Data Centres Face Water and Power Fees

Full Title:
Data Centre Water and Ratepayer Protection Act

Summary#

The bill would create new rules for large data centres in Nova Scotia. It would limit their water use and require them to pay the full electricity-system costs linked to their operations, including some costs if a project is cancelled or closes. The stated policy goals are to protect water resources and prevent other electricity customers or taxpayers from covering data-centre costs.

  • Data centres using more than a future water-use limit would need conservation measures or would have to pay a mitigation charge.
  • Mitigation-charge revenue would support water and wastewater infrastructure, water conservation, and water-resource protection.
  • Data-centre operators would have to pay their full electricity costs, including new infrastructure and certain cancellation or closure costs.
  • Electricity providers would need approval from the Nova Scotia Energy Board before committing capacity or major spending for a data centre.
  • Operators would need to provide advance payments or financial security for expected unpaid costs.
  • Operators would have to meter and report their water and electricity use.
  • Violations could lead to fines of up to $1 million for a corporation or $100,000 for an individual, with each continuing day treated as a separate offence.

What it means for you#

  • Data-centre operators: You could face new water-use limits, mitigation charges, reporting duties, inspections, and large financial-security requirements.
  • Electricity customers: The bill is intended to prevent data-centre costs from being recovered through higher rates for other customers. The bill would also prohibit public bodies from transferring an operator’s obligations to the public.
  • Municipalities and taxpayers: Municipalities and the provincial government could not provide financial assistance that pays or transfers a data centre’s obligations under the bill to the public.
  • Water users and communities: If a data centre exceeds the future water threshold and pays a mitigation charge, that money would be directed to water infrastructure and conservation. The bill does not set the threshold or charge amount.
  • Electricity providers: Providers would need agreements approved by the Energy Board before reserving capacity, making certain investments, or starting or expanding service for a data centre.
  • Government and regulators: Inspectors could examine non-residential premises, systems, and records. The Energy Board could order a safe reduction or disconnection of electricity service to enforce the electricity-cost rules.
  • What is unclear: The bill does not say when its requirements would start. The government would set the water threshold, technical standards, and mitigation charge later through regulations.

Expenses#

The bill may increase costs for data-centre operators and administrative costs for regulators, but no overall public cost estimate is available.

  • Data-centre costs: Operators would pay for electricity, reserved capacity, supply and reliability services, system costs, new infrastructure, and certain costs linked to cancellation, delay, reduced demand, disconnection, or closure.
  • Financial security: Operators would need advance payments or enforceable financial security for reasonably foreseeable unpaid liabilities.
  • Water charges: Operators that do not use an approved water-conservation approach could pay a mitigation charge. The amount is not provided.
  • Public costs: The bill does not provide an estimate for inspection, enforcement, Energy Board review, reporting, or auditing costs.
  • Possible public savings or avoided costs: The bill is designed to reduce the risk that other electricity customers or public bodies would pay data-centre-related costs.
  • No publicly available information about the bill’s total financial impact.

Proponents' View#

The bill appears intended to ensure that large data centres pay for the public infrastructure and resources they use.

  • A possible argument for the bill is that water-intensive data centres should help pay for water and wastewater infrastructure and water-resource protection.
  • Requiring closed-loop cooling, recycled water, or other conservation technology could reduce pressure on water supplies.
  • Full cost recovery could protect other electricity customers from paying for infrastructure built mainly for a data centre.
  • Advance payments and financial security could reduce the risk of unpaid costs if a project is cancelled, closes, or becomes insolvent.
  • Metering, reporting, inspections, and audits could improve accountability for water and electricity use.

Opponents' View#

No specific critics' statements were supplied. Possible concerns based on the bill include:

  • The water-use threshold, conservation standards, and mitigation-charge amounts would be set later. This makes the bill’s direct effect difficult to assess now.
  • Requiring operators to pay future infrastructure and closure-related costs could make data-centre projects more expensive or harder to finance.
  • The bill does not estimate the cost of financial security, audits, reporting, inspections, or regulatory reviews.
  • The Energy Board could order a reduction or disconnection of service. The bill does not clearly explain the process, notice, or appeal rights for such an order.
  • The bill gives the government and the Energy Board broad authority to set requirements later through regulations and agreements.
  • It is unclear how the rules would apply to existing data centres, projects already under development, or facilities that only partly meet the bill’s definition of a data centre.
