This book was released on 2016 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, hydropower is the largest renewable energy source. However, as it is strongly climate dependent, the current climate change is altering the generating conditions. The watershed of the Sacramento River in California houses the greatest concentration of hydropower plants in all of the United States. As such, it generates about 10 percent of all instate-produced electricity. This study examines the changes of climatic conditions within the watershed, as well as its effects on hydropower generation in this region. Changes — decrease in this case — in electricity supply can lead to an increase of electricity prices. It was found that the watershed’s significance in California’s electricity mix indeed decreased, though climate change is only one reason for this development. The other reason, next to the factual decrease in hydropower generation due to altered climatic conditions, is the large and rapid increase in solar and wind energy generating facilities. Despite the size and electricity generating capacity within the watershed, the change in climate and to it related change in hydropower generation did not have a significant effect on the state’s electricity prices.
Download or read book Climate Change in California written by Fredrich Kahrl and published by Univ of California Press. This book was released on 2012-09-01 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: California is synonymous with opportunity, prosperity, and natural beauty, but climate change will certainly influence the state’s future. Changes will affect the economy, natural resources, public health, agriculture, and the livelihoods of its residents. But how big is the risk? How will Californians adapt? What will it cost? This book is the first to ask and attempt to answer these and other questions so central to the long-term health of the state. While California is undeniably unique and diverse, the challenges it faces will be mirrored everywhere. This succinct and authoritative review of the latest evidence suggests feasible changes that can sustain prosperity, mitigate adverse impacts of climate change, and stimulate research and policy dialog across the globe. The authors argue that the sooner society recognizes the reality of climate change risk, the more effectively we can begin adaptation to limit costs to present and future generations. They show that climate risk presents a new opportunity for innovation, supporting aspirations for prosperity in a lower carbon, climate altered future where we can continue economic progress without endangering the environment and ourselves.

This book was released on 2015 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: California has the most extensive water supply systems in the country. California reservoirs, more than 1000 reservoirs, play a major role in meeting the state's water demand (ACWA, 2013). These reservoirs require careful planning and management in order to achieve the optimal balance between different demand sectors. Some of these reservoirs contribute to the state's power supply through different hydropower plants. Beside some hydraulic and design parameters, the amount of produced hydropower is determined by amount of released water and the available storage. The amount of released water from any reservoir is a function of many factors, such as: climate, precipitation and inflows, demands and environmental requirements downstream. This study examines the implication of Climate Change and Warming on Hydropower production in Sacramento River hydrological region. A simulation model of the study area is built using Water Elevation and Planning System (WEAP). Three main reservoirs for hydropower generation in the study area were included: Shasta Reservoir, Oroville Reservoir, and Folsom Reservoir. Snowpack in west upper slope of the Sierra Nevada Mountains plays a major role in the hydrology of Sacramento River basin. Studies, (Franco et al. 2011) and (Rheinheimer et al. 2014), have shown a possible increase in the California's air temperature from 1.5 oC to 6 oC, with an expected greater impact on the upper Sierra Nevada Mountains. To assess the impact of such possible increase in air temperature, three warming scenarios were developed. The historical climate data (1964-2014) was collected for each catchment. Then for future projections (2014-2064), three air temperature increase scenarios were developed. The scenarios are 0 oC (no change, for comparison), 2 oC, 4 oC and 6 oC. Air temperature was the only parameter changed, other parameters such as precipitation remained unchanged. The result obtained from the model shows that the increase in air temperature can yield a considerable change in hydropower production. Under 6 oC increase scenario, the reduction in the total hydropower supply over the 50 years (2015-2064) was 9.43% for Shasta, 6.76% Oroville, and 6.44% for Folsom reservoir.

