The rate cuts in July and September are likely to have lowered utilities’ cost of capital, which, in turn might have impacted margins and the bottom line.Moreover, focus on environment-friendly generation, addition of energy storage projects, launch of technologies to maintain transmission and distribution lines as well as gradual introduction of smart meters have improved service quality and reliability. Customer growth and new rates in their service territories are likely to have made a positive impact on Utilities’ third-quarter earnings.Q3 PredictionsFor Utilities sector, Q3 earnings are expected to increase 4.7% year over year on 4.5% higher revenues.
