Energy Secretary Ed Davey and Scottish Energy Minister Fergus Ewing will both speak at next month’s All-Energy event in Aberdeen.
The two-day event, which has become the UK’s largest renewables show, will take place at Aberdeen Exhibition and Conference Centre, Wednesday and Thursday, May 22-23.
It was attended last year by more than 8,300 people from 49 countries.
Jonathan Heastie, of organiser Reed Exhibitions, said: “Each year, All-Energy provides an unparalleled opportunity to see the latest cutting-edge solutions, hear about policy and technology developments, source new partners and suppliers and participate in networking events.”
He added that more than 3,000 people had already registered to attend, with stand space up from last year when 580 firms and organisations exhibited.
The exhibition will include three seminar areas and three dedicated zones for business energy efficiency, low-carbon transport and jobs.
Judith Patten, the event’s project director, said: “The conference programme encompasses all renewable and sustainable energy sectors, business energy efficiency and also looks at the challenges and opportunities facing the industry.
“Our speakers read like a ‘who’s who’ of the renewable-energy sector and we know there will be lively discussion in many of the sessions.”
The conference programme includes seven sessions on offshore wind, seven on wave and tidal power, with further sessions aimed at those involved with community renewables.
