Larger integration of Wind and Solar Power into the Grid is possible according to NREL study

I was fortunate to attend a recent International workshop on "Smart Grid and Renewables", organised by the Power & Energy Society of the IEEE, Bangalore Chapter, held at the beautiful Infosys Campus. There were lot of questions and discussions about the impact of pumping more Renewable Energy into the existing Grid. It was a tough time for the Smart Grid Experts from the U.S to answer the questions raised by the Engineers from the Indian utility companies. Engineers from the Indian Utility companies were sceptical about the consequences of mixing more RE power into the Indian Grid because of their experience in Tamilnadu (A southern Indian State where the Wind Generation is substantial) I hope that this study by the National Renewable Energy Labarotary (NREL) will be beneficial for the Smart Grid Researchers and technologists who wants to inject more Renewable Power into the Grid. N.R.E.L recently released an intial study assessing the operational impacts and economics of increased contributions from wind and solar energy producers on the power grid. The Western Wind and Solar Integration Study examines the benefits and challenges of integrating enough wind and solar energy capacity into the grid to produce 35 percent of its electricity by 2017. The study finds that this target is technically feasible and does not necessitate extensive additional infrastructure, but does require key changes to current operational practice. The results offer a first look at the issue of adding significant amount of variable renewable energy into the grid and will help utilities across the region plan how to ramp up their production of renewable energy as they incorporate more wind and solar energy plants into the power grid.

“If key changes can be made to standard operating procedures, our research shows that large amounts of wind and solar can be incorporated onto the grid without a lot of backup generation,” said Dr. Debra Lew, NREL project manager for the study. “When you coordinate the operations between utilities across a large geographic area, you decrease the effect of the variability of wind and solar energy sources, mitigating the unpredictability of Mother Nature.”

The study focuses on the operational impacts of wind, photovoltaics, and concentrating solar power on the power system operated by the WestConnect group of utilities in the mountain and southwest states of the United States of America. Though wind and solar output vary over time, the technical analysis performed in this study shows that it is operationally possible to accommodate 30 percent wind and 5 percent solar energy penetration. To accomplish such an increase, utilities will have to substantially increase their coordination of operations over wider geographic areas and schedule their generation deliveries, or sales, on a more frequent basis. Currently generators provide a schedule for a specific amount of power they will provide in the next hour. More frequent scheduling would allow generators to adjust that amount of power based on changes in system conditions such as increases or decreases in wind or solar generation.

The study also finds that if utilities generate 27 percent of their electricity from wind and solar energy across the Western Interconnection grid, it would lower carbon emissions by 25 to 45 percent, depending on the future price of natural gas. It would also decrease fuel and emissions costs by 40 percent.

Other key findings from the study include:

•Existing transmission capacity can be more fully utilized to reduce the amount of new transmission that needs to be built.

•To facilitate the integration of wind and solar energy, coordinating the operations of utilities can provide substantial savings by reducing the need for additional back-up generation, such as natural gas-burning plants.


•Use of wind and solar forecasts in utility operations to predict when and where it will be windy and sunny is essential for cost-effectively integrating these renewable energy sources.


The study was undertaken by a team of wind, solar and power systems experts across both the private and public sectors. The study complements the recently released Eastern Wind Integration and Transmission Study, which examines the feasibility of integrating up to 30 percent wind in the eastern states.

The report released today is an important first step in assessing the impact of solar and wind energy on the electrical grid. Under the American Recovery and Reinvestment Act, the Department of Energy is investing more than $26 million to further study the Western transmission interconnection, which will help states, utilities, and grid operators prepare for future growth in energy demand, renewable energy resources, and Smart Grid technologies.

Scott Waring described the stone cheap nike jordan shoes anomaly as a “Face on Mars.” NASA had pointed Cheap Nike jordan shoes out the apparent head statue along with other stone anomalies with cheap jordan different color arrows. This helped bring it to Waring’s attention, wholesale jordan shoes for sale who cheap jordans claims that the head was likely part of a larger cheap jordans statue that discount nike jordans was broken apart during some air jordan shoes past cataclysmic event. The clarity of the head and face is wholesale jordan shoes stunning. This makes it difficult to dismiss Waring’s conclusion Cheap jordans that the wholesale jordan shoes photo is powerful evidence of a jordan shoes for cheap past cheap jordan shoes civilization on Mars.
