Redefining Gas Acquisition Strategies for Utilities Amidst a Growing Demand
In an era of rapidly growing electricity consumption, driven particularly by data centers, utilities are grappling with the complexities of securing enough natural gas to meet the round-the-clock demands of these energy-intensive facilities.
The surge in electricity demand, projected to increase at more than 3% annually through 2026 and U.S. demand growing around 2.5% annually through 2035, is pushing utilities to rely more heavily on natural gas-fired generation to meet flexible, 24/7 loads, especially from data centers and large industrial customers.
However, this increased reliance on natural gas is creating significant challenges for utilities in regions such as the Northeastern states, where limited gas supply during high-demand periods is a significant risk. Factors like fracking bans and pipeline permitting limitations restrict access, leading to the threat of utilities having to burn more expensive fuels or curtail load.
The complexity of securing natural gas is growing, with cost pressure, delivery constraints, and increased reliance on an outdated system. Waiting until the last minute to secure natural gas can lead to price fluctuations, making it crucial for utilities to embrace a structured and long-term natural gas procurement strategy.
In constrained regions like New England, utilities must model energy systems holistically due to limited land for new renewable generation and natural gas pipeline limitations. Defining clear procurement and hedging objectives and using probabilistic modeling can help utilities quantify price and volume risks.
A phased hedging strategy over a three-to-five-year timeframe can be effective, with early focus on locking in certain volumes and later focus on dynamic adaptation. The delivery network for natural gas needs to be planned for, and it's increasingly important to recognize regional pinch points and infrastructure limits.
While data centers are increasingly adopting energy storage systems to manage their rising energy consumption efficiently, integrate renewables, and ensure uninterrupted operations, these systems will not replace the core role of natural gas plants in balancing real-time load needs in the near term.
As the energy system becomes more integrated and complex, co-optimization of gas and power planning is necessary. Utilities are increasingly harnessing distributed energy resources, including virtual power plants, for energy efficiency and demand side management.
In summary, the outlook indicates a continued tight coupling between rising electricity demand from data centers and natural gas supply challenges for utilities at least through the late 2020s. Ignoring complexity in integrated resource planning and co-optimization may lead to unfavorable decisions on infrastructure. Hedging strategies, such as programmatic hedging and dynamic hedging, can significantly lower risk while allowing utilities to take advantage of short-term market opportunities.

- Despite the increasing need for 24/7 energy sources, such as those used by data centers and large industrial customers, the limited supply of natural gas in certain regions presents a significant challenge for utilities, potentially leading to the use of more expensive fuels or load curtailment.
- As data centers continue to adopt energy storage systems to manage their rising energy consumption, ensure uninterrupted operations, and integrate renewables, natural gas plants will still play a crucial role in balancing real-time load needs in the near term, highlighting the importance of a stable natural gas supply for the operations of these facilities.
