Shares of power producers climbed.

New York City's electric utility is preparing for new strains on the grid this summer as people who normally commute to work stay home as a result of the new coronavirus.

Consolidated Edison Inc. bought a dozen mobile generators and has made targeted upgrades in areas of Brooklyn where the power went out last summer, executives said at a recent hearing. Con Ed projects its peak demand this summer will be 10% lower than normal because businesses that typically use a large share of power - such as Broadway theaters, and many commercial office buildings - will either remain closed or lightly occupied.
