What Has Baseload Ever Done For Us?

New Zealand, North Island

Outside of social media and partisan energy commentary, there’s only one, perhaps two, meanings of the term ‘baseload’ which matter to the normal people who pay for electricity each quarter.

It means that it’s there to serve demand when there’s demand.

This is the meaning used by the rational proponents of energy projects which have dispatchability designed-in from the start.

What is “dispatchability?”

Dispatchability means we know we can rely on the resources in the system if we need to ‘dispatch’ or send instructions for them to act in a particular way at any time.

So why does ‘baseload’ get dismissed as a myth?

Predominantly, because it has also long been used to describe nuclear energy. Some people really don’t like to hear anything positive about nuclear energy, and this includes the idea that it’s practically always on, constantly serving demand.

Why is this so important? Because other people can point at nation-size electrical grids and immediately see a) a slab of nuclear ‘baseload’, and b) dramatically low emissions intensities.

Finland: 84 gCO₂e/kWh
France: 43 gCO₂e/kWh
Sweden: 35 gCO₂e/kWh
Ontario: 32 gCO₂e/kWh
Belgium: 179 gCO₂e/kWh

Belgium is a bit higher thanks to the share of gas. In this era of climate emergency the “plan” is, bizarrely, to replace that nuclear ‘baseload’ with more gas.

We dismiss the success of the past, and the true nature of current changes, at our peril.

This isn’t an intentional effort to entwine the terms ‘baseload’ and ‘dispatchable’ — they already are. It’s certainly not to champion ‘baseload’ as the silver bullet

The term “baseload” seems to have taken on almost mythical, magical qualities in recent years — representing (to some) all that would serve to fix the current train wreck unfolding in the energy sector, or (to others) representing all that ails the same energy sector.

… or even overwhelmingly necessary in its traditional form.

This isn’t about technical definitions. It’s about semantics, the implication of the regularly-used term. So take care when people police the use of ‘baseload’, and when they tell you what you see with your own two eyes is mythical.

It’s real, and it has helped us immensely.
