HECO restores power after morning outage

By Star-Advertiser staff

LAST UPDATED: 09:20 p.m. HST, Apr 02, 2013

<br />star-advertiser 2010<br />Electricity rates in four counties rose slightly in February and March. This is HECO's building on Ward Avenue.<br />

Electricity went out for about 75,000 Hawaiian Electric customers in pockets of Central, West and Windward Oahu late this morning but now been restored, a Hawaiian Electric Co. official said.

HECO implemented the temporary outages as a precautionary measure after a 180-megawatt generating station owned by independent power provider AES went down at about 10:30 a.m., HECO spokesman Darren Pai said.

“It was a precautionary measure to prevent potential damage to the system and it’s part of an automatic process that’s built into the way the system is operated,” he said. The action helps rebalance the supply and demand for power on the grid and prevent a potentially larger and longer outage.

The AES unit, at Campbell Industrial Park, is the largest power generating station on Oahu, Pai said. It was supplying 23 percent of Oahu's power at the time it went down.

Power was restored to most customers by 11:09 a.m., except for a few customers who had their electricity restored shortly afterward, Pai said.

"The company is trying to determine how many people were affected in what communities, and what caused the outage." Answers: 1. Too many people; 2. Stupidity.

And will SA follow up tomorrow and actually ask HECO what the cause was? No. Heaven forbid there should be accountability. Another day, another hour and half power outage with no explanation.

Why is this HECO's fault? Didn't the article say it was AES that went down? Ask them what happened over in Campbell.

They buy AES's electricity - in this case, 23% when it went down. That causes a big imbalance in the whole system, and they purposely take areas offline until they can get backups to balance the system. Once that is in place, areas are added back online.

You know this is going to get worse, right? As this island's population begins to saturate our resources we can expect more of these outages.

Every time power goes out, the PUC needs to document it, and I am sure they already do that, determine the cause, and find remedy. If not, then please deny Rate Increases.

Why did not the spinning reserve of other generators pick up after AES tripped? This outage should have never happened. Watch them blame it on the wind and PV! AES isn't even the biggest plant. How close were we to yet another total black-out? PUC and CA need to investigate!

AES is the largest generator on the island. It is always the highest loaded because it is the cheapest source of energy and it keeps rates lower. FYI once the frequency falls to 59.3HZ over 100MW of PV will drop out causing the frequency to drop even more. These PV systems were not designed for small island system like we have here. The more spinning reserve there is the higher rates go to run idling generators. Get your facts straight before you point fingers.

For your information, AES --> IS <-- the largest generator on the island. Go look it up and then put your foot back in your mouth. You know that saying, better to be silent than to open your mouth and remove all doubt? This saying was made for people like you. Anyways, if you had read the article HECO's spokesperson explained why the outage was necessary, to prevent a larger and longer outage. That is the exact reason because a large frequency deviation can cause extensive damage. If you want to find out exactly why AES tripped well you're going to have to ask them. BTW, when AES is offline, everyone's rates go up. They make the cheapest electricity by far on the island burning coal. But allowing them that benefit to produce this large a portion of the island's power sources and pass on the savings to you, the big drawback is when they suddenly go offline the grid and everyone else is going to feel it just like today. Take the good with the bad.
