Captive Power May Not Win Local Support for Data Centres
Some data centres are considering making their own electricity instead of using the regular power grid.
This is called going off-grid.
They would need generators and many other pieces of equipment.
Much of that equipment is already difficult to obtain quickly.
They would also need extra machines so the system can keep working if one breaks.
Having unused backup equipment makes the electricity more expensive.
The data centre could face even more costs if it later reconnects to the normal grid.
The argument is that building private power systems may not make nearby communities more supportive.
Going off-grid requires data centres to build their own power systems.
Operators must obtain generators and associated equipment, much of which is backlogged.
Private power systems need extra capacity to provide redundancy when turbines fail.
Redundancy can reduce utilization and increase the cost of each unit of power.
Costs may rise further if a data centre later connects to the regular grid.
- Who
- Big Tech and data-centre operators.
- What
- The article argues that captive, off-grid power systems may not improve local communities' attitudes toward data centres.
- Why
- Because building private power systems requires backlogged equipment, extra redundancy, and potentially higher costs.
- Power approach
- Captive or off-grid power for data centres
- Required equipment
- Generators and associated equipment
- Supply constraint
- Much of the required equipment is backlogged
- Reliability requirement
- Operators need extra capacity to replicate the grid's redundancy
- Cost effect
- Lower utilization can raise unit costs
- Potential additional cost
- Costs may be compounded if the data centre later connects to the regular grid
