Table of Contents



• This presentation leads into the topic of “Advanced Revenue: Large Power Users” in a

Smart Meter AMI Program

• It attempts to help with the question of how “prepayment” fits into modern Smart

Metering programs?

Questions that are typically asked are:

1. What the benefit of prepaid to the consumer, particularly the Bulk and LPU C&I

consumer?

2. How does a Utility introduce complex electricity tariffs into prepaid such as:

• Linear

• Tiered

• Max Demand

• Above linked to Time of Use (TOU) etc

Case Study:

3. Is the future direction of prepayment linked to the STS and split meter (“Thick”

meter), or by controlling “prepayment” in the AMI backend system with a “Thin”

meter?

4. What benefits come out of prepayment for both Utilities and Consumers?

5. How do “Water Meters” interface into the same framework as asked above?

This presentation explores these questions and provides some answers

Prepayment for Large | Medium Power Users (LPU | MPU)

LPU users can download and view online data in terms of real time

LPU consumer are able to plan according to real time data (e.g. when to

switch on their smelter etc)

Account reconciliation happens in a real time mode

No manual meter reading and inaccurate data

Tariff rating is done in real time and therefore they can determine their costs

despite the tariff codes being complex

Cash flow management – the customer can pay according to their cash flow

and consumption plan | Strategy, as well as optimise cost saving etc

Benefits of full Smart Metering AMI advanced revenue to the Utility |

Municipality

Benefits of AMI prepayment to Utilities | Municipalities are:-

Utility cash flow typically moves from 150 debtor days to minus 10 to 15

days

This means that the Utility gets cash in advance before electricity

consumption – thus allowing for growth planning and strategy.

Real time data is available to the Utility

Allows for planning, growth and value add support to the end consumer,

be it LPU’s | MPU’s or SPU’s

Grid control is enhanced as a real time view of load consumption and trends

is available.

Depending on the MDM, this type of data can be linked into a SCADA system

for grid control applications such as DRMS, Load Management etc

Benefits of full Smart Metering AMI advanced revenue to the Consumer

Benefits of AMI prepayment to the Consumer are:-

Improved cash flow – i.e. reduce debtor days?

Instant account and meter data visibility for the consumer – more consumer

centric control?

Ease of information and electricity payment: smart phone apps etc

Prepayment cash payments – link existing STS vending PoS to backend

system?



• Current STS prepayment tariff code structure is based on tiered | linear or static

pricing.

• Post payment tariffs were difficult to include in prepayment purchases as most of

these tariffs require post consumption calculations as well as timing calculations

Time of Use (TOU)

Max Demand

Energy Charge

Network Demand Charge

• A prepaid Smart Metering AMI system is able to incorporate many different tariff

codes and structures as the data we receive on a real time basis allows for intelligent

tariff rating.

• Also, a Smart Metering AMI system is able to offer more complex tariff structures

than even the post paid billing allows for! All tariffs in an AMI solution are done on a

real time basis and real time reconciliation.

Core Applications of the Solution

EnergyIP®

EnergyIP Prepay

Head End System – AMM+ / UDIS

Interfaces with meters to pull meter reads and events via secured connection. It also

triggers additional services like remote (dis)connections. AMM+ / UDIS stores raw data in

DB and pushes structured data to IEC adapter.

Meter Data Management System – MDM

Processes and analysis meter reads and events. It matches customer data with meter

data. After processing it forwards reads and event data to PPES via DTS (Data Transfer

Service).

PrePayment Energy System – PPES

Applies different tariff structures to consumption data and performs rating of consumption

data. It automatically triggers remote disconnect / reconnects as required via head-end

system. Provides customer usage and payment portal and performs customer wallet

deductions and recharges.




Smart Meters open a new era even where Prepaid Energy is already adopted

Balance | Wallet is managed locally at the pre-payment (STS) meter

Cost, complexity and reliability of pre-payment meters

Physical tokens (smart cards/keys) are required to transfer payment

Specific physical pre-payment meter needed

High NTL – no remote data access – manual access

No complex tariff codes – STS meter determines type of tariff rating

Traditional Prepaid Metering

Balance controlling is done in the back-office

Support of different payment methods, tariffs & incentives

Easy support both LPU’s and SPU’s – Remote disconnect | reconnect

Easier consumer access through a variety of channels to account and status

information

e.g. balance alerts, recharge & transaction history, consumption graphs

Remote change from postpaid mode to prepayment, no field activities needed

Reduced NTL | improved cash flow | security of revenue

Prepayment with Smart Meters




The key benefits of transforming to a digital smart meter solution

Key benefits for end consumers Almost real-time reads instead of once a month Improve your electricity usage and see direct improvement Maintain your balance and spending wherever you are (manage your own cash flow) Transparency of charging (correctness)

Closer interaction, get feedback on the grid and on your usage

Key benefits for utilities Demand management / Load management Revenue protection (non technical losses) Full cash flow positive – reduce debtor days to minus – i.e. total upfront cash flow Transparency of grid stability / faults Improved operational costs

Improved customer satisfaction



• Typically in a utility, Water and Gas departments are very separate and no

interoperations between them are found from a billing perspective.

• Each department duplicates each other forcing high cost budgets such as:

field service engineers

support personnel

separate systems

separate billing

admin staff etc.

• One of the most pressing issues to a utility or municipality is revenue collection and

profitability.

Electricity revenue is very important to both a utility and municipality as budget

allocation is very high.

In a water department, there are high costs with, normally, large revenue losses

and no profitability.

• Combining Electricity | Water and Gas Meters onto one system allows for:

Instant view of all the meters with one end user portal login.

Instant account and meter data visibility for the consumer – more consumer

centric control?

Ease of information and electricity payment using smart phone apps etc.

Improved cash flow – i.e. reduce debtor days?

Combined “Central Wallet” allows for easy revenue collection and security of

revenue

Conclusion…….

Co

lus

ion

With the growing acceptance of Smart Metering to provide real time big data, and

with Utilities in developing countries requiring a solution that caters for “security of

revenue”, the effectiveness of a well managed and run Smart Meter AMI

deployment needs to include the manageability of advanced payment (prepaid)

that enhances cash flow and profitability, reduces NTL, and adds huge value to

both the end user and utility itself.

Despite the huge capital expenditure (CAPEX) a Smart Metering AMI solution sets

back a Utility, in the long run it has far reaching benefits and features that justifies

the project. Return of investment can be easily justified for any Utiltiy

CAPEX can also be avoided in setting up and operating a Smart Meter AMI

Advanced Revenue Payment deployment by opting for an OPEX solution –

typically this is referred to as “AMI in the Cloud” or “Smart Metering as a Service”

(SMaaS) solution.

SSmart Metering as a Service - SMaaS

The biggest benefit of a SMaaS solution is OPEX vs CAPEX cash flow spend.

Yes, the arguments by many Utilities are: “where is the data kept and also the

security of their data”. These questions and concerns can be answered easily, but

the reassuring point is that a Utility can engage with a “SMaaS” deployment at a

low base, i.e. they pay on a “meter-per-month” basis as and when they install a

smart meter. Later on they can invest in an “on-premise” solution.

Siemens South Africa is a global specialist for both on premise and “cloud” Smart

Meter AMI Advanced Revenue Payment deployments. We would love to share

more on our solution for those that are interested. Please visit our stand in the front

to discuss and view a basic demonstration.
