Currents Ep341: Onsite Power Solutions for Data Centers
Host: Todd Alexander (Norton Rose Fulbright)
Guest: Rebecca McDonald (VP Sales, Data Center Energy Solutions, Bloom Energy)
Date: March 26, 2026
Episode Overview
In this episode, Todd Alexander interviews Rebecca McDonald of Bloom Energy to explore onsite power solutions for data centers, particularly in the face of surging energy demand fueled by AI workloads and grid constraints. Rebecca provides insight into the evolution of Bloom’s technology, its applications for data centers, reliability, deployment models, and how the market and regulatory landscape have transformed over the past two decades.
Key Discussion Points and Insights
Bloom Energy’s Evolution and Technology
- Mission Consistency:
- Rebecca emphasizes Bloom’s enduring mission “to make clean, reliable energy affordable to everyone around the world” [01:09].
- Technology Overview:
- Bloom offers solid oxide fuel cell solutions, converting natural gas to electricity without combustion, yielding high efficiency, low pollution, and minimal noise [01:13].
- Efficiency stands at 54% versus competitors’ 35-40% [03:15].
Market Drivers & Data Center Applications
- From ‘Want’ to ‘Need’:
- The demand for onsite generation has shifted from a luxury to a necessity as grid capacity lags behind data center expansion, particularly with rise in AI workloads [02:26].
- Modular, Scalable Deployment:
- Bloom’s approach leverages modular, factory-built units that are essentially “plug and play” onsite, speeding up deployment and lowering site risk [03:55, 09:04].
- Reliability Metrics:
- Bloom systems guarantee 99.9% uptime, with 2 million operating hours logged in off-grid “island mode,” maintaining power through hurricanes and wildfires [05:40].
- Over 170 microgrids deployed and nearly half a gigawatt currently installed [04:58, 05:09].
- Meeting Capacity Needs Quickly:
- Scalability allows Bloom to ramp up from its existing 1 GW annual production to 2 GW by 2026 [05:40].
Addressing Grid and Interconnection Challenges
- Filling the Power Gap:
- “We’re seeing scenarios where we’re pulling a gap and a bridge type for a shorter term capacity and then we’re also having conversations on the longer term.” [07:15]
- Bloom’s solutions help data centers overcome grid interconnection delays and transmission constraints, offering both short-term and 15+ year options [07:15].
Turnkey Delivery and Long-Term Service
- End-to-End Solution:
- Bloom acts as both the construction/installation contractor and the long-term operations and maintenance (O&M) provider [08:02, 09:04].
- Performance Guarantees:
- Rebecca highlights the firm’s commitment:
“We guarantee whether you’re at year five in the contract or year 10… we’re going to maintain that same level of efficiency…” [08:19]
- Proactive, remote monitoring allows preemptive maintenance for high uptime [08:19].
- Rebecca highlights the firm’s commitment:
Financing & Contracts
- Flexible Commercial Models:
- “We’ve got financial partnership where we can offer PPA [Power Purchase Agreement]… or you can do a capex agreement...” [09:44]
- Options include purchasing electrons from Bloom, traditional capital expenditure, or hybrid approaches with bundled O&M [09:44].
Regulatory & Incentive Landscape
- Qualifies for Clean Energy Tax Credits:
- Systems qualify for a 30% federal investment tax credit post-Inflation Reduction Act (“big beautiful bill” as referenced) [10:24].
- Minimal Permitting Burden:
- No NOx or SOx emissions mean systems typically do not require air permits, removing a major deployment hurdle [10:24].
Remaining Barriers to Scale
- Supply Chain Optimization:
- Historically, cost and supply chain were the primary barriers, but advancements have lowered both [11:12].
- Changing Role from Competitor to Complement:
- Previously, Bloom competed with utilities; now, it complements or fills capacity gaps as utilities can’t keep up with new demand [11:12].
Market Messaging & Value Proposition
- Speed and Strategic Value:
- Rebecca wishes the market understood not just Bloom’s reliability and speed to market, but also its ability to “help them impact and reduce some of their carbon footprint and their footprint in the data center” [12:26].
- Recent notable project: Delivered ahead of schedule for Oracle, with an initial timeline of just 90 days [12:26].
- Flexible Solutions:
- Ability to operate behind or in front of the meter, in grid-tied or islanded mode, supported by creative financing [12:26].
Notable Quotes & Memorable Moments
-
Rebecca McDonald on Mission:
"Our mission, right, since day one and it continues to be…to make clean, reliable energy affordable to everyone around the world." [01:09]
-
On Market Shift:
"Our customers right now need an alternative. It’s not a Want, it’s a need… we’ve kind of finally met our moment." [02:26]
-
On Reliability:
"We’ve powered already half a gigawatt… nearly 2 million operating hours in off grid island mode, maintaining uptime during hurricanes, wildfires, etc." [05:40]
-
On Speed to Market:
"Most recently we announced the speed to delivery with an Oracle project where we delivered a project ahead of time and our initial timeline was 90 days." [12:26]
-
On Market Evolution:
“Prior to the last couple of years, the utility was always an option. So essentially we’re competing with the utility. Now we’re complementing the utility or filling the gap for the utility.” [11:12]
