In Southern Africa, Zimbabwean energy officials have stated that the installation of electric water heaters will no longer be allowed in newly developed properties but rather solar powered systems should be installed, Reuters reported.

This is expected to reduce the strain placed on the country’s power grid, which is currently challenged in meeting the increasing the demand.

Officials stated that existing geysers will be phased out within the next five years, with the hope of saving 400MW.

Zimbabwe: new regulations

According to Reuters, the state-owned Zimbabwe Electricity Distribution and Transmission Company (ZEDTC) said that government is targeting to publish new regulations by the end of this year.

Energy Minister Samuel Undenge said: “The country may achieve a power saving in the range of 300MW to 400MW, which in itself is a virtual power plant.

“Solar water heaters (will) become mandatory at every new house before connection to the grid.”

Smart meter systems

With efforts to increase efficient use of electricity, the ZEDTC issued a tender earlier this year seeking the procurement of 60,000 smart meters for medium and large power users.

Speaking to senior manager at ZESA Holdings Wilfred Shereni at the time, he noted that the smart meters will be targeted at customers with a capacity above 100Amps.

This is due to the current STS prepaid metering systems being restricted by technological limitations.

Shereni said: “The current prepaid meters are deployed at points with a capacity of 100Amps and below, which cannot implement demand metering as they are for energy metering only.

“Meters that are above 100Amps are billed for energy usage and demand and will require a meter that can measure and meter both attributes.”
