- 00:04Right now, the world is in an AI race.
- 00:08Companies, governments, universities
- 00:11are all racing to build bigger models, smarter systems.
- 00:16And behind the scenes,
- 00:17they are racing to build more data centers to power AI.
- 00:22But there's a problem.
- 00:24We are running head first into the limits of our infrastructure.
- 00:28The power grid includes all the infrastructure,
- 00:31power plants, transmission lines and all
- 00:33to generate and deliver power to our homes, our businesses,
- 00:37and now to AI data centers.
- 00:40In the United States,
- 00:41the grid operators are reporting that new AI data center projects
- 00:46are requesting power loads equal to entire cities.
- 00:50In some regions, utilities simply can't keep up.
- 00:55So when you hear “AI data center,” what comes to mind?
- 01:00For many, it's one thing:
- 01:03energy hogs.
- 01:05And they are not wrong.
- 01:07AI is dramatically accelerating the electricity demand of data centers.
- 01:12Just training GPT-4
- 01:14is estimated to have consumed around the annual electricity use
- 01:19of thousands of US homes.
- 01:21In another striking example, in Ireland,
- 01:24nearly 20 percent of the nation's electricity
- 01:28is drawn by data centers today.
- 01:32And these are not just statistics.
- 01:35They are also community stories.
- 01:37In the data center alley in Virginia,
- 01:40residents recently saw higher electricity bills,
- 01:4420 percent higher already compared to just a few years ago,
- 01:48as utilities scramble to serve massive new AI facilities.
- 01:53So energy-hog label seems well deserved.
- 01:59But that's only half the story.
- 02:01Here is the new view.
- 02:04These facilities are not just energy-hungry brains.
- 02:08They can also be the muscles of the grid, flexing on demand.
- 02:14Unlike our homes or hospitals,
- 02:16AI data centers run jobs that are predictable,
- 02:21controllable and often delayable.
- 02:24That makes them ideal to help balance supply and demand on the grid.
- 02:30By making AI data centers power-flexible,
- 02:34we can connect them much more rapidly to the grid,
- 02:37while at the same time making electricity more affordable and resilient.
- 02:44What's more, the AI boom is arriving
- 02:48just as the renewable boom is also taking off.
- 02:52Wind and solar don't follow our schedules,
- 02:56but data centers can.
- 02:58Which means we can align the rise of AI
- 03:02with the rise of clean energy,
- 03:04if we are bold enough to rethink their role.
- 03:08All this transformation to power flexibility
- 03:12didn't just come out of thin air.
- 03:15It builds on decades of research
- 03:18on energy-efficient computing,
- 03:20scheduling, optimization and many others.
- 03:25I've lived this journey myself.
- 03:27Early in my career,
- 03:29I asked a question that many found unrealistic.
- 03:34Could computer systems adapt their behavior
- 03:40depending on power grid needs,
- 03:42but without breaking their performance promise
- 03:46to their users?
- 03:49At the time, this sounded radical
- 03:51because why would we ever design a system that would slow itself down
- 03:57on purpose?
- 03:59But then came the breakthroughs.
- 04:02First, we discovered
- 04:04not all computing tasks are urgent.
- 04:07Some can wait for minutes or hours,
- 04:10and some can be slowed down without anyone really noticing it.
- 04:15For example,
- 04:17a researcher analyzing hundreds of medical images with AI
- 04:22may be OK with waiting just a little longer.
- 04:25Or, if you are fine-tuning your AI model
- 04:28over the course of the next few days,
- 04:30you may be OK with slowing it down for just a few hours.
- 04:35This inherent flexibility in computing
- 04:38gives us the flexibility we need to manage power.
- 04:40Second,
- 04:42we reframed the problem.
- 04:45Instead of asking
- 04:47how do we compute as fast as possible,
- 04:50we asked,
- 04:52how do we make computer systems meet the constraints of the power grid,
- 04:57while at the same time still delivering on user performance agreements?
- 05:02This shift led to new strategies:
- 05:04capping power,
- 05:06shifting workloads
- 05:08and provisioning the data center as a flexible reserve to the grid.
- 05:13A key aspect here is that we do keep the performance promise to users,
- 05:18so it's not arbitrary.
- 05:20User experience remains as a key target.
- 05:24And better yet, it becomes more predictable.
- 05:28So we built prototypes on real data-center servers,
- 05:33and they worked.
- 05:34Systems that could follow a power target
- 05:37while still delivering results.
- 05:40But all this journey wasn't smooth.
- 05:42There were paper rejections, funding rejections,
- 05:47colleagues telling me this would never work.
- 05:51Well, since I was a kid, I was told I'm a persistent person.
- 05:55Perhaps stubborn at times.
- 05:58And bold ideas require persistence
- 06:03because change almost always looks impossible
- 06:07before it looks obvious.
