Hii..

You have perform quite well in Wbjee exams and I think you can get a seat both in ECE at Kalyani Government Engineering College and power Engineering at Jadavpur University.

Other than this you can try for some other departments at Jadavpur University also. There are other Government Engineering Colleges as well through wbjee exams like Jalpaiguri Government Engineering College and Maulana Abdul Kalam Azad University of Technology. You can also get your desired branch at  these colleges.

Hope it helps. 

Best of luck for your future.
