State of the grid13 Jan 2022 09:05
Simpering article in today's Irish Times about how Ireland's grid got to its parlous state:
"Like most major crises, there is not one single explanation for how it happened but rather a series of events that tend to reinforce and amplify each other. In Ireland’s case, specific factors around supply, demand and an ageing fleet of conventional power stations provided a coincidence of crises that brought us to where we are today. However, this predicament isn’t just about “bad luck”; at its core was a blindness to the need to build conventional power plants that allowed us to sleepwalk into a tight spot."
It goes on to contradict itself and say that actually, yeah, it's pretty simple:
"... renewables do not replace the need for fossil fuel power stations, which are required when weather-driven generation is low across Ireland and northwest Europe. This came into sharp focus in 2021 as, it was a relatively “low” wind year. Despite continued growth in wind power in 2021, wind energy provided about 30 per cent of our electricity over the year (compared with nearly 40 per cent the previous year). At the same time, the economy emerged from the Covid-19 pandemic restrictions, which allowed electricity demand to rebound quickly."
In other words, the greenies had been yakking on about 2020 being the proof that we could easily reduce emissions, when all it proved was that emissions will go down if you slaughter the economy. It also highlights the crazy fact that available wind power can vary by more than a third, even when averaged over an entire year. And finally, it shows -- unsurprisingly -- that when you disincentivise the conventional energy sector, investors won't be rushing in to finance conventional energy.
