Electricity Supply: Dips in Voltage Supply to your home ( Brownouts )

Kippure

How many people in Ireland experience:

1. Brown outs at peak demand? Morning time roughly 7am to 9am. Evening time 5pm to 7pm.

A brownout is an intentional or unintentional drop in voltage in an electrical power supply system. Intentional brownouts are used for load reduction in an emergency.[1] The reduction lasts for minutes or hours, as opposed to short-term voltage sag (or dip). The term brownout comes from the dimming experienced by lighting when the voltage sags.

By County.

How would you know.

I'll ignore the obvious puns.

Sir Arthur Daley

Was thinking of a different brownout, nevermind..

Victor

The worst I ever get is the occasional flicker. In Ireland, there is normally plenty of generating capacity.

We don't get a morning peak, although there is a slight midday one. http://www.sem-o.com/Pages/default.aspx

My electricity is always piping hot when I get it.

Mostly in the Evening after 7pm lights go dim then brighten back up can be a few times a night no actual power outages unless there is a fault

What kind of poll doesn't allow us to say we do not experience brownouts? I never do. Voltage levels and continuity are excellent.

Sure Monaghan hasn't gotten electrickery yet.

Oh, and peak demand in Ireland is is between 17:00 and 19:00. Where did you get 19:00 to 21:00 from? Demand at 9pm is as low as 6am!

Check out the Eirgrid daily system demand reports.

Never experienced a 'Brownout' Ever. The only time there's an issue is when
There's an outage due to storm damage or whatever but that's hardly ESBs fault and it's never been off for more than an hour or too.

I stand corrected. My Fault.

snubbleste

I thought brownouts only occurred in north america..
We actually have a fantastic electricity supply system in this country. We take it for granted.

Sir Osis of Liver.

Only once ,after a Guinness session.

The Backwards Man

I voted for Dublin.

What was the question again?

Miss Lockhart

No. Don't ever remember one happening and I can't remember any blackouts in the last 10 years.

today's peak demand was 4GW , record demand ever was 5.09 GW

http://www.eirgrid.com/operations/systemperformancedata/windgeneration/
there was very little wind energy at noon, but by tomorrow we should be getting up to 1.5GW


We have oodles of spare capacity for the foreseeable future. Even if demand were to increase dramatically we could simply delay phasing out some plants

Brown outs are usually locally overloaded sections of the grid.

Oddly enough as we move to more devices with multi voltage SMPSU's they might not be noticed as much in future. CFL's, LED's shouldn't be as affected as much if the control electronics are up to scratch. Laptops and computers and TV's should keep going through temporary dips too. Heating systems have a long response time.


Big problem with the poll.

Dublin has 40 times the population of Leitrim and Cork is 9 times the size of Louth. West coast areas will get more storm damage.

Would be more meaningful if the polls contained more equal areas - perhaps based on constituencies outside the main cities https://en.wikipedia.org/wiki/Parliamentary_constituencies_in_the_Republic_of_Ireland

Or based on how far people are from their nearest substation

It's a poll to find out what county is the most averse to electrocuting their nipples.

Only recently would it happen that my lights would flicker.

Yes, the electricity network bears no relationship to the county boundaries at all.

As it is the network has been vastly improved in recent years.
I remember back in the 1970s when brownouts were almost an everyday occurrence if you lived in a remote rural location, every time the farmer switched on the milking machines the voltage would dip by about 20%

Peregrine

Never experienced a dip in voltage.

I vaguely remember not having electricity once though, like 4 or 5 years ago. The fault was fixed within an hour.

Also, the poll is stupid. The population of Ireland isn't evenly distributed between 25 counties and neither is the boards user base. Should be a simple yes or no.

Sh1tbag OToole

No problem with the power here except sometimes there is a bit of cryptosporidium mixed in with it

Just yesterday I was countin me electrons and there was definitely less than expected.

biko

Blackouts?
Brownouts?

Something smells racist here...

You must be a fair distance from the nearest substation, or next door the a major heavy industrial user.

I had a blackout last Saturday night, but when I woke up i noticed I had done a brownout on the bed

The thing about AC is that on average the electrons don't move, they just move back and forth.

If there's any missing it's defo some thievery at your end, I'd suggest CCTV

I have experienced several brownouts but they were usually preceeded by a rake of pints and a kebab

pizzathis

In the last week my tumble dryer has broke and the motor has gone in the Hoover I believe this is down to these brownouts when the voltage drops has anybody else experienced these issues
