Nearly 100 000 houses in Harare and Bulawayo have looped connections that are not compatible with prepaid metering technology, making it difficult for Zesa to install new units on them.
The houses are found mostly in old suburbs such as Highfield, Mbare, Old Mabvuku, Epworth in Harare while Bulawayo has areas such as Makokoba, Mpopoma and Iminyela.
The looped connection is a system where many houses are connected to one bulk meter.
Power theft, according to Zesa officials, is also high in these suburbs.
Zesa spokesperson, Fullard Gwasira said outstanding installations premises were predominantly in old suburbs which have looped connections that are not compatible with the prepaid metering technology.
Zesa has installed 532 000 prepaid meters countrywide at a cost of $71 million since August 2012.
02/10/2014 08:11:46: Nyanga: Gvt develops cold feet on troubled ZBC report
Months after ordering a forensic audit into the goings on at ZBC government has developed cold feet and now claims he board has the sole mandate to act.
Information ministry permanent secretary George Charamba this week declined to comment on the progress made so far regarding the audit done by a private firm under the supervision of the Auditor General.
Charamba said they have since taken a position that parastatal boards should be the ones to comment on those issues and ZBC has a board so it is the one to talk to.
He said when the report was received from the Auditor General by the ministry they shared the contents with them and they are studying the contents and they are on-going deliberations internally which are not at liberty to be discussed now.
