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.
(November 2011) Hitachi Power Systems America wins contract from Westar Energy; City of Fort Collins selects Elster, Siemens Energy, eMeter and Tropos GridCom to provide systems for its AMI project; Energate to supply smart thermostats for Oklahoma Gas & Electric; Jackson Municipal Electric Department selects Survalent Technology for a new SCADA system; Eastern Nebraska Public Power District Consortium selects ABB to implement an advanced smart grid-based SCADA; plus announcements and contracts involving EnerSys, S&C Electric, Siemens and others.
Connecting vehicles to smart systems.
Electric vehicles (EV) are just getting started, with rapid growth ahead. Plug-in hybrids and other EVs could capture 20 percent of the U.S. auto market by 2030. When planning for future infrastructure and technology needs, utilities face difficult questions about how EVs will interact with the utility grid. A comprehensive approach to communicating and integrating vehicle information will allow utilities and drivers to make the most of smart electric transportation.
Burbank Water and Power selects Tropos Networks for smart grid project, Survalent Technology installs SCADA system for Pearl River Valley Electric Power Association, Gemma Power Systems signs contract with Bishop Hill Energy, American Superconductor selects subcontractors for the Tres Amigas SuperStation transmission hub in Clovis, N.M., and more ...
Similar desires, different approaches.
Smart grid is a global phenomenon, but different countries are taking different approaches—for different reasons. For instance, utilities in Europe are more focused on laying the foundation for distributed generation and microgrids, while the United States is more concerned about creating standards for interoperability and security. Understanding the differences can help decision makers deploy smart grid technology effectively and economically.
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.
The most economical energy savings might be found in grid efficiency.
Power delivery efficiency gains constitute a valuable utility asset that can offset or defer new generation and T&D investments. Enabling technologies, utility demonstration projects and supporting regulatory frameworks are needed to validate potential savings.
The changing architecture of demand response in America.
Ahmad Faruqui, Ryan Hledik and Sanem Sergici
Pilot projects are demonstrating the potential of smart metering and smart rates to make the most of supply and demand resources. But as empirical studies show, not all pricing designs are equally suited to every region.
Pre-approvals demand a new approach to managing risks and costs.
Kris R. Nielsen, Patricia D. Galloway and Charles W. Whitney
Proving the need for new infrastructure construction for energy purchases has become more complicated for utilities. State commissions reserve the right to revisit rate-base investments after the fact, even when they’ve been pre-approved.
Ocean thermal energy conversion offers a timely renewable alternative.
C.E. (Gene) Carpenter, Jr., et al.
23 million square miles of tropical oceans daily absorb solar radiation equal in heat content to about 250 billion barrels of oil. Ocean thermal energy conversion technologies convert this solar radiation into electrical power by exploiting the thermal gradient temperature differences between the surface and the depths. This enormous resource merits a closer look as policy makers consider alternative technologies for serving future energy demands.
