On technology transfer and utility-scale power storage

Vietnam's recent energy transition experience shows that grid congestion issues limit how fast a country can turn to solar PV and wind power. Utility-scale battery storage could alleviate problems by time-shifting the variable electricity production, deferring the urgency to upgrade the transmission network. However, the technology is hardly bankable now in low and middle-income countries. We propose that forming a collective of transmission network operators may accelerate access to this technology.