This book was released on 2007 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The world is faced with considerable risk and uncertainty about climate change. Particular attention has been paid increasingly to hydropower generation in recent years because it is renewable energy. However, hydropower is among the most vulnerable industries to changes in global and regional climate. This paper aims to examine the possibility of applying a simple vector autoregressive model to forecast future hydrological series and evaluate the resulting impact on hydropower projects. Three projects are considered - in India, Sri Lanka, and Vietnam. The results are still tentative in terms of both methodology and implications; but the analysis shows that the calibrated dynamic forecasts of hydrological series are much different from the conventional reference points in the 90 percent dependable year. The paper also finds that hydrological discharges tend to increase with rainfall and decrease with temperature. The rainy season would likely have higher water levels, but in the lean season water resources would become even more limited. The amount of energy generated would be affected to a certain extent, but the project viability may not change so much. Comparing the three cases, it is suggested that having larger installed capacity and some storage capacity might be useful to accommodate future hydrological series and seasonality. A broader assessment will be called for at the project preparation stage.

Available in PDF, EPUB and Kindle. Book excerpt: Many challenges, including climate change, face the Nation¿s water managers. The Intergovernmental Panel on Climate Change (IPCC) has provided estimates of how climate may change, but more understanding of the processes driving the changes, the sequences of the changes, and the manifestation of these global changes at different scales could be beneficial. Since the changes will likely affect fundamental drivers of the hydrological cycle, climate change may have a large impact on water resources and water resources managers. The purpose of this interagency report is to explore strategies to improve water management by tracking, anticipating, and responding to climate change. Charts and tables.

Download or read book Climate Change Effects on High elevation Hydropower System in California written by Kaveh Madani Larijani and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The high-elevation hydropower system in California, composed of more than 150 hydropower plants and regulated by the Federal Energy Regulatory Commission (FERC), supplies 74 percent of in-state hydropower. The system has modest reservoir capacities and has been designed to take advantage of snowpack. The expected shift of runoff peak from spring to winter as a result of climate warming, resulting in snowpack reduction and earlier snowmelt, might have important effects on hydropower operations. Estimation of climate warming effects on such a large system by conventional simulation or optimization methods would be tedious and expensive. This dissertation presents a novel approach for modeling large hydropower systems. Conservation of energy and energy flows are used as the basis for modeling high-elevation high-head hydropower systems in California. The unusual energy basis for reservoir modeling allows for development of hydropower operations models to estimate large-scale system behavior without the expense and time needed to develop traditional streamflow and reservoir volume-based models in absence of storage and release capacity, penstock head, and efficiency information. An Energy-Based Hydropower Optimization Model (EBHOM) is developed to facilitate a practical climate change study based on the historical generation data high-elevation hydropower plants in California. Employing recent historical hourly energy prices, energy generation in California is explored for three climate warming scenarios (dry warming, wet warming, and warming-only) over 14 years, representing a range of hydrologic conditions. Currently, the high-elevation hydropower plants in California have to renew their FERC licenses. A method based on cooperative game theory is developed to explore FERC relicensing process, in which dam owners negotiate over the available instream water with other interest groups downstream. It is discussed how the lack of incentive for cooperation results in long delay in FERC relicensing in practice and argued how climate change may provide an incentive for cooperation among the parties to hasten the relicensing. An "adaptive FERC license" framework is proposed, to improve the performance and adaptability of the system to future changes with no cost to the FERC, in face of uncertainty about future hydrological and ecological conditions.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Southwestern United States has a greater vulnerability to climate change impacts on water security due to a reliance on snowmelt driven imported water. The State of California, which is the most populous and agriculturally productive in the United States, depends on an extensive artificial water storage and conveyance system primarily for irrigated agriculture, municipal and industrial supply and hydropower generation. Here we take an integrative high-resolution ensemble approach to examine near term climate change impacts on all imported and local sources of water supply to Southern California. While annual precipitation is projected to remain the same or slightly increase, rising temperatures result in a shift in precipitation type towards more rainfall, reducing cold season snowpack and earlier snowmelt. Associated with these hydrological changes are substantial increases in both dry and flood event frequency and intensity. On one hand, the greater probability of drought decreases imported water supply availability. On the other hand, earlier snowmelt and significantly stronger winter precipitation events pose increased flood risk requiring water releases from reservoirs for flood control, also potentially decreasing water availability. As a result, lack of timely local water resource expansion coupled with climate change projections and population increases may leave the area in extended periods of shortages.
