Amid growing electricity demand, SPP and Hitachi are set to launch an AI-powered initiative aimed at reducing interconnection delays and improving US energy grid reliability.
Southwest Power Pool (SPP) has partnered with Hitachi to develop a cutting-edge artificial intelligence (AI) solution to solve major delays in the US power grid’s generator interconnection (GI) process.
The joint effort is expected to reduce GI study times by up to 80 per cent, enabling faster integration of new energy sources across SPP’s 14-state region. The first phase of the project is expected to conclude by winter 2025/26. The primary outcomes include system acceleration, improved data management, and AI-enhanced simulation tools.
The initiative leverages Hitachi’s suite of AI technologies, built on NVIDIA’s accelerated computing platform. According to the company, core elements include AI-powered power simulation, predictive analytics, and advanced data modelling.
Together, these tools aim to streamline grid planning, enhance reliability, and strengthen emergency response efforts.
Electricity demand in the US is rising rapidly, driven by data centre expansion, growing manufacturing, and increased electrification. Without timely upgrades, capacity margins in the SPP region could drop from 24 per cent in 2020 to just 5 per cent by 2029.
SPP stated that a major issue lies in the interconnection backlog, with over 2.5 terawatts of potential generation stuck in the queue due to lengthy studies required to ensure grid stability. The new AI solution is designed to automate and accelerate these processes, unlocking access to urgently needed energy capacity.
The partnership draws on expertise from multiple Hitachi units, including Hitachi Energy, GlobalLogic, and Hitachi Vantara. It will also use the Hitachi iQ platform to deliver real-time insights and AI-driven decision support.
SPP will oversee project integration, aligning the technology with existing regulatory frameworks and operational standards.
“Our grid is being tested by rapid demand growth and outdated systems,” said Marie Caldwell, Vice President of Grid Innovation at SPP. “This partnership is about more than faster studies—it is about reshaping how we prepare the grid for the future. With AI at the core, we are building a smarter, faster, and more flexible power network.”
