World's Largest Green Energy Venture - Airvoice Group Project - India

10,000 Megawatt Solar and 3000 Megawatt Wind Energy Project

Airvoice Green Energy Pvt Ltd, New Delhi, India, announced the launch of an ambitious project in the renewable energy sector. It proposes to set up 10,000 MW of Solar Power and 3,000 MW of wind power in the state of Karnataka. 

The proposed solar power plant would be based on Photo Voltaic (PV) technology and will be implemented in . 12 high potential districts in the state of Karnataka.  This would be the largest solar power plant in the world till date. Currently the largest solar PV power plan in the world has a capacity of only 60MW based out of Spain. Sanjay Kapoor, the CMD of Airvoice Group, indicated in the press conference held at Villa Medici, The Taj Mahal Hotel in New Delhi, “this project alone would meet around half of the ambitious target of 20,000 MW as envisaged by the Jawaharlal National Solar Mission announced by the Honorable Prime Minister Sri Manmohan Singhji”. The Karnataka Renewable Energy Development Limited (KREDL), the nodal agency of renewable energy projects, has given in principle approval. The entire project would be done in 5 phases. Airvoice would be setting up a first phase pilot of 100MW capacity. The work has already started and it is expected that the detailed project report (DPR) would be submitted within the next 90 days.

Airvoice group has also identified 4 high potential districts where the wind farm would be set up. The first phase of the 3,000 MW wind farm project would be 200 MW and the work on the same has already started. It is expected that the DPR would be submitted in the next 4 months. 

Airvoice is entering into a JV partnership with Satluj Jal Vidyut Nigam Limited (SJVNL, Mini Navaratana) for the first phase of both the solar and wind power projects. S.P. Singh, GM of SJVNL, mentioned in the press conference that the board has in principle approved the partnership and the same would be submitted to the government.  SJVNL operates the largest hydro electric power plant in the country and now partnering with the largest renewable energy project in the world.

The problem is formulated into a pure integer programming model with the objective of minimizing the cycle time of the PCB
assembly line. Furthermore, the mathematical model is solved by the branch-and-bound
(B&B) algorithm in order to get the optimal solution. Finally, a numerical example is
presented to illustrate the mathematical model and the B&B algorithm.
