  1. DEMAND RESPONSE • ___________________________ • OUR RESPONSE TO CRITICAL CHALLENGES Manaen Srigiri James Abhilash

  2. COMPANY Overview • The Company develops, and manufactures smart grid solutions for electricity, water and gas utilities. • The Company’s Advanced Meter Infrastructure (AMI) portfolio includes a data management system housed at utilities data centres, smart meters and concentrators, intelligent consumer monitoring solutions, as well as load limitation devices. • The Company also provides solutions for industrial users including sub-metering applications. • The Company is certified worldwide by KEMA. Applied for BIS too. • The Company is supported by a strong design group based in Israel as well as manufacturing facility in India & subsidiaries in South Africa, and Hong Kong.

  3. SYSTEM ELEMENTS Overview Key Elements • Under Frequency Load Management • Demand Response Using Smart Meters • Distribution Demand Automation

  4. ENERGY SUPPLY PROTECTION Overview Under-Frequency Meter Digital Output UTILITY WAN PLC/GPRS Rapid Response GPRS/LAN Built-in GPRS Communication Feeder/ Distribution Transformer PLC Concentrator PLC Central Office Software Smart Meters Din Rail APM Smart Meter

  6. SYSTEM ELEMENTS Under Frequency Meters • Overview • Special circuitry installed within three phase/HT/MV meters. • Installed on feeders, and distribution transformers.  • Continuously monitors frequencies and reacts with 70ms to frequency variations nearing full capacity by activating a digital output to connect or reconnect certain lines exceeding configurable value.  • Automatic reconnection after a configurable period if power consumption is within limits defined. • Customizable limits on individual or groups of consumers.  • Remote activation via communications of critical condition limits by automation or manual operation.  

  7. SYSTEM ELEMENTS Load Control Element • Installed in industrial and commercial customers where significant non-critical power usage justifies the cost. • Relay to isolate and disconnect non-critical machinery remotely. The machinery/appliances themselves do not need any smart nodes built–in. • Optional din-rail devices which communicate with the Meter to disconnect specific lines.

  8. SYSTEM ELEMENTS PowerCom Smart Meters • Imax - predefined setting protects the circuit breakers belonging to the utility. i.e. automatic disconnection above 100 amps. • Icritical – During critical status when transformer is supplying near maximum capacity, select customers are limited at varying power levels. i.e. automatic disconnection above 60 amps. • Certain category groups of customers may be defined as exempt from load limitations (frail/elderly and emergency services).

  9. LOAD MANAGEMENT Benefits Protect Assets Avoid massive energy pulses by staggering load shedding frequencies. Prevent transformer overload. Protect dist. transformers. Real-Time Customer Satisfaction Modifiable frequency disconnection levels - same consumers not always the first affected. Personalized pricing. Two-way reliable and low-cost communications. Modify configuration values remotely. Automation Grouping of Customers. User friendly software. Peak shaving & load shifting. Reduce infrastructure invest.
