Hydropower is generated from three reservoirs in the United States Army Corps of Engineer's Savannah District. These reservoirs include J. Strom Thurmond, Richard B. Russell, and Hartwell. Currently, a contract in place specifies that certain amount of energy must be provided to the region. The contract for the hydropower was based upon the critical hydrologic year of 1981. Historically, this was the most severe drought on record and assumed to provide the lowest net inflows for the three reservoirs, thus providing an attainable or reliable energy amount for the system, which suggests a dependable energy yield.;Reevaluating the contract amount and the period of obligation for energy production could create more consistent energy costs and allow for a more flexible basin management strategy. The analysis of factors that effects the hydropower generation would also provide insight into hydropower forecasting and strategies. This will lead to an increased control on environmental influences and higher economic benefit from the entire watershed. All of these factors would result in a greater overall benefit to regional consumers.;Analysis of 25 years of operational data has shown that a 90% reliable yield is about 40% less than the current contract. Moreover, the weekly restraints on generation requirements are often set too high as the frequency of meeting the contact amount is barely 30% for most months. These inconsistencies result in a cost variation which affects the consumers. Statistical analysis of historic energy generation provides procedures to determine a reliable energy yield by observing generation amounts that occur within an acceptable amount of risk. The reliable amount of energy was found to be about 15,500 MWh, which is significantly less than the current contract.;Additional conclusions from this study found that visitation could have a much greater economic impact over hydropower generation. In addition, local inflow to the Hartwell basin exhibited the strongest correlation to the system hydropower generation. These conclusions will help with new management, operation, and forecasting strategies in the Savannah River Basin.

Russell和Hartwell。当前，已签订合同规定必须向该地区提供一定量的能源。水电合同基于1981年关键的水文年。从历史上看，这是有记录以来最严重的干旱，假定这三个水库的净流入量最低，从而为系统提供了可达到或可靠的能源量，这表明能源产量可靠。重新评估合同金额和能源生产义务期限可以产生更一致的能源成本，并允许采用更灵活的流域管理策略。对影响水力发电的因素的分析还将为水力发电的预测和策略提供见识。这将导致加强对环境影响的控制，并从整个流域中获得更高的经济利益。所有这些因素将为地区消费者带来更大的总体收益。对25年运营数据的分析表明，90％的可靠收益率比当前合同低40％。此外，由于大多数月份满足接触量的频率仅为30％，因此每周对发电量的限制通常设置得过高。这些不一致导致影响消费者的成本变化。历史能源发电量的统计分析提供了通过观察在可接受风险范围内发生的发电量来确定可靠能源发电量的程序。发现可靠的能源量约为15,500 MWh，这比当前的合同要少得多。该研究的其他结论表明，探视可能对水力发电产生更大的经济影响。此外，哈特韦尔盆地的局部流入与系统水力发电之间的相关性最强。这些结论将有助于萨凡纳河流域的新管理，运营和预测策略。
