MUA Chair Rob Callister will be quizzed about electricity prices in this week's House of Keys sitting.
Arbory, Castletown and Malew MHK, Jason Moorhouse, will ask by what percentage electricity tariffs will increase this year and in future years.
Mr Callister stated in Tynwald earlier this month that customers should expect a hike in electricity prices following the current crisis around wholesale prices.
He added that the Authority will continue to work to minimise the cost to customers.
