Prepaid Electricity Presentation By Ariel dela Cruz President/CEO

Prepaid Success Drivers Sachets: small denominations Pervasive Point of Sales (aka sari-sari stores) – Healthy ecosystem (store owners must make reasonable profits) – Familiar SMS reloading process Low Cost of CPE

Types of Prepaid Retail Electricity Systems Token Based – Customers buy from a vending station and are given a numeric token to be keyed into the meter Reloadable Cards – Customers buy from a vending station using reloadable cards which are either inserted into the meter or swiped near the meter Online – Customers buy from retailers scratch cards or e-loads which can reload the system thru text similar to electronic loads of the telcos

Major ERC requirements for Prepaid Electricity Systems Mandates specific Information on the meter Loading in reasonably small increments Load available 24 hours DU advances the cost of the meter. Meter Cost recovery mechanism to be approved by ERC Prepaid system MUST implement lifeline rates. 2 years of record keeping

Meter Display Requirements Current Load Balance Time and date Previous 30 day KWHR consumption The number of days into the current 30 day period Current consumption into the period Low Load warning

Logical Choice Online – Connectivity Challenges: Circuit Switched Data (sunset protocol) GPRS/EDGE/3G (Shared Pipes, not fully provisioned in Provinces) No SLA Wireless Broadband (not fully provisioned) Wireless ATM connectivity shows us the way: – Symstream Data over GSM Voice Channel – Best in Class remote device management

Prepaid/postpaid/TOU AMR Capable meter

System Architecture

Near Real Time Online System (30 mins. Update) Loading via SMS – Makes use of existing Telco load retailer network – Balance inquiry via SMS Calculation of remaining load is at the back end server – Allows monthly rate changes – Accommodates lifeline rate calculations Can be used as Postpaid Meter read via AMR

TOU capable Tamper alarms Optional support for Google PowerMeter Symstream GSM technology for highest SLA communications connectivity

Advantages vs. Competition Customized to ERC requirements Uses Symstream GSM connectivity for highest reliability & security in wireless data communications Uses SMS top-up infrastructure Use of concentrators brings the cost of wireless airtime to a minimum
