EPW might be worth considering. It sell electricity and has gas generation capacity. A DY of 8% has been rock solid over the past 3 years.

The real problem is that DUE was a gatekeeper; ie, it didn't depend on the vagaries of gas demand, that risk was held by the customers who paid DUE to transport the stuff. As, mostly, your factory/power station/gas stove is either running or its not, DUE was somewhat insulated from actual gas demand (but not entirely).

In many ways SYD is a gatekeeper also, but with higher risk, higher PE and lower DY.
