limits.

Any municipality owning or operating its own system of

generating or distributing energy or utilities, and any municipality

engaged in the distribution of energy or utilities, may extend its

lines, mains, and channels together with necessary appurtenances

beyond the corporate limits of the municipality. Such municipality

may acquire, erect, construct and own all necessary poles, wire,

lines, pipelines, mains, channels together with necessary

appurtenances, apparatus and substations, and acquire rights-of-way,

and do all other things necessary and proper in carrying on the

business outside of the corporate limits of the municipality to the

same effect as it may now do within the corporate limits of the

municipality. Such municipality may construct or acquire lines,

pipelines, mains or channels together with necessary appurtenances

by purchase or otherwise and may sell such service to any person,

firm or corporation outside of the limits of the municipality.
