How NRG’s Power Trading & Client Strategy Teams Prepare 

Welcome back to our Load Growth series. In part one, Robert Ott, Vice President of Origination for NRG Business, unpacked the fundamentals of load growth and its reshaping of the energy landscape. As energy demand continues to surge, the industry is confronting complex questions regarding resource adequacy, competitive pricing, and long-term investment.

In this installment, Robert dives into the practical implications of load growth and how energy providers can adapt to a rapidly evolving grid.

Today’s challenges in load growth

To meet unprecedented energy growth, power markets are rationing scarce resources to only the most compelling projects. Building the infrastructure required to support new load, whether through grid upgrades or onsite generation, demands significant time and cost, which becomes more extensive with the scarcity of three critical needed resources: high voltage electrical equipment, gas turbines, and skilled labor.

Transformers are required to step up voltage from power plants to transmission lines and also lower voltage from transmission lines to supply retail loads. Due to the unprecedented growth in our sector, the demand for critical power equipment has outpaced supply capacity and significantly extended lead times.

Generator step-up transformers now have lead times of 110 to 120 weeks, almost twice the time compared to just five years ago. Circuit breakers are seeing similar delays, averaging around 100 weeks for delivery.1 New gas-fired generation also requires combustion turbines with lead times of up to four years.

It’s not just hardware in short supply; limited skilled labor is also emerging as another significant bottleneck.

Waiting for clear signals

While developers and utilities face technical challenges, they’re also navigating an evolving regulatory environment. Policies and rules for how markets will incorporate new large loads remain ambiguous. Due to the scale and potential grid impact of large load projects, like data centers, states and RTOs/ISOs must balance price stability and grid reliability for existing customers while keeping the market attractive for new business.

This lack of clarity complicates project planning. The Texas Legislature has taken an important step in ERCOT by passing Senate Bill 6, which provides new guidance on navigating the large load interconnection process and behind-the-meter arrangements.

Timelines

Despite best efforts to accelerate new power projects, a misalignment is emerging between timelines for data center development and associated infrastructure upgrades. While data center infrastructure can be procured and constructed relatively quickly, new generation projects and grid upgrades require significantly more time to secure equipment, engineer, and construct.

The result is a critical gap: energy users, especially hyperscale data centers, are looking to move much faster than the grid can accommodate. At the same time, AI-related investments have continued to accelerate with a combined annual growth rate of more than 15% from 2024 to 2028.2 Leveraging our power, gas, and development expertise, NRG is moving at full speed to deliver generation solutions aligned with data center development timelines and spending.

Building for the future

While these challenges are real, and in many cases growing, they are not insurmountable. The solution lies in adapting: moving faster, building smarter, and planning further ahead. NRG has a proven track record of identifying projects with a high likelihood of success and strategically directing resources. With deep expertise across power, gas, and infrastructure development, we are uniquely equipped to help meet the demands of accelerating load growth.

NRG recognizes the critical role of gas-fired generation as one of the fastest-to-implement sources of dispatchable, flexible power. Yet in ERCOT and PJM’s current interconnection queues, natural gas generation accounts for just 8% and 5%, respectively. Since 2020, ERCOT has added only 5.6 GW of dispatchable, thermal generation, compared to more than 57 GW of renewables and short-duration storage.³
