According to a parliamentary report, “the cost of developing such a supergrid could be very high...but it may bring a host of economic benefits – including tens of thousands of new jobs in the offshore renewable industry." A regional initiative would also allow Prime Minister David Cameron to accommodate opposition within his party to onshore renewable energy plants.
去年，英国在太阳能和风力发电站等洁净能源方面的投资达152亿美元，与德国相仿。但要达到其制定的气候目标的话英国还有很长的路要走。据一份议会报告指出，“建设这样一个超级电网的成本将极为高昂……但将带来大量经济利益——包括在离岸可再生能源行业的数万新工作职位。”一个区域性动议也将让首相戴维·卡梅伦得以安抚本党内那些反对建设内陆可再生能源发电站的声音。
