>>Supply and installation of smart meter and Utility Managements Platform for R̵̛͇̯͉̔̉͌͐̓̇͒͝e̶͙͆̒̍͘d̸̡̝͙͚̥̬̠̲͎̞̗̠̳̞̀ả̵̧͕̬̺̘̹͓̦̼͚̦̜̣̊͆c̶̣̰͉̜̙̪̞̏̃̓̈́̔͋͠ͅţ̷̯̤̩̠͐́̂͑́̽̒́̒͒̋̚̕͝e̷̤̻͙͈̦͉̻͍̖̭͓̳̔̾̇̕d̴̡̨̍̋̌͒̍͐ Local municipality. Please refer to the 'Summary' tab for reference data
PNPSCADA does not supply this service. PNPSCADA only supplies the software side. It is up to you to employ trained Technicians that can maintain the installations on site.
>>Service provider must conduct site inspection in order to confirm the data provided by the Client. The data provided  (specifications and quantities) by the client is for reference only
same as point 1
>>The smart meters must be safe, accurate and reliable. They must allow for multi-tariff abilities, remote updates, remote connect and reconnect and load factor monitoring
The way PNPSCADA does multiple tariffs, the tariff can be done either server side or meter side, so it is not always needed that the meter can handle multiple tariffsFor remote updates there is TCP Bridge, which allows you to connect to the meter remotely using the OEM Software.Not sure what is meant with remote connect and reconnect, but since it is CT meters it can't be 'breaker switching', right? In the event that it is breaker switching, that would also add 1 channel per meter.
Not sure what is meant with load factor monitoring, although the PNPSCADA Profile Graph does already show load factor. But, in the event that they want realtime load factor monitoring, that would be 1 channel per meter extra.
>>The smart meter data management system must provide an end to end Revenue Management solution for electricity. It must use internet based metering technology for web based load data visualisation and analysis.
Situations where pnpscada has helped in this regard:
- Facilitate clear billing (e.g. the meter totals are written on the bill), where the customer can see their own profile graph etc., which leads to less queries by customers
- Events: Detect blown fuses, faulty meters, tamper and cover opening events early, so that it can be fixed early
- Detect when a 'vacant' property is using power, so the squatters / thieves can be stopped
- Facilitate energy balancing, which can be used to identify unaccounted for energy or inefficient equipment
- Where the meter supports it, can facilitate the reconciling of prepaid meter actual use with bought electricity vouchers.
>>The service provider must customise the reports according to client requirements.
PNPSCADA supplies many reports that you can download and edit in Excel.
Alternatively, we develop PNPSCADA, so we can develop personalized reports for a price.
>>The service provider must  ensure that the municipality is the owner of the system'
PNPSCADA itself is licensed.
However, we do have evergreen options. That is where the client can pay for the licenses once off, and use the system for that number of channels in the future.
If the client wants evergreen options, they have to have their own PNPSCADA server.
Many of our clients run on the TruServ Self Managed server option from Xneelo, although the client is welcome to host the server at their own premises.
There will also be a once off setup cost of the server.
The Auditor General is supposed to prevent Municipalities from getting into a situation where a Third Party (like PNPSCADA) can withhold data so that they cannot bill their clients. The evergreen licenses was specifically designed for this case. Although it is also available to non-municipalities. More information on the requirements for your own server can be found here: https://wiki.pnpscada.com/farticle.jsp?article=50
>>The service provider must offer training of client representative on the use of the system and all other related activities as well as access to the system and generation of customised reports.
We do offer training on how to add the Meter to the system, basic communication troubleshooting, adding tariffs, running bills and creating limited logins for End Users.
>>2. System Architecture
>>The system must be an advanced metering infrastructure (AMI) which comprises an integrated system of smart meters, communications networks, and data management systems that enable a two way communication between the service provider and customer
Yes
>>The on site hardware must comprise Smart meters, modem, GDSP sim card, GSM 3G antenna, boxes to house the meter (wehere applicable), correctly specified CT's, installation services and electrical installation materials.
same as point 1
>>The system must be able to accommodate additional sub-meters (smart) that will be installed in the future.
Yes
>>3. Drivers for effective utility management
>>The municipality need the system to have information available which will assist them in effective decision making such as
>>Proactive spend management (Cost vs budget)
>>Meter to bill validation (reconcilliation of utility bills to physical installations)
>>Tariff optimisation (review for most optimal tariff)There is a report to consider all applicable tariffs to a specific Meter Account and report on the top 2 Tariffs.
>>Real time electricity management (alerts based on pre-determined parameters such as maximum demand, power factor & cost thresholds
Not sure how realtime they need it to be. Typically we read the meters once per day, and then they can manage the alerts for the previous day.
Although there are also realtime screens to monitor demand, it is advisable that for Demand alerts it is better to not rely on an internet based system, but rather on Demand Notifiers and Demand Limiters.
>>Cost management (accurate internal and tenant billing)
Bills can be run against meter data
>>Reporting (customised management reports)
