The six-figure brief focuses on Generation Green, a programme linking up with schools nationwide to educate children on the issues of energy and sustainability.
"The work is to engage people in how complex it is to deliver energy, and connect with children and their families with all stages around energy creation," said Kaper founder Chris McCafferty.
The shift of the work from Blue Rubicon, which repitched for the account, has not affected its role as lead agency handling the energy giant’s consumer and corporate PR.
The Generation Green campaign, run in conjunction with the National Schools Partnership, is aimed at Key Stage 1 to Key Stage 3 pupils and stretches across more than 13,000 schools.
It involves a range of activities spanning from the installation of energy-saving equipment in schools through to provision of educational resources for teachers.
Emphasising a real drive on the digital side of the campaign, McCafferty added: "It is about creating a programme that ties the range of Generation Green activities together and helps create a narrative for it."
