Barriers and breakthroughs to a smarter grid.
Technology is quickly making energy storage more economical and effective than ever before. But companies that wish to invest in storage capacity face a journey through a frustrating regulatory no-man’s land. Opening the gateway for storage to deliver smart grid benefits will require a more streamlined and coherent approach to regulating storage as utility infrastructure.
Smart solutions for distributed renewables.
The goal of implementing a distribution management system (DMS) is to upgrade isolated, hands-on grid management processes into an interconnected and automated platform. This technology is transforming the way utilities operate distribution networks, and setting the industry on a path toward seamless integration of distributed resources—both supply and demand.
Green energy mandates might overburden gas pipelines.
Market rules could evolve to compensate gas suppliers for pressurizing pipelines when needed on short notice. Enhanced ancillary services will require innovative strategies using line pack in interstate pipelines and stepped up communication among gas and electric market participants to preserve reliability objectives in gas and electric markets.
Manufacturers scale up for utility applications.
Photovoltaics technology is emerging as a generation alternative—both for centralized and distributed facilities. Solar industry executives say their companies are overcoming obstacles to large-scale implementation. With advances in design and manufacturing, the future looks bright for utility-scale solar power.
Opportunity for advancement or exercise in futility?
The power grid has been slow to embrace renewable energy sources. In order to allow renewable energy sources to evolve into a solution rather than a headache, new tools and processes will need to be developed to forecast and control renewable production capabilities.
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.
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.
A 10-year horizon: 2005 - 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.
