A smart energy network is a total energy network system consisting of an electricity grid, a natural gas infrastructure, a district heating network and advanced information and communications technology. A Smart Energy Network (SEN) can improve reliability, security, and efficiency of energy systems by enabling an optimal combination of renewable energy, energy storage, and effective natural gas energy applications, coupled with conventional bulk supply of energy; integration is achieved with advanced information and communication technologies. A SEN has the potential to address Ontario's challenges in energy security, global climate change, renewable energy integration, and growing energy demand.
