## Resource

A year ago the data centre conversation was about scale. Increasingly it is about what happens when the announcements meet the physical grid. New capacity is being announced at roughly 435 megawatts a month, enough to power a city of 400,000 people, but two-thirds of that committed load tends to disappear the moment utilities ask for a financial commitment behind it. AI training facilities create load profiles that drop 30% in five minutes, or 190 megawatts in three. The grid's mechanical inertia is retiring just as hyperscaler ambition accelerates, and regulation is lagging on both sides of the meter. In this episode, interim host Bridget van Dorsten returns the microphone to host Sylvia Leyva Martinez. The two recap six months of the show through clips from Chris Seiple (Wood Mackenzie), Tom Falcone (Large Public Power Council), Akhil Batheja (Bloom Energy), Kay Aikin (Dynamic Grid), Kristina Carlquist and Christian Payerl (ABB), Shannon Miller (Mainspring Energy) and Nick Chaset (Octopus US), and map out the questions that will shape Sylvia's return. The central tension of the past six months: announcements are racing ahead, but utilities, regulators and the physical grid cannot move at hyperscaler speed. A data centre can be built in two years. New generation takes five to ten. That mismatch is why developers have stopped waiting on the grid: 35% of US data centre project capacity announced in 2025 was planned with around-the-meter generation, and 92% of bridge prime power deals are now struck before the end tenant is signed, inverting the usual logic of infrastructure development. But collocated power is still, in Bridget's framing, a science project. The load behaviour demands a coordinated portfolio: supercapacitors and UPS catching millisecond swings, synchrono…
