In SC4 the "Up26x8_WindPower_1F45" power station that uses the "BatesMotel" building on a concrete pad can produce a nice explosion. I had 3 of them blow up at the same time. They're labeled "Cheap to build and squeaky clean", $50 . The plant condition was 100% before the event. The sky turned orange then BOOM, 3 craters and a large very large tile was covered in radiation. I had just openned up the city and a few minutes later, abandoned. Lucky I had made a backup the night before.
