Consumer Energy Efficiency AMI Solution
Business Outline
❖ In addition to the trend of using “New and renewable energy source development” in modern days, we are now being challenged on the basis of “World Climate Summit” in Paris, 2015 for issues with reduction of CO2. These trends are now affecting the industries in Korea to adapt DR system to reduce the energy spend.
However, apartment type houses and buildings where more than 10 million people reside have no or very limited way to save the electric fare except newly built ones. Of course, the transparency of its controllability is questionable. Therefore, this AMI system will enable to control the total spend of electric in most efficient way and promise the customer with minimum cost for control.
❖ DR (Demanded Response) Business
This business is focused on energy spend control for national wise when it hits its peak level. National electric power company makes contract with companies and factories who wishes to adapt energy saving control system, when the total amount of energy spend in nation reaches its threshold then contracted companies and factories automatically shut down the power spend in order to reduce the level. The supported amount of energy by shutting down will be paid-back as an incentive offer.
Strong Point
❖ In equipment wise, the analog meters will be switched to digitals with PLC, DCU equipments in order to deliver detail information of electricity used amount and its cost, estimated cost for power usage and etc. to the customer in real time.
❖ The system will give daily/weekly/monthly usage pattern including progressive usage information to the customer so as to recognize the most efficient way to reduce electric spend.
❖ Delivered information will allow the customer to identify when the electric has been used mostly and to set future plans for optimization in usage, we expect that at least 10% reduction can be achieved.

DR (Demand Response) System
Business Outline
DR (Demand Response) is a change in the power consumption of an electric utility customer to better match the demand for power with the supply. In DR, voluntary rationing is accomplished by price incentives-offering lower net unit pricing in exchange for reduced power consumption in peak periods. With own system, IENER_ADR, complying with OpenADR 2.0b specifications, ENERNET successfully adopt the system for DR service meeting international standard of OpenADR-based DR management. The system recruit companies and factories that want to reduce total use of electricity for energy peak management at the government level. Then they could cut down amount of electricity used by themselves in case of increasing demand for power and grant incentive for operation cost of electricity generation.
Strong Point
❖ OpenADR 2.0b
