The next in-game event for Pokemon Go will be a shocking one, as the Electric-type themed Power Plant event comes to the game this week.

Power Plant begins on January 19 at 10 AM local time, running until February 1 at 10 AM local time. The event will focus on Electric-type Pokemon, with a focus on those from the Kanto and Kalos regions. The Kalos-born Helioptile will make its debut in Pokemon Go during the event, as will its evolved form Heliolisk--obtained by using 50 Helioptile Candy and a Sun Stone on a captured Helioptile.

The Power Plant event will also include a side event focused around Team Rocket Go. This side task--called "A Bad Feeling…" in the official blog post--will see more frequent appearances by Team Rocket Go both in balloons on-screen and at PokeStops. "A Bad Feeling…" begins January 24 at midnight local time.
