Oklahoma Smart Grid reduces network demand

A seven year smart-grid programme in Oklahoma has helped reduce demand through automating control devices using digital technology, OGE Energy and Accenture have announced. OG&E, Oklahoma's largest electricity provider and a subsidiary of OGE Energy, has implemented the Integrated Volt Var (IVVC) smart-grid programme as part of its strategy to drive efficiencies and customer savings. Savings through the programme have helped defer investments in power plant capacity.

The IVVC project has enabled real-time voltage readings through telemetry from multiple devices including load tap changers, capacitor banks and voltage regulators as well as near real-time voltage readings from customer meters for operational validation. This has provided OG&E personnel in engineering, customer service, and operations insight into system voltage allowing for additional benefits, such as identifying and resolving customer voltage issues and saving customers money by reducing line-losses.

Accenture Consulting provided project management, distribution planning, and evaluation, measurement and verification (EM&V) services for the IVVC project. The Accenture team helped select equipment and circuits, plan circuit changes, and create deployment packages. OG&E and Accenture recently completed the seventh, and final, year of IVVC deployment designed to achieve a two-percent peak voltage reduction and a proportional reduction in peak demand.

OG&E began working with the Structure Group in 2009, and continued to work with Accenture after it acquired Structure in 2015, to help transform the distribution operations with an integrated smart grid solution. The two companies focused on integrating distribution automation, advanced metering, demand response, cyber security and compliance.

“We have worked with Structure, now part of Accenture, over the years to reach this point of ongoing savings for our customers by optimising voltage and reducing demand,” said Cristi Killian, manager of advanced grid operations and planning for OG&E. “In addition, we now have much greater visibility into the everyday operations of our distribution network so that our employees can provide even better customer service as we continue our smart grid journey.”

“OG&E continues to set the standard in creating the smart grid of the future with the IVVC project,” said Mario Marchelli, managing director who leads Accenture’s intelligent grid operations practice in North America. “This project has been very rewarding for everyone involved, and I thank the entire team for the close collaboration by our companies to drive improved grid reliability through automation.”
