Up one level
A collection of the articles and papers of STS Users.
User Group Library Integrating Electricity Prepayment Systems into the REDS Environment
An article by Kobus van den Berg of Centlec published in the December 2005 issue of Energize Magazine. From an electricity distribution point of view, prepayment is an essential methodology to ensure successful electricity provision to customers in the South African context. This paper will try to highlight some of the issues at stake.
User Group Library Prepayment Installations
This paper challenges the basic assumptions surrounding electricity meter costs and complexities. It motivates a new category of meter referred to as an “Electricity Supply Unit” and describes an enhanced, universal mounting system for industry standard meters. It also introduces a novel, cost effective revenue management method using a feedback token that totally obviates the need for split or remote meter technologies - in a manner aligned with global vending trends1 and relevant to rural communities. By Roland Hill, Circuit Breaker Industries (Pty)Ltd.
User Group Library Globalisation of Prepayment
This paper explores the anticipated evolution of pre-payment meter technologies in a dynamic, global, wireless world. It attempts to project a vision of an emerging on-line pre-payment electricity service and seeks to highlight the technical and organisational challenges to be addressed if the STS technologies are to become a global standard. By Roland Hill, Circuit Breaker Industries (Pty)Ltd.
User Group Library Prepayment Meter Audit
By Roland Hill, Circuit Breaker Industries (Pty) Ltd. This paper motivates the need for efficient auditing procedures and recommends an augmented meter reading method. Common data transfer standards are described and the importance of SARPA’s leadership role is stressed. Items worthy of standardisation are raised and implementation concerns noted. The benefits of installing check meters are mentioned.
User Group Library Prepayment Property and Wealth Tariffs
By Roland Hill, Circuit Breaker Industries (Pty) Ltd. This paper introduces and motivates the innovative tariff features provided by the STS- 2000 specification. Its compatibility with single, two part and step tariff usage in Africa, is demonstrated. Methods of fairly and transparently applying such wealth tariffs upon affluent consumers, to cross subsidize indigent consumers supported with poverty tariffs, are presented. A summary of the STS token definitions is given and the activities of the STS Association are mentioned. Future STS proposals are noted.
