SYNERGY maintains big bills experienced by residents in the Baldivis area are caused by seasonal usage.
The electricity supplier held information stalls in Baldivis Stockland shopping centre and Rockingham Central at the request of Baldivis MLA Reece Whitby.
Concerned residents could bring their bills to Synergy staff and learn power saving tips.
On March 27, a Synergy spokeswoman said recent investigations reflected an increase in seasonal usage.
There were no billing or metering issues identified.
“About 40 customers took the opportunity to use Synergy’s mobile Energy Tool, with staff on hand to assist them to better understand their bills and help with queries relating to the installation of solar systems,” she said.
The Energy Tool is on Synergy’s website Energy tool.
“If customers have any concerns relating to the account, they are encouraged to contact Synergy on 13 13 53 and we’ll be happy to investigate their individual circumstances and compare their usage and billing to that of previous periods,” the spokeswoman said.
Residents gathered in a local park in March to speak with Mr Whitby about their bills and usage, many of which had nearly doubled since the previous summer.
People can refer their case to the Energy and Water Ombudsman at Ombudsman.
