Managing Director Paulinus Shilamba said yesterday in Windhoek, when he gave an update on the power supply situation in the country, that the project to install one million LED bulbs in residential houses will be done through funding institutions. The project also involves the replacement of 20 000 electrical water heaters with solar water heaters in residential houses through a rebate initiative.
A LED lamp is a light-emitting diode (LED) product that is assembled into a lamp for use in lighting fixtures. LED lamps have a lifespan and electrical efficiency that is several times better than incandescent lamps, and significantly better than most fluorescent lamps, with some chips able to emit more than 100 lumens per watt.
Shilamba said the campaign will be executed by contracting companies, that will recruit individuals to perform house to house replacements.
“The free installation of LED lights will be implemented through two phases, with the first phase to be limited to two towns as a pilot project and the second phase, which is the last phase, to be rolled out to the rest of the country depending on the outcome of the pilot phase,” he said. Shilamba said this campaign is expected to reduce the peak demand by 30MW.
He said another campaign is to replace 20 000 electric water heaters with solar heaters over the next five years. He said this will save 10MW.
“The intention is for NamPower to encourage the exchange of electric heaters by providing a rebate of 10% on the installation cost for each heater that is replaced by a solar heater,” he said.
The campaign is to be implemented with collaboration with the local banking fraternity as well as the Solar Revolving Fund under the Ministry of Mines and Energy and the newly established Environmental Investment Fund.
Shilamba said NamPower was also in negotiations with large customers for access to their standby diesel generators to support electricity demand during peak and emergency periods. The programme is expected to save 110 MW over a period of five years.
Commenting on the current drought situation Shilamba said output at Ruacana Hydro Power Station has been reduced by 10% from 242 cubic metres per second in January 2012 to 181 cubic metres per second in January this year.
The situation worsened with water flow declining by more than 30%. The water flow at Ruacana is currently in the region of 60 cubic metres per second, compared to the 70 cubic metres per second required to operate one machine and 280 cubic metres per second that will be required to operate the whole power station at full load, he said.
Shilamba said negotiations are currently at an advanced stage for the import of additional 100MW from Zesco of Zambia, 100MW from EDM (Mozambique) and 50MW from Zesa of Zimbabwe.
Shilamba also said considerable progress has been made regarding negotiations with regional takers for the 400MW of the Kudu gas project that cannot be consumed in Namibia.
“Negotiations with the South African Department of Energy as the procurer and Eskom as the buyer are ongoing. Negotiations with CEC from Zambia for the Joint Development Agreement (JDA) have been concluded and will be signed in due course. CEC has expressed interest to off take up to 300MW from the Kudu Power Station through a PPA with NamPower. In addition to the off take, CEC is also keen to take up minority equity shareholding in Kudu Power,” he said.
