Kiewit announced as the EPC, IHI Terrasum Solutions as the integrator for the 690 MWac PV/1416 MWh BESS Project

OAKLAND, Calif – March 3, 2022Primergy Solar LLC (‘Primergy’), a leading developer, owner and operator of utility and distributed scale solar and storage, announced today the final selection of major equipment suppliers and construction partners for the highly anticipated $1.2 billion Gemini Project located near Las Vegas, Nevada. Primergy is a portfolio company of Quinbrook Infrastructure Partners (‘Quinbrook’).

After a comprehensive and detailed procurement process, Primergy selected Kiewit Power Constructors Co. (Kiewit) as Gemini’s engineering, procurement and construction (EPC) partner and IHI Terrasun Solutions (Terrasun) as the battery storage integrator. Both companies have decades of experience in construction and installation, product development, procurement and systems integration in the renewable energy and power sector. Maxeon Solar Technologies was also selected to provide its high efficiency bifacial solar modules.

“The final selection of equipment supply and construction partners for Gemini has been a long, detailed and thoughtful process. The Quinbrook and Primergy teams have worked diligently to evaluate each supplier’s credentials and track record from an ESG perspective in accordance with Quinbrook policies. This includes detailed supply chain investigation and materials sourcing to ensure we have procured responsibly, especially in a challenging market and regulatory environment for solar and storage equipment. We believe we have chosen the best possible technical combinations for a milestone project and applaud our respective teams for their efforts to get to this point.’

Co-founder and Managing Partner

The unprecedented Gemini project is a $1.2 billion, 690 MWac/966 MWdc solar array and 1,416 MWh storage facility that will deliver power when Nevadans need it most. The project will feature over 1.8 million solar modules installed on approximately 6,500 acres of federal land and will produce enough clean energy to power the entire city of Las Vegas. During the construction phase, Gemini is expected to create approximately 1,000 local jobs, which will be sourced through union participation. Construction is expected to be completed in 2023 with operations beginning shortly thereafter.

The Gemini Project is extraordinary in its scope and scale, and we are excited to join Primergy
in significantly expanding the availability of clean energy,” said Dave Flickinger, Executive Vice
President of Kiewit Energy Group, Inc. “With more than 40 years of experience in developing
renewable energy projects, we are well equipped to deliver an outstanding solar array and battery
system while also supporting Primergy’s commitment to safety, reliability, environmental
stewardship and the surrounding community.

IHI Terrasun is proud to be part of such a historic moment,” said Jamal Burki, President of IHI
Terrasun. “We look forward to bringing our advanced DC-coupled solar and storage solutions to
the Gemini Project while employing our lifecycle services aimed at ensuring a smooth and
reliable operations for all involved.”

Primergy has invested significant resources to minimize the physical footprint of the Gemini
project where practicable to both preserve and protect local flora and fauna. The company has
partnered with biologists to create the industry’s first Desert Tortoise Relocation Plan, which
tracks, cares for and will safely reintroduce the protected species back into their natural habitat
once construction is complete. Additionally, Primergy will implement responsible and efficient
construction processes, such as using alternative site preparation methods, establishing narrow
road corridors into the project site, and building appropriately spaced, raised rows of solar
modules to ensure nearly 80 percent of the land on site remains open to the sky.

While the size, scale and innovative integration of solar PV coupled with battery storage makes
Gemini one of the most complex clean energy projects ever developed, Gemini also sets new and
timely benchmarks in sustainable infrastructure development,” explained Ty Daul, CEO of
Primergy. “Through Gemini, Primergy has pioneered a holistic approach to responsible project
development that considers complete ecosystem management, collaborative partnerships with
local and community stakeholders and undertakes careful due diligence in supply chain and
equipment selection. This ensures the company procures responsibly, minimizes environmental
impact and delivers lasting community benefits across jobs, training and ongoing education in
the benefits of large-scale clean energy infrastructure.

Primergy’s Nevada portfolio alone exceeds 1,300 MWac of solar and 3,330 MWh of battery
energy storage systems (BESS) under contract with NV Energy as well as multiple additional
projects in the development phase. Established in 2020, Primergy has quickly established a
leadership position in large scale solar and storage projects with a growing platform now
exceeding 6 GW of both operational and development assets across the US.
