The Blues have also hired architecture firm Kohn Pedersen Fox to draw up plans for the construction of a 55,000-60,000-seater stadium.
A Chelsea spokesman said: “In the past, we’ve talked to various people with interests in Battersea Power Station, but we haven’t had any substantive discussions with anyone regarding that site for several months.
“However, in light of current developments, we now think it prudent to look again at the feasibility and potential for the BPS site to be developed for a football stadium.
“We have made no decision to leave Stamford Bridge, and we continue to discuss with the local council any economically viable options to expand the the Bridge, but we will continue to investigate various options close to Stamford Bridge.”
The Blues will still need to buy back the freehold of Stamford Bridge before they can leave the stadium.
