Atlanta-based Southern Co. has agreed to expand its disclosures on risks from water shortages, in response to a shareholder resolution.

Investors in Southern, Virgina-based Dominion Power and PPL, based in Pennsylvania, asked the utilities several months ago to evaluate and disclose strategies for water risks, including low flows, thermal impacts, and emerging regulations.  The resolutions were withdrawn after the companies agreed.

Southern agreed to prepare a report on its water management philosophy, use, consumption and discharges, as well as any emerging risks. Southern is one of the nation's largest electric generators, with utilities operating in all three states involved in the region's water wars.

The Connecticut State Treasurer's office, the lead filer of the resolution, said Southern "has given shareholders the assurance that it will integrate these considerations into its long-term planning. "
