I just switched from Geneco to Senoko after my contract with Genoco is up! Seems like the contract prices and promos are changing quite frequently, so post the good deals that u see at any one point in time here!

There's a current POSB rebate of $150 (till 31 Jul 2021)

Sidenote: I experimented with SP Wholesale for a few months too, but i only use around 200kwh per month, the savings from lower wholesale prices are lower than the signup bonuses from the different retailers, so i feel it's better to go with fixed price contracts from retailers plus the around $180 signup bonuses (for 2 year contract = around $7.50 additional discount per month)
