合同能源管理在过去的发展过程中一直面临着市场模式单一、市场规模散小、融资及税收成本较大、收益期限过长的发展瓶颈,难以适应我国节能减排工作和节能产业发展的需要。合同能源管理应当在模式创新以及法律规范性上进行更加深入地探索和研究,改变过去传统的BOT(建设—运行—转让)模式,尝试性将融资租赁模式、金融机构持股模式和专业融资担保模式运用到合同能源管理之中,同时完善能源管理合同,建立合同能源管理项目收益权融资交易制度,防范法律风险,最终实现合同能源管理的法定化。 相似文献

Since the Energy Policy Act of 1992, federal facilities have increasingly used performance contracting to finance energy and water efficiency measures. Utility Energy Performance Contracts (UESCs) have received less attention despite having similar goals and processes as Energy Savings Performance Contracts (ESPCs). This paper provides a comparison between the two performance contracting models and highlights the tradeoffs that should be considered. Higher costs observed in ESPCs are driven by higher overhead and the costs of savings guarantees. These cost drivers cascade into longer financing terms and higher interest rates. These results suggest that federal agencies should explore UESCs as a potentially more cost-effective way to achieve energy savings improvements. 相似文献

国际工程承包是世界经济交往和技术合作的一种重要方式,随着世界经济区域化和一体化双重趋势的持续发展,国际工程承包市场的开放程度日益提高,竞争日趋激烈。特别是我国加入WTO后,给对外承包事业带来了新一轮发展机遇,许多国内大型国际承包集团,越来越多地参与国际工程承包市场的竞标活动,直接面对世界知名的大承包集团的挑战,从而对我国的承包商的管理水平、工程承包经营水平和技术装备能力提出了更高的要求。针对目前国际工程承包市场的现状,阐述了我国大型承包公司和集团应该采取的发展战略和竞争策略、承包经营的方法、投标“三必须”、施工合作伙伴的选择、公共关系的建立等。 相似文献

High and growing shares of wind and solar generation can lead to economic retirements of controllable capacity, which creates the need for long-term resource adequacy mechanisms that compensate units needed to maintain system reliability. We use game-based simulation to compare two approaches for ensuring long-term resource adequacy: capacity markets and forward contracting. We also conduct “policy prototyping” of a specific implementation of forward contracting, Standardized Fixed-Price Forward Contracts (SFPFCs). SFPFCs are standardized forward energy products sold through a centralized procurement process in which 100% of expected demand is auctioned off several years ahead of energy delivery. SFPFCs retroactively adjust contract quantities in each covered hour according to that hour’s share of total demand in the compliance period. This encourages generating companies to manage the risk of higher-than-expected demand in any given hour. Our game runs suggest that forward contracting can yield significantly lower cost to load than capacity markets because it removes the incentive for gencos to exercise unilateral market power in the short-term energy market. The SFPFC implementation in our games effectively maintained system reliability and delivered moderate costs to consumers while maintaining financial viability for gencos. It did this even in scenarios with high carbon prices and high renewable shares incentivized by a Renewable Portfolio Standard (RPS) with tradable Renewable Energy Certificates (RECs). 相似文献

With the enactment in 2013 of a renewable energy scheme by contracting qualified power generation facilities working on renewable energy sources (RES), the process of construction and connection of such facilities to the Federal Grid Company has intensified in Russia. In 2013–2015, 93 projects of solar, wind, and small hydropower energy were selected on the basis of competitive bidding in the country with the purpose of subsequent support. Despite some technical and organizational problems and a time delay of some RES projects, in 2014–2015 five solar generating facilities with total capacity of 50 MW were commissioned, including 30 MW in Orenburg oblast. However, the proportion of successful projects is low and amounts to approximately 30% of the total number of announced projects. The purpose of this paper is to analyze the experience of implementation of renewable energy projects that passed through a competitive selection and gained the right to get a partial compensation for the construction and commissioning costs of RES generating facilities in the electric power wholesale market zone. The informational background for the study is corporate reports of project promoters, analytical and information materials of the Association NP Market Council, and legal documents for the development of renewable energy. The methodological base of the study is a theory of learning curves that assumes that cost savings in the production of high-tech products depends on the production growth rate (economy of scale) and gaining manufacturing experience (learning by doing). The study has identified factors that have a positive and a negative impact on the implementation of RES projects. Improvement of promotion measures in the renewable energy development in Russia corresponding to the current socio-economic situation is proposed. 相似文献
