When asked, a BSES spokesperson said that at present, around 28% of long-term arrangements of the BSES (BRPL and BYPL combined) comprise green power, which includes pure-play renewable power of over 15% and about 13% of hydropower. "The share of green energy in Reliance Infrastructure led BSES's power portfolio has been progressively increasing over time. BSES is replacing costly power from old thermal plants, whose PPAs have expired, with renewables now," said the spokesperson. Tata Power Delhi Distribution Limited (TPDDL), which supplies power to north and northwest Delhi, is the only discom in the city that has managed to meet 100% of the RPO targets every year since 2016. The problem of missing RPO targets is not just in Delhi. A Niti Aayog report, Turning around the power distribution sector, published last month stated: "In 2019–20, only four states—already rich in RE generation—achieved or exceeded their RPO target: Karnataka, Andhra Pradesh, Rajasthan and Tamil Nadu.
