Coal-heavy (~585 g), expensive and small. Cleaning up slowly, but not a siting destination today.

Low availability for large new load.
Expensive power.
Negligible momentum.
High carbon (~585 g), coal-led.
Hurricane Fiona (Sep 2022) damaged nearly 3,000 poles and left multi-day outages across much of the province; Atlantic storm exposure with demonstrated slow restoration is the standing delivery risk.
What this means: A large new load should expect genuine exposure to forced power cuts (curtailment), price spikes, and delays in getting connected, and should design in backup power or firm supply contracts.

Coal must exit by 2030 against an 80% renewables target; grid-scale batteries at Waverley, Bridgewater and the Valley are the adequacy mitigant.
What this means: A large new load faces occasional exposure here. Monitor conditions and keep a contingency plan.

We have not compiled what firm service actually promises here: whether it is firm, non-firm or interruptible, the conditions under which you can be curtailed, the redundancy required of you, and the transfer time behind any N-1 commitment. Treat this as an open diligence item, not as an indication that service is firm.
Utility feeds, UPS, storage, on-site generation, islanding, black start and the residual energy you still expect to lose are properties of a specific site design, not of a market. This layer only exists once there is a site, and we never assert it for you.
What this means: Supply and demand look broadly balanced; the outcome hinges on the drivers below.

Freshness reflects each layer's refresh cadence: reliability annual to three-yearly, capacity-auction and queue yearly, tariffs every year or two. The full cross-market freshness dashboard is at /data-quality.
Not compiled for this market. Identify the serving operator before relying on any figure here, because a market-level read is an average over territories.
How the connection process is organised: the applicable service and connection entities depend on the candidate location and the power pathway. We have not compiled the structure for this market; that is a gap in our wayfinding, not a fact about the market.
How Nova Scotia's reliability-adjusted score and tier have moved, month by month. Part of your Analyst Desk.
Every field above carries its own source and freshness. Price, imports and exports are modelled in every market because no feed supplies them. Carbon intensity is derived from the fuel mix.

The national greenhouse gas inventory publishes a measured carbon intensity for Nova Scotia. It differs from the figure this page serves, and both are shown rather than one quietly replacing the other.
| Served here | ECCC inventory, 2024 |
|---|---|
| 600 gCO2eq/kWh hand authored undeclared basis | 585.9 gCO2eq/kWh generation intensity, Table A7-4, preliminary |
We publish 14.1 gCO2eq/kWh higher than the inventory measures. The fuel mix on this record is also unsourced and also differs: it states 22% gas, while Nova Scotia generated 25.75% of its electricity from gas in 2024. How much of the intensity gap that accounts for is not established, and differs by market.
Why we have not simply switched. Adopting the inventory figure changes the published carbon intensity on nine Canadian markets at once, which is a reviewed change here rather than an edit, and it is open. Either way nothing moves a tier, score, pillar or outlook: carbon intensity is not an input to the PGIQ Rating.
