The US Department of Energy has published its Transmission Interconnection Roadmap, setting an aggressive success target for interconnection improvement by 2030 and outlining tools to improve the process for connecting more clean energy projects to a reliable grid. The roadmap was developed by the US DOE’s Interconnection Innovation e-Xchange (i2X) program. It provides a broad range of players such as transmission providers, state agencies, federal regulators, equipment manufacturers, and other actors with a set of 35 solutions to ensure all stakeholders have better access to data and improved standards and procedures while developing and maintaining a more efficient, reliable, and clean grid. The roadmap includes four target metrics for interconnection reform including shorter interconnection times, lower interconnection cost variance, increased completion rates, and zero disturbance events attributed to modelling.
According to the DOE’s Lawrence Berkeley National Laboratory, the generation and storage capacity actively seeking grid interconnection has dramatically increased to nearly 2,600 GW, representing an eight-fold increase since 2014. The US DOE’s i2X program was launched in 2022 to enable simpler, faster, and fairer interconnection of clean energy resources while enhancing the reliability, resilience, and security of the electric grid. The US aims to achieve 100% clean electricity by 2035.
