A doctor has described power supplies to her Western Australian town as 'fourth world' after she had to dispose of vaccines for the third time in as many years.

Mullewa GP Nalini Rao said the latest electricity outage cut power to the surgery's refrigerator and a backup system also failed.

"It is quite a serious concern," Dr Rao said.

"I think this is fourth world country standards."

She said the power had been out in the town for 72 hours in one week, and on occasions over summer it would be lost for more than 24 hours.

"I had to discard my whole batch of vaccines which included about three dozen meningococcal vaccines, which the government had rolled out because of the outbreak in Geraldton recently," Dr Rao said.

"I am at serious risk of losing my permit to carry any further vaccines.

"I have made the decision not to carry any further childhood vaccines."

Mullewa is 100 kilometres from the regional city of Geraldton on WA's Mid-West coast.

She said parents could still have their children vaccinated by the child health nurse, but if she lost the ability to supply adult vaccines, including for influenza, it would have a significant impact on her patients.

"My biggest concern is the flu season, whether I will be able to obtain 300 or so vaccines I need to vaccinate the vulnerable in the community," Dr Rao said.

"This is a vulnerable population with a high diabetes burden.

"They do need a basic electricity supply."

Police station reliant on generator

The local police station has been forced to rely on a hired generator during extended power outages that officer-in-charge Chris Martin said sometimes lasted more than a day.

"We have had it on almost every second day for a period of at least 12 hours," Sergeant Martin said.

"The generator gives us the ability to power computers, telephones and just run the station to the minimum requirement."

Sgt Martin said the loss of telephone contact during blackouts was a concern for elderly residents and those on farms and stations.

"If you're out on a station somewhere and you have got no power to make a call on your landline, you have got no power to recharge your phone and an incident does happen … it would be very difficult to make the necessary contact," he said.

Sgt Martin said he and other officers had bought generators for their own homes to keep air conditioners and fridges working.

Mullewa mother-of-two Angela Mangano said she and her husband had paid $1,000 for a generator.

"I have lost quite a lot of food," Mrs Mangano said.

"I chucked out a ham yesterday because I cannot guarantee it is safe to feed my family because of the amount of time the power was off.

"Who plans for six outages in one week?"

Mullewa farmer Brendan Weir hooked up his spare generator to keep the power on at his elderly neighbours' home to ensure they at least had a telephone and fridge.

"It becomes a safety issue at their age without power," Mr Weir said.

Situation 'critical': mayor

Geraldton mayor Shane Van Styn said the yearly power problems were creating "great hardship" for the community during summer, and there were no alternative sources of power.

"If there was an alternative supply [for] back-up, people could continue to ensure their medications are kept cold, their food is kept cold and their mobile telecommunications are intact," Mr Van Styn said.

"This has reached a critical level of importance.

"We need the state government and Western Power to act to bring in some alternative generation capacity so lives aren't lost unnecessarily."

He said the towns of Perenjori and Kalbarri were trialling battery storage solutions and Mullewa needed to be included.

In a statement, Western Power said it understood the outages were "frustrating" but battery storage was not the answer.

"We are actively investing in additional maintenance for the area," the statement said.

"Unfortunately a battery energy storage system would not have been effective for all of the recent outages in Mullewa based on where the faults occurred."
