    Now is the time to plan for the integration of significant quantities of solar energy into the electricity grid. Although solar energy constitutes a very small portion of our energy system today, the size of the resource is enormous: The earth receives more energy from the sun in one hour than the global population uses in an entire year. In addition, the solar photovoltaic (PV) industry is growing very rapidly, sustaining an annual growth rate of more than 40% for the last decade. The combination of this rapid growth, falling costs, and a vast technical potential could make solar energy a serious contender for meeting our future energy needs. View full abstract»

  • Finding a bright spot

    The photovoltaic (PV) industry has been a steady bright spot through economic ups and downs, and the future is looking brighter than ever. PV deployment has grown rapidly - from 0.3 MW in the 1980s to an expected 3,000 MW by 2010. Fueled by technical, economic, environmental, and social drivers, the contribution of PV to the U.S. electricity supply mix will likely be several times that amount by 2020. PV power systems and the utility industry have had a 25-year courtship with many different types of engagement. Utilities participated in the first ground-mounted power plants and rooftop installations on residences, schools, airports, hospitals, and other public buildings. These projects included U.S. Department of Energy (DOE)-sponsored residential experiment stations in Maine, Florida, and New Mexico in the 1980s; early PV plants in California and throughout the Southwest; and grid connection, demonstrations, inverter and system testing, and related standards development. Electric service providers are well positioned to expand their engagement in deploying PV systems. Many have found themselves in a bright spot relative to solar business opportunities. However, most providers are still facing the decision of whether to modify traditional business models for active engagement or maintain a reactive stance relative to PV and grid integrations. In either case, R&D that will lead to a more flexible and interactive electric distribution system is needed. A near-term priority for individual utilities is to define the grid-interactive and grid-independent applications and markets that offer the greatest potential risks and rewards and to develop plans for addressing them. This is particularly important in areas with excellent solar resources, strong incentives,or both. And this may hold true across the country under current policy and market conditions.

    Wind, solar, and other renewable energy important part of any present-day energy the portion of energy they supply to the certainly be increasing over the next few Arguably, large-scale wind power has reached technological maturity, and with more than 100 GW of capacity ample experience exists on integrating wind systems. Solar technologies, on the other emerging, and substantial R&D investments are being made to achieve parity with retail electricity costs in the near future. As this happens, annual capacity additions of solar power will become significant. View full abstract»

    In the United States and around the world, interest in concentrating solar power (CSP) is growing rapidly and its use is increasing. This solar thermal technology can meet a significant share of our electricity demand. Yet, while CSP's market share rises, concerns about the potential impact of CSP-generated electricity on the stability and operation of the U.S. power grid might create barriers to its future expansion in America.

    Germany is the country with the largest installed PV capacity in the world. As a result, Germany needs to be one of the first countries to look at adequate network integration. To tackle the challenges of the power system with regard to high PV penetration in the future, incentive systems are already formed and prepared that go one step further with regard to system integration. Also, grid codes for grid connection to the distribution network are defined that require grid-supportive behavior from PV systems. Real network integration by providing ancillary services for system operation is the aim of these new measures in Germany. Integration studies with different perspectives are performed in Germany.

    The penetration of photovoltaic (PV) systems in Japan has been on the rise. Two factors have been promoting the increase: improved generation efficiency of PV modules and governmental subsidies for the initial cost of residential PV generation systems. As a result, the cumulative installed PV capacity has increased exponentially; however, the cumulative installed PV capacity by 2007 was only about 40% of the target for 2010 (4,820 MW). Reaching the target and promoting larger installation capacities in the future will require further installation in the residential sector and the construction of large-scale PV systems. The New Energy and Industrial Technology Development Organization (NEDO) of Japan has conducted several demonstration projects to investigate technological issues regarding the large penetration of PV generation systems and to develop new technologies for using PV generation systems effectively. One of NEDO's demonstration grid-connected PV projects is the Ohta Project, a cluster of PV systems in a residential development. Another is the Wakkanai Project, the largest central-station PV system in Japan. View full abstract»

  • The Keokuk story [history]

    From 1910 to 1913, construction was under way on a huge hydroelectric complex on the Mississippi River at Keokuk, Iowa. Located at the foot of the Des Moines Rapids, the project included a dam that was constructed from Keokuk to Hamilton, Illinois, on the eastern shore of the river. The power plant was separated from the western shore of the river by a navigation lock to permit barge and ship travel past the dam. Originally, all electric power generation at the site was at a frequency of 25 Hz, primarily due to the slow speed of the generators. The major portion of the station's output was transmitted to the city of St. Louis, Missouri, located about 140 miles to the south. As constructed, the station contained 15 10,000-hp turbines, each driving a 7.5-MW AC generator for a total station output of 112.5 MW. The Keokuk station is still in operation today, but it now generates 60-Hz power. The conversion from 25 Hz began in 1942, but was not completed until 2002. View full abstract»
