The wind farm mills along Ulupalakua Ranch quit working for a while today. Maui Electric Company says 19,258 customers lost power today at 12:34 p.m. for about 20 minutes when the Auwahi Wind Farm tripped offline resulting in a sudden and severe loss of wind generation on Maui Electric’s system.
The electrical system, which runs optimally at 60 hertz, dropped to about 15 hertz when 20.7 megawatts of power from Auwahi Wind went offline. The result was a brief flicker for some, a “brown out” for some and lights out for others.
As a result, MECO was forced to “load shed” customers in order to protect and stabilize Maui’s electrical grid. Presumably that means shutting down as many customers as it takes to operate efficiently for as many customers as possible until the windmills were powering again.
Customers affected included parts of Lahaina, Kihei, Kula, Pukalani, Speckelsville and Makawao to Hana. All customers were brought back online at 12:57 p.m.
No word yet on why the wind farm tripped off. The Auwahi Wind Farm is hidden from view from most areas of Maui.
UPDATE: MECO reports that power has been restored to all Moloka’i customers as of 7:09 a.m. today.
Maui Electric Company would like to inform the public that the Parts of Kaunakakai Molokai is experiencing a power outage. Maui Electric is working to identify the cause and restore electrical service as quickly and safely as possible.
An update will be provided as soon as more information becomes available. MECO expressed thanks for your patience and understanding.
Maui Electric crews have been busy in Central Maui this afternoon. In a 90-minute span, a large portion of Wailuku lost electrical power not once – but twice.
The first outage was around 2:45 p.m.. MECO had everyone back on within 30 minutes. But then – more flickering and a similar-sized outage cut the lights shortly after 4 p.m. This time electric order was restored within 15 minutes.
MECO expressed thanks for the patience of powerless customers – and has not released any details of the cause of the two blackouts.
UPDATE: Power has been restored to all Waikapu customers as of 3:34 p.m.
Maui Electric Company would like to inform the public that the Waikapu area is experiencing a power outage. Maui Electric is working to identify the cause and restore electrical service as quickly and safely as possible. The outage was first reported at 11:37 a.m. today.
An update will be provided as soon as more information becomes available. Thank you for your patience and understanding
HONOLULU – Residential customers who have or are considering an electric vehicle now have a new tool to estimate how much money they can save by using special timeof-use (TOU) EV charging rates offered by the Hawaiian Electric Companies. The new EV Bill Savings Estimators and instructions are accessible at:
“Plug-in electric vehicles are key to a clean energy future for Hawai‘i,” said Jim Alberts, Hawaiian Electric senior vice president for customer service. “EVs can help reduce our dependency on imported oil, reduce greenhouse gas emissions, and save customers money in the process.”
There are estimator versions for:
With a recent electric bill in hand, anyone can input data to discover the amount of savings from using the TOU EV rate. The calculation is illustrative, based on individual factors such as actual household electricity use.
Under the TOU EV rate schedule, the cost per kilowatt-hour for home charging varies depending on the time of day. For example, the O‘ahu TOU EV rate provides a discount of about 6 cents per kilowatt-hour for electricity consumed during off-peak hours from 9 p.m. to 7 a.m. Customers can still charge vehicles at any time, but rates are somewhat higher during other hours.
A typical customer with a battery electric vehicle can save about 30 percent on fuel cost by using the standard residential rate to charge at home compared to a non-electric vehicle fueled at the gas pump.* When applying the TOU EV rate, the Bill Savings Estimator will show an additional 15 percent savings for O‘ahu customers charging an EV at home.
The new savings estimators are part of the Hawaiian Electric Companies’ support for electrification of transportation that includes the discount TOU charging rates and companyowned fast chargers. Learn about EVs and signing up for TOU rates for EV charging at hawaiianelectric.com/GoEV.
