How DG and microgrids change the game for utilities.
Energy microgrids have emerged as more than just a curiosity. The technology is improving, costs are falling, and developers are lining up to build projects. How will microgrids overcome the substantial challenges that stand in their way?
The rationale for microgrids.
Edward N. Krapels and Clarke Bruno
Despite an array of challenges, microgrids are becoming a force in the market. Innovative projects bring greater efficiency and resilience.
Protecting smart systems against cyber threats.
Smart grid technologies bring a host of cyber security considerations that need to be addressed throughout the T&D domain—and even into the customer’s home. In this exclusive report, Department of Energy authors team up with industry experts to examine how to deal with the changes and challenges of securing the smart grid.
Modeling the value of various technologies and applications.
Ahmad Faruqui, Peter Fox-Penner and Ryan Hledik
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.
Utilities hurry up and wait to apply for grant money.
The American Recovery and Restructuring Act (ARRA, or the Recovery Act), signed into law in February, provides $4.5 billion in stimulus funding for programs aimed at “electricity delivery and energy reliability activities to modernize the electric grid.” This funding commitment, and swirl of industry and lawmaker activities since, has helped lift the smart-grid agenda out of the shadows of utility engineering departments and into the public’s broader view.
What the U.S. electricity sector must do to significantly reduce CO2 emissions in coming decades.
Revis James, Richard Richels, Geoff Blanford, and Steve Gehl
The large-scale CO2 reductions envisioned to stabilize, and ultimately reverse, global atmospheric CO2 concentrations present major technical, economic, regulatory and policy challenges. Reconciling these challenges with continued growth in energy demand highlights the need for a diverse, economy-wide approach.
Is DER competitive with traditional utility investments, and if so, what are the costs and benefits?
Eugene L. Shlatz & Steven Tobias
Utilities must make hard tradeoffs regarding which distribution investments offer the greatest value. How should they quantify DER as integrated into the grid?
Innovation must play a key role in each company.
Clark W. Gellings and Steve Hoffman
An EPRI vice president cites areas of concern in each part of the electricity value chain. How can IOUs overcome the formidable difficulties ahead of them?
S. W. Hadley, T. K. Stovall
This final installment of Oak Ridge National Laboratory's series on distributed energy resources investigates efficiency, the environment, and generation displacement.
Distributed energy resources (DER) have been touted as a clean, efficient way to generate electricity at end-use sites, potentially allowing the exhaust heat to be put to good use as well.
T.K. Stovall, S.W. Hadley, and D.T. Rizy
In the first of three articles, experts at Oak Ridge National Laboratory examine the technical obstacles, deployment, and economic issues surrounding distributed generation.
The existing electric power delivery system is a critical part of this country's economic and societal infrastructure, and proposals to increase the role of distributed energy resources (DER) within this system are welcomed by few in the utility industry.
