Mark Foley, former EirGrid CEO said Ireland’s digital sector is facing an “existential crisis” and data centres should connect to the gas network to generate energy on-site without delay.

A sunny Monday, and EirGrid's dashboard showing a new all-island solar high: 1402MW ☀️
However, it's too close to call: as our charts show, spikes in real-time data are often later revised down and/or disappear with downsampling.
Record or not, it's great to see such highs well into the autumn! ☀️

The Eirgrid dashboard now shows daily solar generation. Four years ago, this would have been a flat line.
This doesn't even include rooftop solar which reduces the demand on the grid.

"Electricity demand from data centres has grown from 5% of national electricity demand in 2015 to 22% in 2024.
According to Eirgrid, by 2034, it is expected that this, along with any other new technology-related energy drains, will rise to 34% of electricity demand." Source: @thejournal.ie

So, we can completely miss our climate targets but continue to build these energy sucking monstrosities. This needs to be stopped. Little to no employment, massive quantities of land and ridiculous damage to our air, water and habitats. #SpeirGorm
Minister for Enterprise Peter Burke will this morning bring a major plan to build more data centres across the country to Cabinet for sign off.

This is a significant move by the CRU and shows the risks of embedding data centres further into our grid.
The response by the industry also highlights that tech companies are not 'good energy citizens' that will provide public services for free. 1/2

Renewable generation and discharging storage equalled 72% of yesterday's electricity demand, with a peak of 81% at 04:45. Fossil fuel generation (mostly gas) equalled 31% of demand. 3% of generation was exported, 0% of demand was met by imports.

Earlier this month, output from solar farms started exceeding 1GW for the first time.
Yesterday, we saw another important record set: around 1pm, solar output was equal to almost a quarter of the island's electricity demand.

We were headed for full, unbroken 7 days of renewable generation meeting the majority of electricity demand - but the streak broke this morning.
BUT, renewables met 75% of electricity demand Monday-Friday: very rare over 5 consecutive days and something we haven't seen since late 2023.

EirGrid released their January report. For anyone wondering why our figures differ so much: looks like EirGrid mixed all-island wind numbers with (incorrect) ROI demand numbers to calculate their wind/demand ratio 🙃
