I am providing you with experience and alternatives that I am personally aware of as an engineer in this business. My comments do not necessarily apply to a single LLEG project.
70MW may be divided into many forms of combined heat and power (CHP). I.e: hot water, steam, Biogas, Synfuel, electricity, chilled water, ice making, or pumping energy. In Colorado for example, there is a major stored water facility in the mountains above Boulder. Water is pumped up at night at low $/kWH, and flows down during the day to generate power; an alternative energy assist there would soak up a lot of MWs.
If LLEG ran into a snag with the PUC approval you are addressing, they have alternative opportunities that they could promptly consider. Just because they haven't published that doesn't mean it isn't readily doable or a part of Plan B, Plan C, or future expansions.
Note: A moderate sized brick plant that sits on about 15 acres uses 300MM BTUs of fuel gas energy per day. If there are 20+ acres to spare at the LLEG plant site, inviting a brick plant (..or foundry..) to move in (..or building one..) would be a very wise move. When construction is not in the total doldrums a brick plant is a very dependable base load.
