501. Deputy Jonathan O'Brien asked the Minister for Communications, Climate Action and Environment the estimated cost of doubling the grants, including the maximum grant available for the purchase of privately purchased electric vehicles. [51088/19]

502. Deputy Jonathan O'Brien asked the Minister for Communications, Climate Action and Environment the estimated cost of increasing the electric vehicle home charger grant by €100. [51089/19]

I propose to take Questions Nos. 500 to 502, inclusive, together.

The electric vehicle purchase grant provides grant aid of up to €5,000 towards the private purchase of a new electric car. Based on supporting 5,600 privately purchased electric cars in 2020, the increased cost of doubling the purchase grant would be €28 million or €0.56 million if the grant was increased by €100.

The electric vehicle home charger grant supports the cost of installing a home charger up to a maximum of €600 for purchasers of both new and second-hand electric vehicles. An extra €100 per home charger grant based on an estimated 5,000 grants paid in 2020 would have an increased cost of €0.5 million.
