Did Avista Corp. buy or merge with Washington Water Power?
A. No. On January 1, 1999, Washington Water Power changed its name to Avista Corp., a change that created a cohesive identity for a company that had already become nationally known through several of its subsidiary companies. The name change was designed to position Avista and its subsidiaries under one common brand to provide flexibility beyond Washington Water Power’s utility identity and the limits of its geographic location.
