Switching Costs of Installed SystemsNarrow moat

The switching costs attached to Bloom's installed systems are the source of the moat's stickiness, and they are genuine. Installing Energy Servers is a substantial commitment: the customer sites them, connects them to fuel and electrical infrastructure, integrates them into its facility's power and operations, and builds a service relationship around them. Having made that investment and adaptation, the customer faces real cost, disruption, and risk in ripping the systems out to switch to a competitor's solution — so, within the life of the installation, customers tend to stay with Bloom, continue paying for service, and, when systems need replacing or capacity needs expanding, often turn to Bloom again. This is a real switching-cost moat of the kind that makes revenue sticky.

The stickiness is reinforced by the service relationship and the operational trust it builds: a customer whose Bloom systems have run reliably, and who values the established support relationship, has incentives to stay beyond the pure cost of switching. This is the mechanism that could, as the installed base grows, give Bloom a durable hold on a large base of customers. The qualifier is that switching costs in this business are strong within a system's life but fade at its boundaries: when a service contract comes up for renewal, or when a system reaches the end of its useful life and must be replaced anyway, the customer is free to re-evaluate the whole decision against whatever alternatives then exist — grid, turbines, batteries, rival fuel cells, or new technologies. So the lock-in is real and valuable but cyclical rather than permanent, holding customers through a system's life but reopening the competition at each renewal or replacement. The switching costs are one of the best things about Bloom's business and a genuine source of moat — but they are the kind that must be re-won at intervals, not the kind that hold a customer forever — a distinction that matters under a ~$20B backlog of future re-winnings¹.
