Lahore, Pakistan --- (METERING.COM) --- May 20, 2013 - MicroTech (www.mtilimited.com) was selected to implement the first of a kind implementation of AMI technology in Pakistan in a project awarded by Power Information Technology Company (PITC) and sponsored by USAID to monitor load and losses at grid and feeder level.

The solution was based on MicroTech’s fleet of advanced metering infrastructure solutions including metering and backend software system for deployment at all nine discos as well as the National Power Control Center (NPCC). The project was designed to eliminate incidences of unscheduled load shedding by accurately assessing total load demand information on a near real time basis.

Pakistan has been suffering from acute power shortages that can go up to 6,000 MW in peak times of the year. In order to make the impact of load shedding less disruptive, the use of MicroTech’s product portfolio is instrumental. MTI’s metering products have been designed and tested to work in the strenuous conditions of Pakistan. The AMI products have the capability to communicate over the GSM network in a secure manner and can relay information between different elements of the grid network, including the control centers of the nine discos and NPCC.

Specialized AMI meters are installed on all incoming and outgoing feeders, which also provide information on breaker status and time interval data on system load. To elaborate, instantaneous load information on all AMI meters installed on feeders is relayed to each grid substation, and consolidated data emanating from all substation grids connected to a disco is then presented to the disco operator as a single total load value, while supporting the capability to view live screens for viewing instantaneous data on load, etc. at different points of the grid network. Furthermore, disco substation aggregated loads can be presented as the total grid load. The impact of transmission loss is also included in reports for better monitoring and planning. The disco control center operators also have the ability to drill down into the data for a particular grid substation and see the load on any 11 kV feeder with 5 and 15 minute interval data for incoming and outgoing feeders respectively.

All this greatly augments the capability of Water and Power Development Authority (WAPDA) to avoid unscheduled load shedding, schedule power generation better, and effectively plan load shedding events. Summarized information is provided to all the discos and the NPCC control center with details of actual load of all grid substations in each disco.

“We take pride in being selected to provide complete end-to-end technology solution for this project,” said MicroTech’s CEO, Mr. Saeed. “The collaboration with PITC and USAID for MTI’s AMI solutions exalts the importance of this technology for a country like Pakistan; because of this the electricity operator can now perform important load monitoring and planning functions in near real time, something that wasn’t possible before.”

MicroTech was engaged in the fulfillment of a contract for providing 10,190 AMI meters, and meter data collection system for all nine discos, including main and backup servers and three years’ maintenance and upgrade services.
