The utility billing system is preventing rate and program innovation

As the number of U.S. electricity rate tariffs has grown by roughly an order of magnitude in five years to over 50,000, traditional billing systems (CIS), due to outdated architecture and redundant logic, have become a key bottleneck for rate innovation and program implementation. GridX Chief Commercial Officer Scott Engstrom analyzes that rate implementation cycles take 18 to 36 months, far exceeding the 12-month requirement for pilot programs, and cause delays in projects such as virtual power plants and EV charging management. The article suggests decoupling rate calculation from core systems through solutions like modular billing engines, while also urging regulators to take action on approval, cost recovery, and performance metrics.

Starbucks Tests 24-Hour Replenishment Model to Eliminate Stockouts

Starbucks is testing a 24-hour operating model to enable same-day inventory replenishment and prevent stockouts, while also scaling daily delivery efforts.

Texas data center grid connection pause may affect 20% of projects under construction nationwide

BloombergNEF (BNEF) said in an analysis on Wednesday that Texas's suspension of data center grid connection reviews could put about 20% of data center projects nationwide at risk of delay. Governor Greg Abbott announced the suspension on Monday, affecting nearly 49.8 gigawatts of projects and triggering a comprehensive audit of the ERCOT interconnection queue. BNEF estimates that if 60% of the delayed capacity is AI-related, data center revenue losses could reach $8 billion by the first quarter of 2027.
