Hurricane Sandy and the Great Blackout wreaked havoc upon the state of New York crippling infrastructure, homes and businesses. Out of the darkness, a novel project to innovate the electrical power grid, New York Prize, seeks to explore alternatives to traditional means of both power generation and distribution. The impacts and lessons learned from the competition have the potential to upend conventional technology, regulatory policies and the utility business model.

The landscape in the energy industry is changing. Conventional forms of power supply and delivery are currently being complemented and, at times, challenged by distributed energy resources (DERs). While DERs can potentially provide significant benefits to the grid, their inclusion also may pose challenges to the conventional transmission and distribution (T&D) systems operation and planning. Often these challenges are associated with renewable energy resources, particularly wind and solar. Unlike traditional forms of generation, these resources cannot be dispatched to achieve desired power generation.

In the 1970s installing residential photovoltaic (solar) was an expensive mess. Seldom did a solar array exceed one kilowatt (kW) in size and most were smaller than a single kilowatt. Through the 1990s solar arrays on residential structures stayed at one to two kilowatts, as cost and complexity kept installations low. Over the last decade the average size of solar arrays on residential structures has grown.

With Smart Grids, the generational changes aren’t generations of people, but generations of the technology. So, if we assume developing regions aren’t the early adopters for Smart Grids, what does their Smart Grid look like? The nuts and bolts, and even “modules” may be very similar, but the drivers, legacy network, regulations and business case are certainly very different. India is a relatively representative example of many developing regions and their experience with a Smart Grid.
