20,000 Tidalwatts

A visit to North America’s only tidal electric generating plant - Wednesday, October 1

By morning the WiFi still wasn’t working so we disconnected and headed back down the road to the tidal generating plant. We’d passed it last night and it was just around a bend in the road. In fact it was visible from our campground. A sign at the entrance to the parking lot said “Annapolis Tidal Generating Station - North America’s Only Tidal Power Plant - 20,000 kw - Visitors Welcome”. Another sign said, “Closed for the Season”. But the parking lot was open and we got out to take pictures.

The generating plant sits on a causeway, which is a manmade barrier across a body of water, in this case a tidal branch off the Bay of Fundy. The causeway is built to support a road, and there is always a break in it where the water can flow back and forth. The break is bridged, usually with a drawbridge if the waterway is navigable, which in this case it is. The tide was coming in and there was a strong flow evident but it was going through a bypass and not through the generator’s turbine.

We wandered around taking pictures, and at one point I strayed into an area where the public is not supposed to go. There were no signs and no fence, so I didn’t do it deliberately, but soon I saw a man walking briskly and heading straight for me. He told me very politely that the area is not open to the public and I apologized for the intrusion. As we walked back to the road I asked him some questions about the plant, and by the time we got to the road and met Madolyn he stopped and spent a good half hour talking to us and explaining the history and operation of the plant.

They usually do tours for visitors and take you underground to see the turbine, but the turbine has a bad blade and it is being repaired, so the plant is shut down and not open at this time. Our friend is a station engineer and has done some of the guided tours in the past. He loves his work and we were very lucky to have such a knowledgeable person take the time to talk to us.

Engineers have discussed the possibility of using tidal power to generate electricity for years, but there are several problems that have to be solved to do so. Most sites that have high enough tides (you need about 10 feet of tidal head) have tides that fluctuate a lot more than that, and there are also the problems of what to do about the silt that comes in twice each day with every tide, and about the corrosive actio
