PPL Rises 0.98% as Arizona Scraps REST Rules Traded 346th in 0.3 Billion Daily Volume

On August 20, 2025, PPL Corporation (PPL) saw a 0.98% rise in its stock price, with a trading volume of $0.30 billion, ranking 346th in daily trading activity. The movement reflects broader regulatory shifts in the energy sector impacting utility operations.

Arizona regulators initiated the repeal of the Renewable Energy Standard and Tariff (REST) rules, which mandated 15% renewable energy by 2025. The Arizona Corporation Commission cited rising costs and outdated targets, as major utilities like Arizona Public Service (APS) already exceeded the requirement. Pinnacle West, APS’s parent company, revised its carbon neutrality goals from “zero-carbon” to “carbon-neutral” by 2050, emphasizing cost-effective resource integration. The decision aligns with APS’s recent investments in solar, wind, and battery storage, aiming for 10.7 GW of clean energy capacity by 2028. Critics argue the repeal could deter renewable investments, but regulators stress flexibility in energy mix choices to meet Arizona’s growing demand.
