Capstone Green Energy Continues Its Success in the EaaS Market with Multiple New Oil and Gas Long-Term Rental Contracts Totaling 2.2 MW

Capstone is Focused on Growing the EaaS Business Rental Fleet to 50 MW, Using a Portion of the Proceeds from the Recent $8.0 Million Underwritten Public Offering

Capstone Green Energy Corporation (NASDAQ: CGRN), a global leader in carbon reduction and on-site resilient green energy solutions, continues to grow in the Energy-as-a-Service (EaaS) market with newly secured orders totaling approximately 2.2 MW from four U.S.-based oil and gas customers.

The new orders include:

• A 1.4 MW long-term rental contract that is to be deployed in early 2023 in Louisiana,
• An additional six C65 microturbines totaling 390kW of rental power in the U.S. shale fields, and
• Another 400kW of power generation to an oil and gas operator on the North Slopes of Alaska at an existing rental location.

“This 2.2 MW rental expansion into the oil and gas market further diversifies the rental fleet’s customer base, now covering all major market verticals: oil and gas, agriculture, hospitality, datacenters as well as commercial and industrial sites. The rental program eases access to Capstone’s premium product, allowing customers to enjoy the benefits of clean, low cost, reliable power where capital is limited or competing for other spends,” said Marc Rouse, Capstone Green Energy’s Sales Director.

“Capstone is seeing strong customer demand across industries for its EaaS long-term rental services, which had 7 MW under contract in March 2021, 26 MW under contract in March 2022, and 34 MW under contract at the end of July,” said Darren Jamison, President and Chief Executive Officer of Capstone Green Energy. “The successful closing of our $8 million underwritten public offering combined with sourcing additional re-rent units allows us to continue to focus on achieving our previously announced next target of a 50 MW rental fleet, including re-rentals.”

The 1.4 MW solution, which features a Capstone Green Energy C800 and C600 Signature Series microturbine will replace an existing rental reciprocating genset and produce clean and reliable electricity using natural gas directly from the pipeline. The power generated by the microturbines will provide 100 percent of the electricity needed to power on-site pumping equipment such as coolers, motors, pumps, and lights, in addition to an on-site office.

The facility operators wanted a modular, reliable, and cost-effective solution to replace their high-maintenance reciprocating genset. The microturbines, which have only one moving part and use no consumables or lubricants, are a low-maintenance solution, which is a key benefit given the site's remote location. Compared to the former gensets, the new microturbine solution will operate with N+1 redundancy and can be easily expanded.

The additional C65 rental contracts will be deployed across various oil and gas sites and be fueled by natural gas directly from the well sites. This allows customers to keep operational costs low by avoiding extra fuel-cleaning equipment and significantly reducing the negative impact on the environment.

"Facing growing pressure to address climate change, oil and gas companies are pledging to prepare for a ‘lower-carbon’ future. For many, that involves investing in new technologies and infrastructure that can support new, greener ways of generating electricity. These are the key areas in which Capstone Green Energy has built its business and where it continues to innovate," concluded Jamison.
