The Nebraska Environmental Trust (NET) formally approved the $600,000 grant to OPPD on June 11.
The grant will help fund the OPPD Battery Storage Pilot, which will provide research and direct benefits for the utility.
NET is funded by Nebraska Lottery proceeds. It has awarded more than $320 million in conservation projects in the state since 1994. The grant approval included matching funds from OPPD for the pilot project.
“This is a very big deal and the grant helps us accelerate our utility scale storage efforts,” said Michal Lisowyj, alternative energy specialist at OPPD.
Lisowyj said OPPD will use the stand-alone battery for grid support. It will be housed in a substation.
“We want to understand how various use cases and recurring cycling degrades the battery, much like a cell phone battery that doesn’t hold the same charge over time,” Lisowyj said. “This will provide learning for potential future energy storage projects. I know there is a lot of interest around energy storage at OPPD and this will allow us to see what it can do. We want to learn as much as we can from this experience.”
The battery will likely be approximately 1 megawatt in size, small enough to fit in a storage container. The grant enables the utility to perform research that will benefit not only OPPD, but other utilities in Nebraska
The pilot program will test how battery storage can integrate into OPPD’s grid, providing load relief and voltage support at the substation level. The research gleaned in the pilot will help the utility understand the procurement, construction and operations of small energy-storage applications and how to scale for potential future applications.
“This is the largest grant we’ve received from NET,” said Karisa Vlasek, OPPD’s coordinator for Grants & Stakeholder Outreach. “There is a lot of excitement around this.”
Last summer, OPPD announced a strategic initiative to study pathways to decarbonization. The study includes emerging technologies such as battery storage. The battery project is slated to be operational by December 2021.
