Caps certain public utility profit margins at four percent

S 5687 caps annual profit margins for public gas and electric corporations, as well as municipal utility companies, at 4% of their equity investment. The bill defines "profit margin" as the return on equity (calculated based on the commission-approved rate structure), directly limiting how much these utilities can earn from their operations. This policy change requires utilities to adjust their pricing or operations to stay within the 4% cap starting January 1st after the bill takes effect. The measure applies specifically to publicly regulated utilities, not private companies.
