After the successful completion of the 4th extension of Tarbela project, World Bank (WB) is pushing ahead with plans for starting the next phase of its renewable energy plans for Pakistan, namely Tarbela 5th extension. By using Tarbela 4th as a benchmark, World Bank is confident Tarbela 5 can also be “put into operation in 4 years”, generating $200m worth of additional revenue for WAPDA per annum. The unexpected timely completion of Tarbela 4th extension has increased the confidence of WB as well as the investors including Asia Infrastructure Investment Bank (AIIB).
WB appreciated the timely completion of 4th extension project stating that global statistics for hydropower average around 90% cost overrun and 70% project duration delay. But this project was not only completed on time it was also completed below the expected cost.
The successful completion of Tarbela 5 would increase the capacity of Tarbela from 4888 MW to 6298 MW, making it amongst the top 10 hydropower stations of the world. It would also significantly enhance WAPDA’s financial capability, allowing it to invest the significant proceeds from Tarbela 4 and 5 towards the expansion of the Indus cascade
