Adding DPF to 350KW Generac

A natural gas conversion would be less costly and very clean and efficient.

Diesel can be trucked in after an earthquake. Kind of hard to do that with natural gas.

True, but not many earthquakes in MA.

True, I was referring more to Ultrarunner's hospital genset in CA where they are fairly earthquake prone.

25 years ago we had natural gas generator but when code changes after Loma Preita onsite fuel storage mandated... either propane or diesel meets code.

I'm looking at retirement of the Hospital Onan Cummins generatir that has 660 hours and performs flawlessly since 1995 and that's the problem... 1995 emission controls.

Why do they think that emission controls will make any difference to the world when one engine is operated
a few hours a month .
Some standby applications only have to meet Tier II or Tier III rage and not Tier IV .
Sounds like some righteous @$$hole has found a 田ause and it running around proudly thumping their chest .

Any electrician could move that system for a few grand worth of wire, some trench time and moving the unit. Talk about over inflated government bids. Just adding dpf wont do a thing.

I install high voltage systems all the time before retiring. This probably involves either 2 or 3 parallel runs of wire and some control wire. Not sure if asphalt drive is involved or not....that could definitely increase costs.

Yep... doesn't make a lot of sense.... 26.2 hours per year total over 25 years and a big chunk of that time is when the utility shuts down the grid for days at a time... tissue bank, cryo-freezer, etc need to be powered around the clock.

When the local grocery has seafood sales the refrigerated trucks run all weekend...

But it's not just generators... it's wood chippers, ag pumps, etc...

For sure. Town's "responsible official" and an outside "expert" said $100,000. I say 10 grand and someone would be making a lot of money at that figure.

The problem could be CARB. At the school district where I was a Facilities Manager our district office was on 26 acres. When I built it in 1995 we installed two 750 kva generators for back up power. Years later I built an Emergency Command Center building which had its own generator. A few more years later we wanted to upgrade our Main server room with its own backup generator as it was previously run off of one of the 750s, we were not allowed as CARB limited the site to 3 generators unless they were a certain distance apart. I forget the exact distance but it was in the 300 foot + range. Site was not big enough to accommodate. Made no sense but that was the regulation.
