VPPs, other advanced technologies could each expand existing US grid capacity 20-100 GW: DOE

AI generated summary

The Department of Energy in the United States has highlighted the potential of deploying advanced grid technologies on existing transmission and distribution systems. According to a new DOE report, these technologies could support up to 100 GW of additional peak demand when implemented individually, with even greater capacity when used in combination. The deployment of technologies like dynamic line ratings (DLR) and virtual power plants could potentially save billions of dollars in infrastructure costs over the next five years, and they can be implemented at a fraction of the cost and in significantly less time compared to traditional transmission projects.

The report assesses 20 advanced grid solutions, including various technologies such as advanced conductors, distribution management systems, and communications technologies. The DOE emphasizes that while these advanced grid technologies offer benefits such as increased capacity, improved reliability, and cost reduction, their widespread adoption is still limited due to existing utility business models. The report suggests that achieving commercial liftoff for these solutions will require comprehensive valuation and integration of these technologies by utilities and regulators into their grid planning, operations, and investments.
