Facilitate Large-Scale Renewable Integration

Facilitate Large-Scale Renewable Integration


Public policy goals are increasingly shifting the electricity sector toward low-carbon generation sources to reduce greenhouse gases and address global climate change. However, siting and integrating renewable energy resources can be a challenging, lengthy and costly process. Power must be delivered from new regions that are often located far from load centers, while renewable intermittency creates challenges to power flow management.


Recognizing the challenges associated with large-scale renewable integration and the potential benefits of game-changing technologies, Smart Wires commissioned a DNV-GL economic assessment of the changes necessary to PJM’s transmission grid to make it capable of supporting 30% penetration of renewable generation by 2026.

This study shows that considering Smart Wires solutions in conjunction with conventional transmission enhancements like reconductoring or building new lines has the potential to reduce total CAPEX investment by nearly 50%, and eliminate the need to build or reconductor nearly 300 circuit miles. These benefits are achieved while providing equal or better operational performance measured in terms of locational marginal prices, renewable energy deliverability, transmission congestion, and cost.
