Vietnam's state power utility EVN has restructured its electricity pricing model by eliminating morning peak rates and consolidating all surge pricing to the evening period, with the evening peak pricing window extended by two hours [1]. This significant policy shift reflects Vietnam's successful expansion of solar generation capacity, which has alleviated daytime power supply constraints that previously justified morning peak pricing [1]. The pricing restructuring directly addresses the fundamental mismatch between solar generation patterns—which peak during daylight hours—and the utility's need to manage grid strain during periods of highest demand [1].
The elimination of morning peak rates signals confidence in Vietnam's growing solar infrastructure to meet daytime electricity demand without requiring price incentives to reduce consumption [1]. Conversely, the extension and consolidation of peak pricing to evening hours underscores the persistent challenge of managing electricity demand when solar generation falls away, making evening the new critical period for grid management [1]. These changes represent a strategic recalibration of Vietnam's power pricing framework to align with the country's renewable energy transition and the operational realities of a grid increasingly dependent on solar generation [1].
CONCLUSION
Vietnam's restructuring of peak power pricing demonstrates how rapid solar capacity growth is fundamentally reshaping electricity market dynamics and utility operations. The shift from morning to evening peak pricing reflects both the success of renewable energy deployment and the emerging challenge of managing evening demand when solar generation is unavailable, signaling a maturing renewable energy market requiring adaptive grid management strategies.
