Bloom Energy [NYSE: BE]
Supporting Uninterrupted Operations with Continuous Onsite Power

A power outage does more than darken a facility. It can interrupt semiconductor production, compromise sensitive research, threaten continuity in hospitals and disrupt data infrastructure.

For over 25 years, Bloom Energy [NYSE: BE] has provided onsite energy solutions that generate electricity directly at customer facilities, strengthening power availability for critical loads while reducing dependence on transmission and distribution infrastructure.

Bloom Energy’s Energy Server, a solid oxide fuel cell platform, supplies onsite electricity during normal grid conditions, reducing the amount drawn from the utility. When an outage occurs, its AlwaysON microgrid platform disconnects from the grid and continues powering designated loads, allowing the same system to serve routine demand and resilience needs.

A standby generator usually starts working only after the outage begins. Bloom Energy’s system is already running when the grid fails, avoiding cold-start and load-transfer delay. Protected loads can stay powered through longer disruptions, including public safety shutoffs that last more than five days.

The Science behind Efficient Onsite Power

Bloom Energy’s Energy Server converts fuel directly into electricity through an electrochemical process without combustion. Its architecture accepts natural gas, biogas, blended hydrogen or hydrogen, allowing customers to begin with available fuel and preserve a route toward cleaner inputs. This flexibility keeps the power system useful as supply contracts, emissions targets and local fuel availability change over its service life.

Its latest Energy Server 6.5 can deliver 325 kilowatts of net AC output. Units can be combined into larger installations without replacing the underlying architecture, allowing customers to match initial capacity to present demand and add blocks as a campus, plant or data center grows. The modular design also creates fault tolerance because individual elements can be serviced without taking the entire generation system offline. The use of multiple independent power modules allows individual components to be serviced without interrupting electricity generation and support availability of up to 99.999 percent.

The Energy Server 6.5 delivers a cumulative electrical efficiency of 65 to 53 percent on a lower heating value basis. During normal operation, it uses no water and produces negligible sulfur oxide emissions. Heat above 350 degrees Celsius can also be recovered for heating or industrial processes, raising total system efficiency above 90 percent when electrical and thermal outputs are used.

From Grid-Tied to Grid-Independent

In grid-parallel mode, the fuel cells provide steady onsite generation, helping limit exposure to utility consumption and rate escalation. When the system shifts to island mode, control equipment disconnects the protected load from the utility and keeps the microgrid supplying electricity independently, with minimal to no interruption for the configured load.

This load-following capability takes the model beyond flat baseload demand. Bloom Energy combines its fuel cells with inverters and supercapacitors to handle rapid changes. For AI-style demand testing, the capacitor banks discharges immediately during a step increase and the fuel cells rise to the new target, and the capacitors recharges for the next event. As demand falls, the system seamlessly reduces output.

Bloom Energy customizes each Energy Server deployment to the loads at a particular site where it matters most. A hospital might need to protect clinical circuits, a manufacturer might focus on essential process equipment, and a data center might set aside capacity for abrupt changes in computing demand. One architecture can be used for different continuity needs without having to force every facility into the same setup.

Capacity that Expands around the Customer

Bloom Energy’s building-block model separates power growth from a single large construction decision. Customers can start with the capacity required for an initial building or production line, and then expand toward tens or hundreds of megawatts as demand rises. Its platform can be installed and running in as little as 90 days, where site, fuel and interconnection conditions permit, shortening the wait for new capacity.

Delivery covers more than just the fuel cell modules. Bloom Energy manages installation, system operation and maintenance as well as remotely monitors performance. Gas conditioning, power generation and grid interconnection can be organized within one project scope. This arrangement reduces the number of handoffs a facility must coordinate and gives the customer one accountable party for long-term equipment care and performance support.

Cost predictability is enabled through the creation of a greater proportion of energy locally. It provides buildings capable of offering a predictable pricing system along with fuel prices that are guaranteed, consequently reducing the unpredictability of utility costs.

Evidence across Demanding Facilities

California Institute of Technology faced the problem of safeguarding its research work from power failures while having a flexible arrangement for electricity with the utility provider. However, depending only on the grid was not sufficient to meet the need for specialized load-following power. The solution came from Bloom Energy with the help of its 1.2-megawatt Advanced Bloom Microgrid. Two sets of inverters divided the load, with one following the protected microgrid demand and the other operating in parallel with the utility.

In another instance, JSR Micro applied Bloom Energy’s model to semiconductor materials manufacturing, where a production outage can create lengthy recovery time and disrupt customer supply. Its 1.1-megawatt Advanced Bloom Microgrid powered manufacturing, testing, measurement and other critical facilities independently from the grid. Continuous onsite generation gave them a way to keep production and quality equipment running through external power disturbances.

Bloom Energy’s recognition as the Top Advanced Microgrid Solutions 2026 reflects its ability to combine continuous onsite generation, modular capacity expansion, fuel flexibility and managed deployment. Together, these capabilities help facilities maintain reliable power through grid disruptions while adapting capacity to changing demand.
