I'd feel way more comfortable with DEL going into a finance agreement with BKW over Palisade (If it was an option). Obviously they'd both benefit from such a deal as BKW need that Green gas solution for all their plants across Australia. The Palisade deal was rough, it didn't really benefit DEL other than the asset value of the projects.
Palisade would only care about the return whereas BKW would be more passionate about the Green gas production, growth potentials and collaboration with DEL. Biomethane into the grid is just one aspect of the market, another would be rLPG's (A greener solution of LPG's for both businesses and customers). I did some research and rLPG's market is growing at 18.5% pa expecting to be worth $7.5b USD by 2030. Obviously BKW would benefit from this market too.
