Interest in other energy storage technologies has been led by the New York Power Authority (NYPA) and the Electric Power Research’s Institute (EPRI). The former is the US’s largest state-owned public power utility and the latter is an international, non-profit company performing RD&D in the electricity sector for the interest of the general public. For […]

A plug-in hybrid medium-duty vehicle programme: a national programme co-ordinated by the EPRI to procure three hundred and seventy eight vehicles for fifty fleets in the US. A total of USD 45.4 million has been allocated in federal stimulus funds for the development of electric vehicles and their commercialisation. A solar assisted plug-in vehicle charging […]
In Mexico, institutional power is most heavily vested in the President and the federal agencies. According to Article 27 of the Constitution, the President is granted the power to regulate the extraction and use of the nation’s waters, to establish areas where water cannot be extracted and, through his designated agents, establish rules for issuance […]
Mexico’s climate varies, from arid regions in the northeast to tropical zones in the southeast. The annual distribution of rainfall is irregular, with almost 80% occurring between July and September and the country’s water resources are unevenly distributed, with 67% of surface water located in the southeastern part of the country with 24% of the […]
There are three generations of technology in the solar PV market. The 1st generation (Gen 1.0) uses poly silicon as feedstock and has been in existence for 50 years. Thick crystalline silicon cells and modules, which include single crystal and poly crystal, cast silicon and ribbon silicon, account for 82% of cells production. The 2nd […]
The installed base of solar PV reached 9,151 MW by the end of 2009 and the final figure for 2010 is expected to be 11,520 MW. We now note the development and potential development of a number of large scale installations, the most significant of which are the 54 MW project in Strasskirchen and 53 […]
Non-utility generation capacity in the US markets has increased substantially. Numerous electricity trading hubs and wholesale electricity markets that have developed across the country have grown from about 6% of total generation capacity in 1991 to almost 20% in 1999. Non-utility generators produce power mostly for wholesale markets and are in direct competition with traditional […]
From total regulation in 1970 the market has evolved into partial deregulation, with varying degrees of market opening at the different stages of the industrial process. This has happened in 3 stages; wellhead deregulation, pipeline reform and finally unbundling gas services. At the retail level, reforms and restructuring have occurred on a piecemeal basis. For […]
Reserves may be classified as proved if facilities to process and transport those reserves to market are operational at the time of the estimate or there is a reasonable expectation that such facilities will be installed. Reserves in undeveloped locations may be classified as proved undeveloped provided (1) the locations are direct offsets to wells […]
Probable reserves are those unproved reserves which analysis of geological and engineering data suggests are more likely than not to be recoverable. In this context, when probabilistic methods are used, there should be at least a 50% probability that the quantities actually recovered will equal or exceed the sum of estimated proved plus probable reserves.
