Work is underway to bring renewable energy to the remote northern group islands. Solar power projects have begun on Pukapuka and Rakahanga and in about three months, the construction teams will move to Nassau and Manihiki to start similar work. Huge concrete slabs are being laid for the solar panels and more than 12,000 metres of cabling is being installed on Pukapuka alone. LED street lamps will also be installed on Pukapuka, Rakahanga, Palmerston and Nassau as the project continues. But some islanders are concerned about the cost of the energy as meters are being put into homes to measure and charge for use.
