I thank the hon. Gentleman for his comments. I will come on to the detail of the renewable heat measures and the work undertaken.
The Department for the Economy in Northern Ireland undertook an extensive public consultation in the last year to ensure that revised measures could be introduced in time for new legislation to come into effect from 1 April 2019. The tariff levels set out in the Bill are based on an analysis of the additional costs and savings of operating a biomass boiler in Northern Ireland. The Department has also engaged with the European Commission in developing the long-term tariff. The Commission has indicated that it is not in a position to approve a tariff that delivers a rate of return higher than 12%. Recognising that a small number of participants with lower usage needs or higher capital costs could see returns below the intended 12%, the Bill makes provision for the introduction of voluntary buy-out arrangements.
I recognise that some scheme participants in Northern Ireland will be concerned about these new tariffs. Both the Department for the Economy and my own Department have heard their views in person and in writing in recent weeks, as I said earlier, and I empathise with those people and businesses across Northern Ireland.
