Five ways to supply a data center
The first five arrangements decide where the energy comes from. A site can take grid power with standby generation on site, or run a temporary plant until the grid connection arrives. It can build its own plant and cap what it draws from the grid. It can take power from an existing plant next door, or run as a private grid and tie in later. Each one carries its own equipment, permits and lead times.
What the sixth arrangement adds
The sixth arrangement adds grid capacity alongside the data center's 24/7 supply. Energy systems in nearby homes and businesses discharge, and flexible loads use less, in the hours the grid is short. A data center that wants to connect sooner can fund that flexibility. Where a program exists, the homes and businesses that take part are paid for the flexibility they already hold, on terms the program or the agreement sets.
Why location decides the value
A grid limit sits on one piece of equipment, such as a substation or a transformer. Homes and businesses help most when they sit on the same part of the grid as that limit, at the hours it peaks. A credible plan names the constraint, its season and its hours before it counts any capacity. Why battery location matters explains feeders, transformers and phases.
How much capacity counts
The capacity that counts is what the utility or program accepts, and it usually sits below the sum of the ratings. Owner reserves, offline units and technical limits all pull it down. A home that offers 4 kW for four hours needs 16 kWh of usable energy left after its reserve. A single home system can offer less. Proving a virtual power plant delivered what it promised works through an example.
Existing equipment and new installs
Enrolling energy systems and flexible loads that homes and businesses already own is the lighter path, because it is already in place. A data center can also fund new systems in homes that have none, which gives the household an asset as well as adding capacity. That is a larger commitment, and a plan that funds new installs counts capacity and household benefit as two separate budgets.
What the utility has to accept
The utility decides whether capacity from nearby homes and businesses counts toward a data center's connection, and how much. Program acceptance, connection approval and customer consent are three separate decisions. In B.C., the 2026 Call for Demand states curtailment as a cut in the project's own demand. A project confirms with BC Hydro before it counts anything else. Connecting a large load in BC covers the call.
Where Elastic fits
Elastic works with the systems homes and businesses already have, from multiple manufacturers. The Energy Router schedules each system in the hours a program sets, within the reserve the owner keeps. Each event is recorded from start to outcome, so the flexibility can be counted. How dispatch is validated explains how a dispatch is checked against the metered response.
A few useful answers.
Can capacity from nearby homes replace a data center's energy supply?
It works alongside that supply. It lowers the grid's peak in the hours the grid is short, and the data center keeps buying its everyday energy.
Does funding nearby homes guarantee an earlier connection?
No. The result depends on the utility's constraint, its tariffs and your plan. Get its written terms for how it counts that capacity before relying on it.
