We are a UK business based in mid-Wales. Our staff have worked in renewable energy since the late 1980's and internationally since 2010.
The name comes from the Batak tribe in North Sumatera and means "Always full of good things". It reflects our work philosophy and our optimistic approach to finding appropriate solutions to individual situations.

We have worked with the Scottish and Indonesian Governments, supported by the British Council and Foreign & Commonwealth Office to work with remote and off-grid communities in SE Asia, developing systems for prawn farming, irrigation and salt production. We have designed insulation systems for UK houses resulting in 70% heating energy reduction and provided energy consultancy to hotels and waste management companies, as well as a BBC 2 program on energy reduction
