Lineage Sues Altus Power and a CBRE Contractor for More Than $1 Billion Over Rooftop Solar Fire

Cold-storage operator Lineage, Inc. has filed suit in Los Angeles County Superior Court seeking more than $1 billion over the June 17 fire that destroyed its 500,000-square-foot temperature-controlled logistics facility in Boyle Heights, Los Angeles. The defendants are Altus Power, Inc., its project subsidiary Los Palos Street Operating, LLC, and Pearce Services LLC, a maintenance contractor that is a subsidiary of CBRE.

The ownership structure. Lineage did not own the array on its roof. Altus owned the system through its project subsidiary, and Pearce performed maintenance under contract to Altus rather than to the building owner. The cold-storage operator supplied the roof and ran the operation underneath it. That is the standard shape of a third-party-owned energy asset on a commercial building, and it is now being tested for something other than tax-equity efficiency.

The allegations. The complaint counts negligence, negligent supervision, breach of contract and violations of the state health and safety code. The central allegation is a control failure rather than an equipment failure: Lineage says it issued written instructions that the system remain de-energized until voltage checks and a review of duplicate device serial numbers were complete, and that the defendants began re-energizing the array on June 5 regardless.

A smaller fire had already occurred in the same rooftop array in August 2024. Altus retained Pearce to reconfigure the system after that incident.

None of the allegations has been tested in court, and no cause has been publicly assigned by a fire investigator. What is not contingent on the outcome is the distribution of loss. Lineage lost the facility and the operation inside it regardless of who is eventually found at fault, and recovers only through litigation that will take years. Third-party ownership moved the capital cost and the technical responsibility for the array off the building owner’s balance sheet. It did not move the building.

The handover interval. At a battery asset management session held the same week, operators described the period immediately following construction as the least proven stretch of an energy asset’s life. Christian Lopez, senior director of engineering at AES, described a first-twelve-months equipment availability factor that starts at 88 to 90 percent and trends upward to 95 to 98 percent. Grayson Zwingelberg of RWE pointed to the gap between EPC demobilization and actual revenue as the underexamined interval in the handover. The recurring failure areas named were metering validation, protection and controls, power system modeling and grid compliance. Rohit Patil of New Leaf Energy argued that operations teams belong in the room at roughly 60 percent design completion.

Those figures describe utility-scale batteries rather than rooftop solar, and the two asset classes fail in different ways. The structural observation carries across: the least reliable window in an energy asset’s life is the one after a contractor finishes work and before performance has been demonstrated in service. The Lineage complaint locates its fire inside that window, on a system that had been reconfigured following a prior incident and was being brought back online.

What an indemnity is worth. A contractual risk transfer is worth the balance sheet standing behind it, and the balance sheets in this sector are not uniform. German storage manufacturer RCT Power, founded in 2015, filed for insolvency in Konstanz on September 17 after losing access to its bank accounts and outstanding receivables. The company carried nearly €61 million (about $69.9 million) in liabilities to other companies as of 2024, the year it posted a net loss following profitable results from 2019 through 2023. Distribution partner Enerix terminated its contract.

Fluence cut fiscal 2026 revenue guidance on September 16 to roughly $2.4 billion, down from a $2.9 billion to $3.1 billion revision issued in August, itself already reduced from an original $3.2 billion to $3.6 billion. Adjusted EBITDA moved from a loss of roughly $10 million to a loss closer to $200 million. The company had planned for 11 units per day during an August to September ramp at its Houston plant; August output averaged about three units per day on a corrected figure. Roughly 80 percent of the $600 million revenue reduction traces to US production, including $450 million of delay and about $65 million of penalties largely for late delivery.

Neither company is party to the Lineage suit, and neither is alleged to have any connection to the fire. They illustrate the arithmetic a building owner faces when the entity holding the indemnity is a hardware vendor or a service contractor rather than a large balance sheet. A promise from a counterparty with €61 million of trade liabilities and no access to its own bank accounts is a document, not a recovery.

The procurement consequence. The likely near-term effect, and this is interpretation rather than anything either party has announced, is that commercial property owners and their insurers begin writing into energy asset agreements what they previously handled as pre-signature diligence: named insured status, third-party commissioning records, documented contractor supervision, and an explicit energization protocol specifying who may re-energize equipment attached to an occupied building and on whose written authorization. Vendors holding complete test and commissioning files will clear those terms. Vendors who assemble documentation on request will not.

Fire investigators will eventually determine what started this fire. The contract question sits upstream of that finding, and no standard form for a building-attached energy asset currently answers it. Lineage says it put the instruction in writing. According to the complaint, the array came back on.
