Modeling the value of various technologies and applications.

As utilities announce new smart-grid programs, they need a strategic method for quantifying benefits. Analytical models generate baseline benefit estimates and reveal big-picture trends. Decision makers need the best resources available to mitigate risks in choosing a smart-grid strategy.
The intelligent grid cannot be achieved without energy storage.
Rick Nicholson and Nadav Enbar
While much has been written about the intelligent grid of late, little attention has been focused on the role of energy storage in achieving its expected benefits. Energy storage is an essential component of the intelligent grid. Energy storage provides greater grid integration of variable renewable energy resource output (e.g., wind, solar); improved system reliability via the provision of grid regulation services; and peak demand reductions and, in turn, deferred capital spending on new and upgraded transmission and distribution assets.
What does the current landscape look like for distributed energy resources (DER)? What applications and business models are being pursued by leading companies, and where can we expect to find DER in the next 10 years-in 2015?
ACCORDING TO ONE RECENT SURVEY, MORE THAN HALF THE U.S. population now lives in states with customer choice. Moreover, industry executives expect 20 to 50 percent of these customers to choose a new electricity supplier by year end. %n1%n
With changes expected in the way electricity is generated, delivered and sold, exerting pressure on prices, what does the future hold for energy storage technologies?
After all, restructuring efforts appear most active in the highest-cost states -- those with average electricity prices running above 7 cents per kilowatt-hour.
Until a few years ago, the concept of distributed or modular generation was largely academic. Recent developments in the electric power industry, however, have brought this once esoteric subject to the attention of utility executives as well as state and federal policymakers. Centralized, large-scale plans to use modular generators and demand-side management (DSM) to displace utility investments in bulk-power resources and high-voltage transmission projects is unrealistic.
