210,600-square-foot facility completes construction; joint venture targets 2 GWh initial capacity, scalable to 8 GWh.
NeoVolta’s battery energy storage system manufacturing facility in Pendergrass, Georgia, has completed construction and is advancing through commissioning and production ramp-up activities as the plant moves toward commercial operations.
The 210,600-square-foot facility, owned by joint venture NeoVolta Power LLC, is progressing through site acceptance testing and certification for its initial production line, with the production ramp expected to begin in the second quarter of fiscal 2027.
Facility status and timeline
The Pendergrass facility has completed construction and entered the final validation phase ahead of repeatable manufacturing. The initial production line is progressing through commissioning and site acceptance testing, with quality and certification processes being finalized ahead of the production ramp.
The facility is designed for an initial annual production capacity of 2 gigawatt-hours (GWh), with the potential to scale toward 8 GWh as additional production lines are added within the building.
Partners and ownership
NeoVolta Power LLC operates the Pendergrass facility as a joint venture involving NeoVolta, PotisEdge and LONGi Green Energy. NeoVolta initially held a 60% controlling interest and now owns 80% of the venture as of fiscal year-end 2026.
PotisEdge brings BESS manufacturing and commissioning capabilities, while LONGi Green Energy participates through its broader solar and energy-storage platform. NeoVolta leads product strategy, customer engagement and operational control.
Commercial commitments and supply agreements
The production ramp follows a binding capacity reservation agreement with Infinite Grid Capital to provide BESS for Northern Ontario Edge AI data center projects in calendar 2027. The agreement carries an approximate $53 million value and follows an earlier non-binding letter of intent covering approximately 1.1 GWh of potential utility-scale deployments valued at about $200 million.
On August 31, 2026, NeoVolta Power announced a five-year strategic supply and manufacturing collaboration with SK On. Under the agreement, SK On will supply NeoVolta Power with 9 GWh of U.S.-manufactured lithium iron phosphate (LFP) cells from 2027 through 2031. The companies also established a framework for an additional 9 GWh of LFP cell supply and for SK On to purchase energy storage packs that NeoVolta Power manufactures. Together, the signed agreement and broader framework could support up to 18 GWh of combined activity between the companies.
Project financing and capital
To support working capital for the production ramp and investment in a second production line, NeoVolta entered into a senior secured term loan facility providing $20 million, less a $1 million original issue discount, with the potential to increase the aggregate commitment by up to an additional $10 million by mutual agreement with the participating lenders.
The financing follows NeoVolta’s May 2026 public offering, which strengthened the company’s balance sheet ahead of the manufacturing ramp.
The Pendergrass facility has received a formal opinion confirming Foreign Entity of Concern (FEOC) compliance for the facility, the NVApex 5MWh BESS and NeoVolta’s NVWave residential product, positioning them for eligibility under Inflation Reduction Act Section 48E tax credits.
“Fiscal 2026 was defined by the progress we made at Pendergrass,” Chief Executive Ardes Johnson said. “Our facility is advancing through commissioning and production-ramp activities, and our strategic collaboration with SK On supports our long-term capacity-expansion plans through a multi-year U.S.-manufactured LFP cell-supply agreement and broader pack-manufacturing collaboration.”
Chief Financial Officer Jing Nealis said the company will focus on “disciplined execution of the Pendergrass production ramp and converting commercial opportunities into durable growth” in fiscal 2027.
The Pendergrass ramp-up comes as other U.S. energy projects expand domestic manufacturing capacity across emerging power technologies, including TRISO-X’s advanced nuclear fuel facility in Oak Ridge, Tennessee, which recently completed its main structure.
What comes next
Over the coming quarters, NeoVolta Power plans to complete site acceptance testing, convert its utility-scale and C&I pipeline into binding orders, and advance a second production line that could scale the Pendergrass site toward 8 GWh of annual BESS production capacity in calendar 2028.
