Public-private collaboration to protect our infrastructure.
Smart grid technologies bring a host of cyber security considerations that need to be addressed throughout the transmission and distribution domain—and even into the customer’s home. In the second of two exclusive articles, Department of Energy authors team up with industry experts to provide a path forward for securing the smart grid.
Evolutionary directions for electric system architecture.
Merwin Brown, Lloyd Cibulka and Alexandra von Meier
How will the technology and policy changes now sweeping through the industry affect the architecture of the utility grid? Will America build an increasingly robust transmission infrastructure, or will we rely more on distribution intelligence and microgrids? Scholars at California’s Institute for Energy and Environment analyze various scenarios to predict the possible futures.
The smart grid and its biomorphic destiny.
Smart grid technology is bringing inanimate objects to life. In connecting nodes and equipping the system with distributed intelligence, the network is developing toward an environment that becomes quasi-biological over time. Such an organic system might defy deterministic ideas of planning and control.
Transforming DR and smart-grid policies into reality.
Regulatory policies are evolving to make demand response and smart-grid planning a reality across the country. Cooperation between federal and state lawmakers will allow local flexibility within a uniform national framework.
Realizing the benefits of a modernized system requires an integrated strategy.
The U.S. power market consistently has displayed cyclical characteristics of boom and bust over the last two decades. Today’s market environment has been directly and significantly impacted by the recent economic recession. Decreases in load growth, declining commodity prices, and lack of accessible financing have caused challenges for the industry.
Network intelligence yields green returns.
Fred Wellington and Forrest Small
A more sophisticated delivery network can yield “carbon value” via zero or low-emission generation, T&D efficiencies and innovative market strategies.
The PJM complaint and the rising cost of electric reliability.
Who says ratepayers must accept the traditional measure of electric reliability—a single one-hour outage every ten years? If shown the bill ahead of time, might they decide otherwise; that such luxury is no longer affordable? Consumers are making similar decisions about gasoline and mortgages. Why not electricity?
Rate caps have squelched competition in Pennsylvania.
The prolonged period of capped rates in Pennsylvania—years longer than in any other state—has produced some benefits and some drawbacks. On the plus side, due largely to the rate caps, electricity costs in the Commonwealth have fallen from 15 percent above the national average in 1996 to below the national average in 2007. This has been a significant benefit, but a temporary one that many have taken for granted.
A comprehensive DR business case quantifies a full range of concurrent benefits.
The benefits of DR remain difficult to quantify. Building a comprehensive business case requires a shift in how policy makers think about DR in order to understand its real possibilities.
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.
