A massive Tesla Megapack project with 1.3 GWh of energy storage capacity is coming online in Arizona – making it one of the largest battery systems.
Salt River Project (SRP) and Plus Power LLC are behind the massive project.
Yesterday, they announced that it is coming online and should provide enough power for 76,000 homes:
Salt River Project (SRP) and Plus Power LLC today celebrated two new grid-charged battery storage systems, Sierra Estrella Energy Storage and Superstition Energy Storage. Together, these facilities will add 340 megawatts (MW) / 1,360 megawatt-hours (MWh) of additional battery storage capacity to SRP''s system – enough to power 76,000 residential homes for a four-hour period. The batteries will absorb excess energy when customer demand is lower and store it for use during times of peak demand.
By being turned on, it automatically became the largest standalone battery system in Arizona and one of the biggest in the US.
Plus Power has been using Tesla Megapacks in many of its energy storage projects, like the one that replaced Hawaii’s last coal power plant.
The Megapack has quickly become the go-to solution for large-scale energy storage projects.
Last quarter, Tesla deployed a record amount of energy storage, 4 GWh, and most of that is believed to be Megapacks.

Tesla Megapack has been selected to power a massive new record-breaking 1,3 GWh battery system from Neoen in Australia.
This project is the second stage of the Collie Battery project, which is named after a town in Western Australia where the project is located.
The first stage consists of 224 Tesla Megapack 2XL units for 219 MW / 877 MWh of capacity.
Today, Neoen announced that it has received a contract for the second stage, which is even going to be bigger. The company wrote in a press release:
Neoen, one of the world''s leading producers of exclusively renewable energy, has been awarded a 300 MW / 4-hour capacity services contract by the Australian Energy Market Operator (AEMO) in a competitive tender initiated by the Western Australian Coordinator of Energy. The service will be delivered by Stage 2 of Collie Battery sized at 341 MW / 1,363 MWh and consisting of 348 Tesla Megapack 2 XL units. The project is located near the town of Collie, on the country of the Wilman people of the Bibbulmun nation, in the Southwest region of Western Australia (WA). It will connect to Western Power''s new Palmer Terminal substation in the South-West Interconnected System (SWIS), a separate network to the one on the eastern coast of Australia.
Neoen confirmed that it has provided “notices to proceed to Tesla and construction contractor UGL.”
The second stage is expected to be operational in Q4 2025 and provide significant grid services to South-West Interconnected System (SWIS) with the ability to charge and discharge 20% of the average demand of the network.
Despite increased competition, Tesla seems to still have strong demand for Megapack.
A 1.3 GWh project represents more than a quarter of Tesla’s new record-breaking quarterly Megapack deployment capacity.
However, that capacity is increasing fast as Tesla recently disclosed having deployed a new line at its Megafactory in Lathrop and it is also building a new Megafactory in China.
Tesla expects its energy storage business to continue to grow significantly and so far, it is delivering on this expectation.
Tesla Megapack deployment reached an all-time high in the first quarter of the year, along with the company’s energy business reaching higher profit margins than ever before.
During Tesla’s Q1 2024 earnings call held last Tuesday, CEO Elon Musk noted that Megapack deployments reached an all-time high, while the company reached a record profit margin of 24.6 percent on its energy business. By comparison, automotive margins in Q1 landed at 18.5 percent.
In addition, the company says it expects this trend to continue, as it predicts energy storage deployments overall to increase at least 75 percent from last year. Deployments also reached record highs in Q1, with Tesla deploying 4.1 GWh total energy storage deployments, as driven by Megapack deliveries.
“The Megapack, in particular, reached an all-time high in Q1, leading to record profitability for the energy business, and that looks likely to continue to increase in the quarters and years ahead,” Musk said during the call. “It will increase—we actually know that it will—significantly faster than the car business, as we expected.”
Tesla Megapacks to help grow 560 MW/2,240MWh battery in Australia
The recent statements come as Tesla continues to ramp Megapack production at its first “Megafactory” in Lathrop, California, and as it’s just beginning construction on a second Megafactory in Shanghai, China. Once they reach volume production, both plants are expected to be able to produce 10,000 Megapacks per year.
“Lathrop is ramping as planned. We have our second GA line allowing us to increase our exit rate from 20 GWh per year at the start of this year to 40 GWh per year by the end of the year,” added Mike Snyder, Tesla’s Senior Megapack Director, during the Q1 2024 call.
“There''s really nothing limiting the ramp. Given the longer sales cycles for these large projects, we typically have order visibility 12 to 24 months prior to ship date, so we''re able to plan the build plan several quarters in advance.”
As Tesla stated during its Q4 2023 earnings call, its energy business is expected to outpace its automotive business this year. The company deployed 15 GWh of batteries in 2023, increasing from just 6.5 GWh in 2022, and Musk has also said that Tesla is expecting triple-digit growth in this area.
Musk also noted last year that the energy business was becoming its highest margin business, with energy and service now contributing over half a billion to the company’s quarterly profit.
