After securing Sector Alpha, your next objective is to restore power to the Main Labs. Follow the newly updated objective marker on your mini-map. This will lead you through a series of ventilation shafts, requiring you to use your Morph Ball ability (R button). Once through the shafts, you'll emerge in a large power conduit chamber. The main power generator is offline. To reactivate it, you'll need to find three power cells scattered around the room. Use your Scan Visor to highlight their locations. Each power cell is guarded by a small group of Energy Leeches, which can drain your energy if they attach. Shoot them quickly to detach. Once all three power cells are inserted, interact with the central console to bring the Main Labs back online. This will also unlock new areas.
