Discounted TVs and fridges would be available for low-income households in a $40 million plan to upgrade energy-sapping electrical goods if the opposition wins the state election.

Victorian Liberal leader Matthew Guy will announce the scheme, which he says will save 85,000 households up to $325 a year, in Melbourne on Friday.

The scheme – which will be available to pensioners, health care or concession card holders – would see the price of some flat-screen TVs halved. Fridges would be 40 per cent cheaper.

"Many Victorians who are doing it tough financially have ageing and energy-inefficient TVs and fridges but can't afford the cost of replacing them with energy saving models," Mr Guy said in a statement.
