Maps, tools, and resources related to energy disruptions and infrastructure. A recent study of more than 50,000 adults with several common types of cancer found no increase for people living near high-voltage transmission lines. If properly configured, DC transmission could also help minimize operational issues such as under- or over-production of electricity or the need for increased ancillary services associated with renewable generation. You can find yourlocal distribution company by going to the Energy Networkswebsite. A new study commissioned by EIA examines the role of high-voltage direct current (HVDC) lines in integrating renewables resources into the electric grid. The project was undertaken as a close collaboration between General Electric of the US and ASEA of Sweden. JSTOR. . Non-dispatchable (or intermittent or variable) generation sources like solar and wind, however, depend on the resource availability, such as when the sun is shining or the wind is blowing. Data Source: Homeland Infrastructure Foundation-Level Data (HIFLD) and Energy Information Agency. Short, timely articles with graphics on energy, facts, issues, and trends. As a result, these technologies have limited capability to respond to generation dispatch signals. Radiation Control Programs There are two main issues that people sometimes associate with high-voltage lines; potential health risk from Electric and Magnetic Fields (EMF), and a negative impact on property values. Transmission Lines With the increase in exposure to all sources of EMFs, including cell phones, routers, computers and other household items, there may be a cumulative effect that we do not yet understand.

In any case, one must always be aware of the risk to any future sale of the property if there is a perception of a problem, whether fact-based or not. Because of this property, the exposure to an electromagnetic field you would receive from a power line decreases with distance. Each converter station housed six mercury arc valves groups, consisting each of seven valves, for a total of 42 valves in each converter. Power transmission lines facilitate the bulk transfer of electricity from a generating station to a local distribution network. Energy & Financial Markets: What Drives Crude Oil Prices? The increasing deployment and penetration of non-dispatchable renewable generation from resources like solar and wind can lead to electrical system operational issues, which include under- or over-generation during times of high or low electricity demand. The idea of sending hydroelectric power to Southern California had been proposed as early as the 1930s, but was opposed and scrapped. and is filed under Aging Infrastructure, Energy, National, Sustainability, The Infra Blog Contacts Contact : James Lindstrom Attached Files Click on title to download individual files attached to this item or download all files listed below as a compressed file.
