Energy Management

Sustainable Energy Management includes three key components: price optimization, usage optimization and generation optimization. An awareness of the energy balance and prediction of consumption and production require an energy management system and a savings program. Energy management constitutes optimization of all the components to order to achieve the goal of ensuring a continuous supply of energy resources and water in the short and long range, in the quantity, availability and quality required, at an optimal economic and environmental cost, while ensuring the strategic security of the infrastructure.

The Internet of Things: A System That Pays You to Reduce Your Electricity Use PDF Print E-mail
Written by Rod Kirk   

ohm connect logo

The speaker will present a primer on smart grid demand-response and a demo of Ohmconnect.  OhmConnect is a Demand/Response web-based application that allows many people to pool their response to fluctuations in demand on the grid.  OhmConnect sells "load reductions" to the Independent System Operator by having consumers of power reduce their demand at certain times when power is expensive to produce.  Some of this is automated – Internet-connected devices in the home can be directly controlled to reduce demand.  Some is manual: a Text message or email to users prompts them to turn off some load – defer laundry, turn off lights, etc.  Participants are paid for their contribution to the aggregate reduction that can be sold to the grid, as measured by their smartmeter vs. historical use pattern.
