Oklahoma Gas and Electric (OG&E) is Oklahoma's largest electric company, serving more than 907,000 customers in Oklahoma and western Arkansas. The utility is anticipating the rapid adoption of flexible energy storage across its grid – but is faced with the challenge of going “from zero to 60” with this technology.  OG&E recognized the need to comprehensively qualify mobile and stationary battery energy storage by conducting first-hand evaluation of the technical, financial, and operational viability of the technology.

OG&E accomplished this feat by breaking ground and installing a flexible utility-scale battery energy storage system (BESS) at their distribution testing facility. The 500 kW / 664 kWh BESS pilot allowed OG&E to rapidly narrow their knowledge gap, develop planning, deployment, and operations standards. OG&E robustly tested a variety of applications and use cases such as:

  • Grid enhancement and stabilization methods

  • Voltage regulation

  • Capacity firming
  • Microgrid operation
  • Electric vehicle (EV) fast charging peak load mitigation

The results and outcomes of the testing enabled OG&E to effectively qualify BESS vs. other solutions and provided a basis to confidently plan for the deployment of much larger BESSs in their territory.

This interactive presentation will give Distributech attendees an opportunity to learn about OG&E and TRC’s collaboration, and the process that lead to the successful pilot. The speakers from OG&E and TRC will discuss their experience, lessons learned, and outcomes, including:

  • Pilot planning, conceptualization, and engineering

  •  

    Determining the right pilot size to serve as meaningful proof of concept (and stay within budget)

     

  • BESS supplier evaluation and selection

  • BESS codes and standards compliance

  • Fire safety preparedness

    Site installation and civil works

  • Interdepartmental collaboration – Grid Innovation, Distribution Planning (EV, DER), Procurement, etc.

  • OG&E workforce training

  • Test cases and results

  • Assessing the costs and benefits of battery energy storage vs. other solutions

  • Use cases recommendations

  • Mobile energy storage deployment strategies

  • Scaling beyond pilot size for field deployment

  •  

    Standards development for integration of utility as well as third-party BESS projects
