石油设备网讯 据路透社4月24日报道，挪威监管机构NVE周三表示，由于水力发电产量下降，高电价吸引了邻国的风电供应，挪威在2019年第一季度成为电力净进口国，扭转了过去5年净出口的趋势。
尽管拥有充足的水力发电，通常足以满足自身需求并推动出口，但挪威国内发电量在第二季度下降了近五分之一，至37.7太瓦时(TWh)，低于39.8太瓦时的需求。
挪威水资源和能源目录(NVE)的数据显示，挪威的电价在很大程度上取决于该国水电大坝的水位，2019年初，该国水电大坝的水位比正常水平低6.1%。
在截至3月底的三个月里，随着新风电场的加入，北欧地区的风力发电总量升至创纪录的13.8太瓦时。瑞典和丹麦产生11.0 太瓦时，挪威和芬兰产生其余的。
因此，瑞典的净电力出口为5.4太瓦时。NVE表示，在本季度的13周中，挪威有11周的电力进口超过了出口，净进口总额达到2.1太瓦时。
挪威大部分进口来自瑞典，其次是丹麦。德国也做出了贡献，因为该国的电力价格有时为负。当时，国内的风电瓶颈导致德国北部地区的风力发电经由丹麦输往挪威。
NVE表示，挪威的电价与2018年欧洲大陆电价以及碳、天然气和煤炭价格的上涨密切相关。
NVE一位发言人说，第一季度的电力进口是自2011年以来最高的，当时挪威在异常寒冷的冬季不得不进口6.4太瓦时。

Norway swings to importing power as domestic output falls short
Norway was a net importer of electricity in the first quarter of 2019, reversing a trend of net exports seen in the last five years, as hydropower output fell and high prices attracted wind power supplies from neighbours, regulator NVE said on Wednesday.
Despite having abundant hydropower, typically enough to power its own needs and drive exports, Norway saw its domestic production falling by nearly a fifth to 37.7 terawatt hours (TWh) in the quarter, short of its 39.8 TWh needs.
Power prices in Norway are largely dependent on the water levels of the country's hydropower dams, which were 6.1 percent lower than normal at the start of 2019, data from the Norwegian water resources and energy directory (NVE) showed.
Total wind power generation in the Nordic region rose to a record 13.8 TWh for the three months to the end of March as new wind farms were added to the system. Sweden and Denmark generated 11.0 TWh, with Norway and Finland generating the rest.
As a result, Sweden had net power exports of 5.4 TWh. Norway imported more power than it exported for 11 of the quarter's 13 weeks, NVE said, with its net imports totalling 2.1 TWh.
Most of Norway's imports came from Sweden, followed by Denmark. Germany also contributed as it saw negative power prices at times, when domestic bottlenecks sent wind power produced in northern parts of the country to Norway via Denmark.
Norway's electricity prices are also closely related to continental power prices which rose during 2018 along with the price of carbon, gas and coal, said NVE.
The first quarter's electricity imports were the highest since 2011, when Norway had to import 6.4 TWh during an unusually cold winter, an NVE spokesman said..
