce costs associated with fuel security in the region, the risk of fuel shortages will shift back to generators. This shift could lead to added market volatility due to more conservative bidding behavior by generator owners, especially if they base their offer curves on replacement fuel costs—which could be much higher if they lack sufficient on-site fuel to meet demand.
Day-Ahead Ancillary Services Initiative (DASI)
What is it? DASI is a new program that will replace the Ancillary Services Forward Reserve Market on March 1, 2025. It is designed to bolster grid reliability by securing energy reserves a day in advance, ensuring that extra power is available if demand spikes unexpectedly or if supply falls short.
Impact on costs: The costs associated with maintaining these reserves will be passed on to end users, increasing non-energy charges. Suppliers will incorporate these new costs into future contracts, resulting in higher overall expenses for end users. However, DASI is expected to deliver improved reliability and reduced volatility across the ISO-NE grid. Balancing these additional costs with the benefits of enhanced grid stability is vital for effectively managing overall energy expenses.
Updates to Massachusetts’ Clean Peak Standard (CPS)
Source: ISO New England
What is it? The CPS incentivizes the use of renewable energy during peak demand periods when the grid is under the most stress, requiring electricity providers to source a portion of their energy from clean sources during these times.
Impact on costs: The stricter CPS requirements starting in 2026 will increase costs for suppliers, who may need to invest more in renewables and storage to meet the standards. Additionally, the increase in the Alternative Compliance Payment (ACP) to $65/MWh sets a higher price ceiling for Clean Peak Energy Certificates (CPECs) needed to prove compliance. These costs incurred by suppliers will likely be passed on to end users, increasing the overall expense of complying with clean peak standards.
Why Fixed Rates May Rise Despite Lower Commodity Prices
Even as commodity prices fall, non-energy components tied to new regulatory programs can lead to increased costs, directly impacting contracted rates. End users should be mindful of these changes when considering their energy strategies. By staying informed and considering strategies like long-term contracts or energy efficiency investments, businesses can manage the potential impact of these adjustments on their budgets. In an evolving energy landscape, being proactive can make a significant difference in navigating these shifts.
