P3 was the name of the successful nightclub in San Francisco started by Piper Halliwell and her sisters in 1999. The club was named after the Power of Three, in honor of Piper and her sisters. Piper sold the club sometime in 2008 in order to fulfill her dream of owning her own restaurant, Halliwell's.
Over the years the club was run by Piper, it went through several ups and downs, though it was generally a popular and successful nightclub and at times the only source of income for the sisters. Various magical and demonic events took place at P3 and it was a regular hangout for the sisters themselves as well.
The Industrial Zone
Before Piper bought the club in 1999, it was known as "The Industrial Zone". Prue said she used to go there often after work and that it was a great place. She noted that it would be a shame if Piper's loan didn't work out, as the place had a lot of potential.
The Beginning of P3
After Piper had quit her job at Quake, she started to make plans for her dream job. Although she couldn't open a restaurant, the closest she would get would be the owner of a nightclub. Piper was in the process of getting a business loan which would let her buy the building, but it collapsed when Jeremy Burns was resurrected by Abraxas and attacked there. Prue and Phoebe then got a second mortgage on the manor, which allowed Piper to buy the club. In return, they each got a minority stake and became silent partners.
The Big Break
P3 initially struggled to get a foothold. However, its big break came when the band Dishwalla performed there. Leo was responsible for this as he put the manager, Jeff Carlton, under a spell. Unbeknownst to Leo and the sisters, Carlton had made a pact with the demon Masselin, who offered to make him a successful manager if he would deliver him the souls of innocents. Carlton would trick fans into believing they would meet the band, only to end up devoured by Masselin. When Masselin devoured Jenny Gordon and several other women at P3, the sisters vanquished him. Due to Dishwalla's performance, P3 officially became success.
In Size Matters, P3 had a make-over and was totally changed, even the name changed into "The Spot". After Prue's death, the club was not doing so well and in an attempt to make it better, a manager was called in to change it. But at the end of the episode, Piper turned "The Spot" back into P3, after she finally fully accepted Paige, as well as the existence of the new Power of Three. Piper had mentioned that P3 stands for Prue, Piper and Phoebe to her new manager. Leo healed the P3 sign that was thrown out into the back.

In the alternate reality created by Cole Turner, Paige Matthews never reconstituted the Power of Three after the death of Prue, as she had also been killed by Shax. Consumed by bitterness and vengeance, Piper became a fierce demon hunter looking to vanquish Shax, while Phoebe became stuck in a loveless marriage to Cole. P3 was abandoned and fell into ruins.
- Piper Halliwell also temporarily used P3 to run a day care center. The club could also be rented for private parties and other events, such as baby showers, high school reunions and speed dating nights.
- Paige stated she started going to P3 about a year before Prue died. Paige went to the club because she felt a connection with the sisters, meaning she probably knew what they looked like. Therefore, it's possible that she and Prue have seen each other there without realizing they were related.
- One of the posters seen on the walls of P3 was of Chicago-Based Metal band Disturbed
