How should I complete the sentence?


I have the following sentence:

会社は（ ）ですか。...パワー電気です。

I guess you it should be translated as "What is this company? It's the Power
Company"?

A classmate suggested:

会社は **どこ** ですか。...パワー電気です

But then it would read "Where is the company? It's the Power Company", right?

How should I complete the sentence?
