Key Capture Energy has closed a US$300 million letter-of-credit facility with Standard Chartered, adding a major source of financial support for battery energy storage projects moving through development in the United States.
The facility will initially focus on KCE projects in the New York Independent System Operator and Midcontinent Independent System Operator markets. Standard Chartered acted as sole provider and arranger, structuring the facility to support projects as they move from development toward construction and operation.
US$300m Facility Supports Portfolio-Level Development
The transaction is not a conventional term loan tied to one operating battery plant. A letter-of-credit facility provides financial backing for obligations that arise throughout the development process.
“This facility will support KCE’s ability to keep advancing projects through the development process, particularly in the NYISO and MISO markets.” — Seungyong Oh, Chief Financial Officer, Key Capture Energy
Letters of Credit Preserve Cash During Development

Battery developers often need to post collateral before a project begins generating revenue. Grid interconnection agreements, procurement commitments, construction contracts and market participation can all require financial security.
When a developer manages a multi-project pipeline, those obligations can consume significant corporate liquidity. A dedicated LC facility allows KCE to meet qualifying requirements while keeping more cash available for development activity and equity commitments.
That structure becomes increasingly valuable as projects move through different stages at the same time. One battery may be negotiating interconnection while another is ordering equipment and a third is preparing for commercial operation.
NYISO and MISO Need More Grid Flexibility
New York and the Midcontinent are both seeing changes in generation and demand that increase the value of flexible storage resources. Batteries can respond rapidly to grid conditions and provide capacity, frequency regulation, renewable-energy shifting and other balancing services.
The role of storage is also expanding as electricity demand rises from manufacturing, electrification and data centres. A grid with more variable renewable generation and larger loads needs assets capable of moving energy across time and responding quickly to system stress.
Credit Facility Supports Battery Development Across Key Markets
Battery technology receives significant attention, but financing structures determine how quickly development pipelines become physical infrastructure.
A US$300 million portfolio-level LC facility gives KCE a financial tool that can be reused across multiple projects rather than being locked into a single asset. This is a sign that storage is maturing as an infrastructure class: lenders are increasingly supporting not only individual projects but also the development platforms behind them.
For Standard Chartered, the transaction increases exposure to a fast-growing part of the US power market. For KCE, it provides flexibility to progress projects without tying up equivalent amounts of cash in collateral.
Capital Deployment Will Track NYISO and MISO Opportunities
KCE will deploy the facility as projects advance through the NYISO and MISO development processes. The important milestones will be individual projects reaching final investment decisions, securing construction financing, ordering equipment and entering commercial operation.
The financing itself does not guarantee that every project in the pipeline will be built. Its value is that it removes one recurring capital constraint, improving KCE’s ability to keep multiple battery developments moving simultaneously.
