求一句话的英译汉

我们是第三世界阵营中的超级力量？ 【 在 yy19871118 (77粉丝团之66粉丝团之专业懒羊羊) 的大作中提到: 】 : We're a superpower with a third-world grid : Bill Richardson在文章中的一句话，不太明白什么意思，希望达人能帮忙意译一下

Here is the context: the Electric Power Research Institute, based in Palo Alto, California, estimates that demand for power in America has grown at twice the rate at which transmission capacity has increased in the past decade. The rapid growth of power-thirsty air conditioning systems has played a big part. “We’re a superpower with a third-world grid. We need a new grid,” Bill Richardson, the governor of New Mexico and a former federal energy secretary, told CNN. “The problem is that nobody is building enough transmission capacity.” 【 在 rayer1798 的大作中提到: 】 : 我们是第三世界阵营中的超级力量？

我们是一个只有发展中国家电网能力的超级大国 意思是他们电网能力满足不了国家的需要

我们是一个超级强国，但是我们的高压输电网能力与第三世界国家相同

美国的电网貌似都是在二战时期建造的，现在已经旧了。。。
