A major milestone in power sector to interconnect Rayalaseema and Coastal Andhra

 A major milestone in power sector to interconnect  Rayalaseema and Coastal Andhra

As part of this, the Transco is working on interconnection of electric power networks to supply power and power services of high quality with high reliability to consumers on the whole regions of interconnection. The Transco has proposed a 400 KV line from 400 KV Talaricheruvu substation to 400 KV Podili sub-stations which interconnects the Rayalaseema and Coastal regions.   

The State government has proposed addition of solar power in Rayalaseema region by APGECL, where the demand for power is less than the generation, due to which more power has to be exported to Power Grid Corporation of India Ltd (PGCIL) network. To avoid this, the Transco proposed to interconnect Rayalaseema and Coastal regions to transmit excess solar power, generated by APGECLsolarparks, between the two regions. This will help to utilize the excess power to meet local requirements in various sectors, including industries, agriculture, domestic and commercial which will provide economic benefits to the State”.

Further, bus reactors were commissioned at 400 kv substations at Hindupur of Anantapuram district, Podili of Prakasam district and Rachagunneri of Chittoor district to address the over voltage problems of the 400 kv lines. This in turn helps in reducing the inter-state reactive power drawls and will avoid the penalties on that account.

For evacuation of power from the 10000 MW solar power plants, which were planned for supply of day time 9 hours free power to the agriculture services, the APTRANSCO hasprepared the transmission evacuation scheme with optimum budget dulyutilizing the available resources.

The evacuation facilities are being taken up with an estimated cost of Rs. 1349 crore for evacuation of power from 6100 MW solar power plants in phase-1. As part of the evacuation scheme, new power transformers are going to be commissioned in 400 kv Talaricheruvu, Jammalamadugu and Uravakonda substations and construction of new 220 kv switching stations are proposed at Mudigubba and Pendlimarri.

Further, a 132 kv Pamuru Sub Station is being upgraded to 220 kv level and new 220 kv transmission lines are going to be established for evacuation of power from CS Puram and Rudrasamudram Solar parks in Prakasam district.

The ultimate objective of Govt. is to provide cost effective and reliable power (24×7) with high quality to consumers and strengthen power utilities in the public sector to benefit people of the State in future as well.
