Rseding is doing a lot of small optimisations for 0.15. The reason of the performance improvement is, that once decorative isn't regular entity, it doesn't need to be iterated over when doing area based entity search (typically for collision checks) and also the memory fragmentation is not that bad. Not only the save file has been reduced (46Mb to 25 Mb on my map), but the memory footprint and overall performance is better. The decoratives optimisations that were mentioned in the fff-157 are finished and working well. The plan is to have approximately 3 months to implement all the planned changes, so it could be expected around february 2017.
Conference registration is open through noon Eastern Time on June 22, 2017.There are many things we want to have finished for 0.15, so the estimate isn't precise. The 2017 EIA Energy Conference, held June 26 and 27 in Washington, DC, will examine current trends and key developments affecting energy at the state, national, and global level. Department of Energy’s Office of Nuclear Energy Bradley Williams, Senior Advisor for the U.S.Chris Mudrick, Senior VP for Northeast Operations, Exelon.Edward Kee, CEO of the Nuclear Economics Consulting Group.The panel will be moderated by Greg Adams, leader of EIA’s Coal and Uranium Analysis team. The 2017 EIA Energy Conference will include a session on the future of nuclear power, examining the competitive challenges facing the existing fleet and the options available to plant owners and regulators as they examine the role of nuclear energy in their generation portfolios. Those programs are currently subject to legal challenges that have yet to be adjudicated. New York and Illinois have already enacted programs to provide financial support to selected nuclear plants. In the announcement of its plan to retire Three Mile Island, Exelon noted that the plant had not been profitable for the past five years, and they sought subsidies from Pennsylvania to provide the financial support necessary to keep the plant open.
Pacific Gas & Electric, the owner of Diablo Canyon, chose not to seek a license extension, and the company now plans to retire the plant by the time its license expires.Įconomic factors have played a significant role in the decisions affecting the continued operation or retirement of nuclear power plants, as increased competition from natural gas and renewables has made it harder for nuclear generators to compete given slowing electricity demand growth. When the extension was challenged by the state of New York because of environmental and safety concerns, Entergy announced its decision to retire the plant. New nuclear plants are licensed to operate by the Nuclear Regulatory Commission for 40 years, but nearly 90% of currently operating nuclear power plants have applied for and received license extensions to operate for another 20 years.Įntergy, the owner of Indian Point, had initially applied for a license extension for the plant. Four of these-Palisades, Pilgrim, Oyster Creek, and Three Mile Island-have planned retirement dates more than a decade before their operating licenses expire. In addition to these recent retirements, six plants are scheduled to retire within the next nine years. In most of those cases, increased electricity generation from natural gas and coal made up for the reduced nuclear output in the months following nuclear plant shutdowns. In total, the five nuclear plants that retired in the past four years had a combined capacity of nearly 5,000 megawatts (MW). Since 2013, two more plants- Vermont Yankee in 2014 and Nebraska’s Fort Calhoun in 2016-have retired. Prior to the retirement of the Crystal River, Kewaunee, and San Onofre nuclear power plants in 2013, no nuclear reactor had been retired since 1998. Some of these retired plants were test projects or experimental designs, but most provided commercial power for some portion of their operational lives. nuclear reactor came online in 1957, more than 30 nuclear reactors have retired. Exelon’s announcement marks the sixth announced nuclear retirement in the past seven years.Ĭurrently, 99 nuclear reactors at 60 nuclear power plants operate in the United States. Energy Information Administration, Nuclear power plant data, Nuclear Regulatory Commission, and IAEA Power Reactor Information SystemĪt the end of May, Exelon, the owner of the Three Mile Island Nuclear Generating Station in southeastern Pennsylvania, announced its intention to retire the plant in 2019 unless the company is given assistance by the state to help keep the plant financially viable.
