Ireland just saw its all-time wind power record broken twice in the past 8 days 🥇🥈
Prior to December, we hadn't seen a new record for more than 18 months.
Unusual to see it broken over the weekend when demand is lowest and has already started to tail off before Christmas.

L'Irlande est le co-leader mondial en part de production éolienne terrestre.
Pour tout savoir : @greencollective.io 💪
L'Irlande qui fonce sur le solaire : 2 000 MW déjà installés, dont la moitié en toiture. 👍
Qui innove : une installation PV gratuite pour les "personnes médicalement vulnérables".👏

Renewable generation and discharging storage equalled 56% of yesterday's electricity demand, with a peak of 73% at 23:45. Fossil fuel generation (mostly gas) equalled 31% of demand. 0% of generation was exported, 14% of demand was met by imports.

Resurfacing Saturday's wind record again, just for any folks who may have missed it over the weekend... ⏰

Good. But not enough. There have been no new wind farms in windy West Cork for years. We could be exporting electricity to France and the UK, and making a profit.
🚨 At 5pm yesterday, wind power on the island of Ireland reached a new all-time high: 4675MW, or more than 75% of electricity demand at the time.
This breaks the previous record of 4671MW set just last week 😮

Mystery solved: SEMO moved to a new format for metered data.
If any notice was given, we (long-time, heavy SEMO users and frequent filers of republishing and other requests) missed it; so far, nothing helpful from SEMO via email.
Well, we'll be updating our pipeline, so... 🙄
Stay tuned!

A new Irish wind record was set Friday morning 🥇
We've been planning to highlight the top wind farms, examine dispatch down, and compare with the previous record from way back in March 2024. However, SEMO hasn't published unit-level data since *last Wednesday* 😲
Not sure what's happening!

A closer look at yesterday's all-time high for wind power:
- occurred during the Friday morning peak
- 4671MW, or about 75% of electricity demand at the time
- finally beats the 4629MW seen in March 2024
A green day for all the tellies and kettles during the Toy Show! 🪀
