Accenture and OGE Energy Corp., the parent company of Oklahoma Gas & Electric (OG&E), Oklahoma’s largest electricity provider, said a seven-year smart-grid program contributed to demand reduction targets by automating control devices using digital technology.
The Integrated Volt Var program is part of OG&E’s strategy to drive efficiencies and customer savings that have helped defer investments in power plant capacity.
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.
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.
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.
