Making the business case for the smart grid is an important utility goal. It provides the justification for making or deferring required investments. Utilities might find it necessary to engage in a cycle of continuous strategic planning.

As electric vehicles become commonplace, will the grid be able to handle the extra load? Too many cars plugging in at once might cause disruptions and necessitate costly infrastructure upgrades. Handling the vehicle load in a smart way, however, will ensure a smooth transition to the plug-in future.

Advancements in forecasting have improved the reliability of day-ahead and hour-ahead estimates of wind generation. Wind never will behave like a base-load power plant. But as system operators integrate wind forecasts into their planning and market processes, they’re transforming intermittent wind energy into a variable but reliable resource.

Small modular reactors (SMRs) are nuclear generating units that are about the size of railroad cars and provide about one-tenth to one-fourth the power of full-size reactors. As a result, they cost a fraction of what full-size reactors cost. The reactors are designed to provide between 40 MW and 300 MW of electric power, compared with the 1,100 to 1,700 MW output of larger reactors. In addition, most are expected to cost under $1 billion, compared with the $5 billion to $10 billion price tags of the larger units.

Will CO₂ reductions and investments in non-emitting resources lead to rising costs and economic malaise? Not if America ramps up natural gas generation and turns down coal generation to achieve CO₂ reductions of 14 to 20 percent.

Siemens Energy has been awarded an 18-month, $300,000 R&D program by the Illinois Clean Coal Institute to study the effects of coal and coal-derived syngas combustion on the behavior of material and coating degradation in utility boiler and gas turbine environments. Focus areas of the research program will explore materials degradation modes in integrated gasification combined-cycle (IGCC) systems and utility boilers.

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.

Utilities are using automation and back-office systems to improve their performance on outage management and service restoration. The next generation of smart-grid technologies promises a revolution in self-healing systems. But first the industry must gain confidence in the technology—and the business case for investment.

Six weeks ago, FERC opened a notice of inquiry to invite industry comments on whether wind, solar, and other intermittent energy sources face unfair obstacles in wholesale power markets. Now assigned their own acronym—VERs, for “variable energy resources”—renewables make up a growing percentage of the nation’s energy supply portfolio. But as FERC notes, they present “unique challenges,” especially in terms of constraints on location and limits on the degree to which system operators can control or dispatch individual VER units. Thus, FERC suggests that certain common rules and practices, such as those for unit commitment, dispatch, and scheduling, might make it overly difficult to integrate VERs into the grid.

Opinion polls show that Americans are growing tired of eco-nannyism. This isn’t a new trend, but on February 7 it went prime-time, during the biggest TV event of the year: Superbowl XLIV.
