Terrasun to Supply Energy Storage and Lifecycle Services to the 1.4 GWh Gemini Project


IHI Terrasun Solutions, Inc. has signed a 25-year agreement with Primergy Solar to bring energy storage system solutions and lifecycle services to the Gemini Project – one of the largest solar and storage efforts in global history. The project, developed by Quinbrook Infrastructure Partners in collaboration with Arevia Power, will be on 7,1000 acres of federally-owned land in Clark County, Nevada. Once built and operational, Gemini is expected to reduce carbon emissions by 1.5 million tons per year. Primergy just announced this project with the following press release:

Primergy Selects Supply and Construction Partners for Highly Anticipated Gemini Project

Kiewit announced as the EPC, IHI Terrasun Solutions as the integrator for the 690 MWac PV/1416 MWh BESS Project. Primergy’s proprietary low-touch development methodologies ensures minimal environmental impacts to local wildlife for one of North America’s largest solar and battery storage projects

OAKLAND, Calif. March 3, 2022 – Primergy 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.

David Scaysbrook, Managing Partner of Quinbrook said, “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.’

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.

As industry leaders in DC-coupled storage solutions, Terrasun will supply system integration and lifecycle services for the 690MW solar photovoltaic array, which is coupled with a 380-megawatt AC battery storage system.

Terrasun’s technology-agnostic approach integrates multiple top-tier batteries, inverter technologies and intelligent system controls into customer offerings to provide solutions for a project’s unique needs. Within the Gemini project, Terrasun’s 25-year lifecycle services and robust system integration will aid in the smooth implementation of the power plant software, along with a strong Parent Guarantee and reliable maintenance for the duration of the project.
