USA, New York: A new report from the Columbia University Center on Global Energy Policy outlines how grid operators can unlock more capacity from existing transmission networks without constructing new power lines.
The study focuses on grid-enhancing technologies (GETs), which can increase efficiency, reduce congestion and lower costs. These tools allow operators to make better use of current infrastructure, helping meet rising electricity demand driven by electrification and data centres.
Instead of relying only on large, expensive transmission projects, the report highlights solutions such as dynamic line ratings and advanced power flow controls. These approaches can be deployed more quickly and at a lower cost, offering a practical way to improve grid performance in the near term.
The authors note that while expanding transmission remains essential, it often faces delays due to permitting and regulatory hurdles. In contrast, GETs can provide immediate relief by optimising how electricity flows across existing networks.
However, the report also points out that adoption has been slow. Regulatory frameworks and market structures have not always supported widespread deployment, limiting the impact of these technologies so far.
The study calls for policy changes to encourage greater use of GETs, arguing that they can play a key role in improving reliability, cutting costs and supporting the integration of renewable energy.
As electricity demand continues to grow, the report suggests that making smarter use of existing grids could be one of the fastest and most cost-effective ways to strengthen energy systems.
