1. Energy metering

  • We do metering installation of pre-paid, conventional and programmable meters either check meters or sub-meters.
  • We do meter audits to ensure accurate electricity revenue management.
  • We do meter programming and downloading for audit and office purposes (profile, billing data, stored history and energy consumption).
  • We also install current and voltage transformers (CT/VT).

2. Sub metering

  • We supply and install sub meters.
  • We do sub meter readings and prepare invoices for billing.

3. Revenue Recovery

  • We investigate the customer’s Municipality/ Eskom/ City Power account from inception to check if:
    • The customer is billed on the correct tariff
    • The customer is billed on the correct meter
    • The account is based on actual readings
    • The meter is correctly programmed according to actual CT ratio.
  • If found that there is credit due to the customer, we shall pursue the passing of the credit with the relevant electricity supplier.
  • We install check meters to ensure our customer is billed on accurate readings.

4. Power factor improvement

  • We install power factor correction devices for:
    • The reduction of electricity costs
    • The reduction in current therefore less wear and tear on switch gear
    • The reduction in electricity charges
  • Full 24 Month Guarantee on the whole installation.
  • Power Factor Board pays for itself in ± 8 – 10 Months, Giving you ± 180 % Return on your investment over the 24 month period.
  • All our products are environmentally friendly with no oil impregnation and no harmful effects to the Eco-system.

5. Energy balancing

  • We assist in ensuring that the load is equally distributed in all phases to minimize the overload.

6. Disconnections & reconnections

  • Disconnections/ reconnections of electricity supply.
  • Level 3 disconnections (removal of the meter

7. Billing services

  • We advice customers on appropriate tariffs that are being provided by the electricity utility.
  • We provide a solution on sub-metering billing.

8. Prepaid metering

  • Installation of prepaid meters
  • Conversion from conventional to prepaid meter
  • Sub metering using prepaid meters

9. Automated meter reading ‘e-metering’

Unique features of E-metering

‘e- metering’ is a unique internet hosted metering and billing system, which is fully owned by Emerald Metering & Utility Management. Emerald operates as a multi-disciplined team of electrical engineers, software engineers, data analysts and technicians who have extensive experience in energy metering, communications, analysis and energy metering systems. The company's sole focus is energy metering and specializes in developing and providing innovative metering system solutions for utilities, commercial and industrial customers.

The information age has been attained where the Internet is no longer a curiosity for academia, but is becoming an essential business tool. E-metering has been a natural progression in the development of metering data acquisition products and has been successfully implemented in a number of municipal, commercial and industrial applications around the country.

The system is efficient, accurate, and accessible to all consumers across the spectrum and delivers information technology solutions that de - mystifies energy decisions and transforms the way energy providers and consumers manage energy. No special software is required to access information – all that is required is a standard Internet browser package such as Internet Explorer or Netscape. Little or no training is required, as anyone capable of browsing on the Internet will immediately be comfortable with the user interface. Installation is quick and cost effective, with existing infrastructure (meters) capable of being upgraded, certified and modems attached to enable instantaneous communication. In certain municipalities existing meters have communication capability and can be immediately communicated with.

Using their Web browser, users can view load profiles, usage history charts, and a variety of statistics using load and billing data from multiple facilities. E-metering also offers municipalities the ability to use any number of different tariffs, of any complexity, with changes to tariffs being accomplished through a change to the single tariff module in real time. It gives users the ability to generate bills and estimate bills in the same format as their monthly statement, even before the billing period has ended. Data can also be downloaded for further analysis in a spreadsheet application such as Microsoft Excel.

Both energy providers such as utilities or electricity resellers and commercial or industrial large power users will benefit from E-metering. In remote metering systems there are essentially two scenarios: high density applications where a large number of metering points are situated in a small geographical area (such as a large shopping mall for example) or low density applications where metering points are located over a wide area (such as large industrial sites for example). Both systems present different challenges and problems with respect to data acquisition, communication and data processing. E-metering is unique in that it provides a single solution to both types of installation and in fact an installation may consist of a mixture of these two types.

Users are provided with the tools for advanced billing, load data validation and estimation, energy usage and pricing analysis, and a variety of value-added online energy information services.

One of the major benefits of E-metering to utilities and electricity re-sellers is that it allows them to strengthen customer relationships, but in addition the system also enables the following:

  • Provision of accurate bills for customers or tenants
  • Provision of a tool to ensure the integrity of the metering system through remote testing of meters
  • Curtailment of administration functions
  • Customer research
  • Competitive assessment applications
  • Load research

Commercial and industrial Large Power Users purchase their electricity from a utility or electricity re-seller and in the overwhelming majority of cases, pay accounts generated from manual meter readings. Basically, the financial value of electricity consumed appears as a single number at the bottom of a Utility account. In many cases the applicable tariff may be a complex one based on time of use and these billing systems simply do not provide the users with sufficient information to effectively manage their electricity consumption. E-metering forms an essential tool for municipalities to accurately calculate the impact of a new tariff and to formulate consumption strategies for maximising savings realised as a result.

Energy meters have in recent times become increasingly sophisticated electronic instruments and are able to record and store the half hourly consumption patterns. The problem is that this information requires specialised software to utilise and interpret the information in a meaningful way, and is therefore is out of the technical capability of most municipal staff, save specialized personnel in electricity departments.

Further to this, the consumer is unable to relate the electrical consumption in units to financial terms making it extremely difficult to implement meaningful internal electricity efficiency programs. In other words, from the perspective of a consumer, the output that needs to be managed is money and not units.

In low-density applications, the system is interfaced to modern electronic multifunction meters directly. The communication protocol of the meter is used to extract the register and profile information via the GSM network. This data is validated and placed into the relational database.

The end-users have access to this “up to the minute” information, which empowers them to make decisions on their own energy consumption patterns and implement energy management measures and cost allocations that have previously been difficult or even impossible to make due to a lack of accurate information. For example, it is now be possible for each consumer to examine their own pattern of energy consumption and to devise simple measures to modify these consumption patterns in such a way that significant savings to the electricity bill is realised all this done with the computer in their offices at a time convenient to them!

Further benefits to the end user include:

  • The ability of a user to centrally analyse their own metered interval load data using and billing information for multiple locations
  • Measure the effectiveness of various energy efficiency efforts
  • Download energy usage data for further in-house analysis
  • Identify anomalies in energy use
  • Improve operational efficiency
  • Reduce energy costs
