803: Virtual Transmission - The Missing Link to Zero-Emissions Electric Grids
Date & Time

Description

For many years, electricity networks have faced the dual challenges of needing additional power flow capacity on transmission lines at specific areas of the grid and managing excess transmission capacity at areas that required less energy. This imbalance ultimately led to network congestion and underutilization, which increased costs for both the provider and the consumer.  The rise of renewable energy generation has created new demand and bottlenecks on transmission systems designed for less variable, legacy generation assets. As a result, transmission operators are increasingly interested in low-risk, yet scalable, alternatives to the conventional method of energy transmission through traditional power lines. Battery-based energy storage as a transmission enhancing asset is a cost-effective and sustainable solution for networks to maintain reliable and affordable energy on the modern grid.  Deploying storage as “virtual transmission” involves the placement of an energy storage asset along the transmission line at strategic points to inject or absorb power and mimic the transmission line flow. While this method is a fairly new approach to alleviating power line congestion and underutilization, network operators around the world are adding, or planning to add, hundreds of megawatts of capacity.  Compared to traditional transmission resources, virtual transmission provides myriad benefits. It can be flexibly located as needed—without environmentally or socially invasive construction—and can dramatically reduce the time to plan, permit and deploy transmission infrastructure. In addition, virtual transmission provides reactive power solutions to preserve system performance during temporary transmission outages or prevent blackouts, while significantly lowering network owners’ infrastructure investment costs. In this session, you’ll learn how storage as transmission will play a critical role in developing the future of the energy grid, helping provide a sustainable and reliable path in power generation for years to come.