- 06:09So you take that feedback, you reframe it again and again,
- 06:13and you keep building.
- 06:15You keep proving.
- 06:16So what began as scribbles on a whiteboard 12 years ago,
- 06:21is now running on real AI data centers.
- 06:25Why does this matter now?
- 06:26Because the power grids challenge
- 06:29isn't just to generate more power.
- 06:32It's about timing.
- 06:34Solar gives us a glut of electricity at noon,
- 06:39but demand might peak in the evening.
- 06:41Wind might be abundant one day and scarce the next.
- 06:45Nuclear takes decades and billions of dollars to build
- 06:51and is often hard to locate in urban areas.
- 06:55Batteries are critical,
- 06:57but scaling them is costly, slow,
- 07:01and often not environmentally clean.
- 07:03Meanwhile, AI data centers themselves face five to seven-year wait times
- 07:10just to connect to the grid
- 07:12in places like Virginia.
- 07:14In AI time,
- 07:15where technologies shift in a major way every six months,
- 07:18five to seven years is an eternity.
- 07:21So here's the opportunity.
- 07:23With the right orchestration,
- 07:25AI data centers can be flexible today.
- 07:28No waiting, no new massive power infrastructure construction.
- 07:33They can soak up excess solar in the afternoon,
- 07:38scale down at peak times
- 07:40and act as virtual batteries today.
- 07:43And the stakes are real.
- 07:44Take Texas, August 23.
- 07:47During a brutal heat wave,
- 07:50the rising electricity demand pushed the grid to its limits.
- 07:55Wholesale electricity prices spiked over 800 percent
- 08:00in a single afternoon.
- 08:02So flexible loads, if they were widely available,
- 08:06could have reduced the costs
- 08:08and could have prevented the emergency alerts that went to the consumers.
- 08:12So we have two opportunities here.
- 08:14One, we can make current data centers flexible
- 08:19and help prevent blackouts
- 08:20and reduce electricity costs.
- 08:23Two, and perhaps the more significant,
- 08:26by making future data centers power-flexible,
- 08:31we can connect them much earlier
- 08:33without waiting for major power grid upgrades.
- 08:36If we ignore this opportunity,
- 08:40we are not just wasting renewable energy
- 08:43and we are not just raising our electricity bills.
- 08:46We are also slowing AI adoption,
- 08:49making it delayed,
- 08:51more expensive and less accessible to society.
- 08:55But there's a catch.
- 08:58Orchestrating this flexibility is not easy.
- 09:02Prices change hourly.
- 09:05Workloads may arrive unpredictably.
- 09:08Grid rules change across states, across countries.
- 09:12So no human operator
- 09:14and no single fixed data center management policy can keep up.
- 09:18This is where AI itself comes back into the story.
- 09:23The very technology driving this unforeseen demand
- 09:27is also probably the only thing smart enough to tame it.
- 09:31AI can learn patterns, anticipate grid needs
- 09:36and coordinate across data centers, across utilities,
- 09:40even nations in real time.
- 09:43Imagine a data center
- 09:44or a whole network of them,
- 09:46as an orchestra,
- 09:48with hundreds of instruments, all playing at once.
- 09:52Left on their own, it can sound like chaos.
- 09:57But bring in a conductor,
- 09:59suddenly all that noise turns into music.
- 10:02The conductor in this case is AI.
- 10:06AI can direct data center operation
- 10:10so that the data center can precisely match power constraints,
- 10:15depending on what the grid needs, what power is available
- 10:19and what users demand.
- 10:21The result is harmony.
- 10:24Reliable electricity, efficient computing
- 10:27and a system that works beautifully together.
- 10:30And that's exactly what we've built.
- 10:33We built software that slows down, speeds up,
- 10:37or pauses workloads in a data center,
- 10:40or shifts workload among data centers.
- 10:43Our conductor platform tunes performance and power at real time,
- 10:49all the while respecting user and cloud-provider performance needs.
- 10:54In this way, by flexing when needed,
- 10:57we can connect AI data centers much faster to the grid.
- 11:03Make better use of the available power in the power grid
- 11:07and enable faster AI adoption.
- 11:11I've been inside this story
- 11:12from an idea that once seemed impossible
- 11:15to prototypes in a lab,
- 11:17to systems now running in the field,
- 11:19and I believe this is just the beginning.
- 11:21AI is already reshaping how we compute,
- 11:24but it could also reshape how we power the world.
- 11:28So the question isn't how much energy AI consumes.
- 11:33The real question is how much flexibility, resilience
- 11:38and clean power can AI unlock?
- 11:41If we are bold enough to rethink AI data centers,
- 11:44the very machines that now seem like a burden
- 11:48could be our greatest assets
- 11:50in building a sustainable AI future.
- 11:54Thanks.
