Green data center  Data center powering them from renewable resources (solar & wind power)  It offers less OPEX ,reduced carbon emission  When ever there is a shortfall of renewable energy at one data center virtual machines are migrated towards another data center which is capable of working on renewable energy  If surplus power is generated at the data center it can be sold to the grid 20
  21. 21. Research directions on “BEHIND THE METER”  “behind the meter “refers to renewable resources operated at data center facilities  On site renewable energy generation is costly so data centers can signup with local renewable energy generation Less carbon emission effect More cost effective technique  Contract to allow the data center to migrate their workloads to another data center that when there is excessive user demand 21

  • An overlapping of electrical and intelligence\telecommunications infrastructures… the energy internet.

    In thinking of the power delivery system of the future, we found it helpful to think of bringing together two distinctly different but highly inter-related infrastructures. The electrical infrastructure (i.e., the poles, towers and wires) that has been created over the last 100 years and the “intelligence” infrastructure (i.e., the communications networks, distributed computing and sensors). The Intelligence infrastructure enhances the operation and maintenance of the electrical infrastructure and adds new functionality to the electrical infrastructure.

    The electrical infrastructure is very mature (at least in North America and Europe) – that is the processes, tools, standards and fundamental technologies for the electrical infrastructure are well established. New technologies will enhance the electrical infrastructure – and many programs within EPRI are working to develop that technology.

    The “intelligence infrastructure” is much newer – and companies thinking of this as a tightly integrated (networked) infrastructure is very new. The methods, tools and standards for creating the intelligence infrastructure are only beginning to be created. Essentially, when it comes to the intelligence infrastructure, it’s the wild west – almost completely lawless.

    In looking at the intelligence infrastructure – we see that it isn’t limited by technology. There is an abundance of technology that has been developed by other industries. Many times, in fact, there is too much technology.

    Today, pieces of the intelligence are installed in an isolated, fragmented way. this approach will not create an intelligence Infrastructure

    For the vision of the vision of the power delivery system of the future to be achieved, the intelligence infrastructure needs to be as pervasive and integrated as the electrical infrastructure – incorporating generation, transmission, distribution, energy markets and the consumer.

    The integration of these two infrastructures is what we see creating the intelligent grid or IntelliGrid.
