National Grid estimates power will be restored by 9:15 p.m.

UPDATE 9:57 p.m.: National Grid reports that power has not yet been restored and that crews are "re-assessing condition."

UPDATE 10:30 p.m.: Since the last update, power has been restored.

The driver behind the wheel of a minivan that struck a utility pole Wednesday afternoon on Law Street, causing a significant power surge in the area, has not been located yet.

Sgt. Mitch Cowen said Thursday morning that police are pretty confident they know who the driver was, that he's not from the area and that the vehicle was not stolen.

Cowen said police are looking for him in order to question him about the accident.

Witnesses saw the man running from the accident and provided a description to police.  A K-9 was deployed shortly after the accident in an attempt to find his trail, but that effort failed to find the driver.

At least 287 homes in the area of Chestnut Street, South Jackson, and to both the north and south of those streets, lost power.  The power surge caused electric meters on the outside of dozens of homes to blow out, with some of those houses displaying visible black char marks around the meters. 

National Grid crews worked through Thanksgiving morning restoring power.  The pole and main power line to the area were in working order by 10 or 11 p.m. on Wednesday night after crews worked to restore power to each house one at a time.  The meters on all 287 homes were replaced.  For residents who were not home last night, crews returned Thursday morning to locate them and complete the work (power at the breaker box needed to be turned off before the meter was replaced).

"When high voltage lines are negatively impacted, as they were last night, it can create an unsafe condition for residences," said David Bertola, a spokesman for National Grid. "The pulling, checking and replacing of electric meters is a standard safety procedure that our crews perform under circumstances such as these."

A worker last night recommended residents check all surge protectors. He said residents would know right away if the surge protector was blown.  If they were off before power was restored, when turned back on, if blown, they will spark and smoke. If already plugged in, they may no longer work.  Some may work but should have a light to indicate they no longer provide surge protection.

Each surge protector is rated differently. Some surge protectors can handle larger bursts of energy but can never exceed their rated capacity, and the capacity is cumulative. As HowToGeek.com notes, if a surge protector is rated for 1,000 joules of energy and it gets one joule at a time over a period of time, it will need to be replaced after 1,000 incidents.  If a highly rated surge protector takes a major power surge, it may still function but it may also be near the end of its life span.

Replacing all surge protectors after a major power event is often recommended by experts.

The Batavian spoke to an electrician today who recommended checking all appliances.  Anything receiving an active electrical current at the time of Wednesday's surge could be toast, or close to it.

At least one resident in the area is without heat after the power surge damaged the circuitry of the forced air heater.

A National Grid crew member advised residents who suffered an economic loss as a result of the power surge to file a claim with National Grid.

Bertola said customers with claims can email National Grid at ClaimsDept@nationalgrid.com or by calling (315) 428-6536.

A law enforcement source said that typically, National Grid attempts to recover damages from the driver's insurance company -- and it appears this driver was insured -- when an accident damages a utility pole.

The damages, in this case, could include the pole and all of the subsequent residential repair work and any damages sustained by residents.

National Grid has estimated that the outage is expected to be restored by 4 p.m. Wednesday.

the outage area is from Walnut to Lehigh Avenue, south to the city line and north along Ellicott Street with a portion going north of Main Street at Bank. 

National Grid expects to restore power by 8:30 a.m. 

It was first reported at 11:43 p.m.

National Grid expects to restore power by 1:45 a.m.

The outage is approximately from Tops on the west side, along West Main to Ellicott Street at Swan Street, north nearly East Avenue, cutting diagonally toward the State School for the Blind to nearly the Thruway.  It takes in both sides of Oak Street from Main to the Thruway.

UPDATE 12:36 p.m.: There are now fewer than 700 customers without power.  Power appears to have been restored to customers south of Main Street.

A crew has yet to be assigned. There is not yet an ETA for repairs.

A dispatcher informed Batavia PD that several traffic lights are not functioning in the area.

UPDATE 11:08 a.m.: Dispatch has received calls from people concerned about the light being out at Route 33 and Batavia Stafford Townline Road. The concern is that people "coming over the hill" will not see the lights are out. A trooper is advised but the dispatcher said callers have been advised multiple lights are out in the area and law enforcement may not be available for that specific intersection.

UPDATE 11:21 a.m.: Statement from Batavia PD: "There is currently a power outage affecting some areas of the City. Remember that if you approach a traffic signal that is not functioning to treat it as a 4-way stop."

UPDATE 11:30 a.m.: The estimated power restoration time for the Batavia-to-Byron outage is 1:15 p.m. For the outage to the east, the restoration time estimate is 12:45 p.m.

UPDATE Noon: Statement from National Grid -- "Earlier today a faulty piece of equipment at a substation resulted in the loss of electricity service for around 4,800 customers in the Batavia area. Our crews are making repairs and they should all be restored at around 1 p.m."

UPDATE 1:41 p.m.: It appears power has been restored to both areas.

Power went out at about 4 p.m.

It's the only significant power outage in Genesee County but there are also three large outages reported just to the east in Monroe and Livingston counties.

We don't have information on what may have caused the outages.
