Explore Holland Energy Park’s Visitor Center at Open Hours during Tulip Time! The Visitor Center, called Energy Alley, consists of fantastic overlooks of our power plant floor and hands-on, interactive exhibits that are engaging for all ages. Visitors will experience the working power plant and learn more about electricity, energy efficiency, and Holland’s “electrifying” history! Activities will be available for kids including coloring and crafts. Guests are also encouraged to take advantage of our ¾ mile paved trail that highlights native gardens, prairie, and wetland habitats.
