Green enclosures w/ natgas near utility poles?

[LightningCrash]

I've noticed green steel enclosures near utility poles, maybe 4Wx6Dx4H, with a natgas feed. There is no discernible exhaust pipe and no meter on the natgas.
They appear to be fed electric from the utility pole they're near.

I've only noticed them near neighborhoods and light commercial space.

Any idea what they are?

My current theory is that they somehow cut electricity to a neighborhood in the event of a gas pressure drop.

Its all part of the plan.

Reddog told me they were NWO robotic land drones. When the time comes they will rise up like Transformers and attack.

Those are the nodes for Cox or ATT, in the event of a power loss from the utility company they are NG feed with a GENSET inside of them and can continue to run. Sometimes an electric outage is not very widespread, but if that node goes offline it may knock out cable/internet to a large area, this way they can still provide service to people who still have power.

ATT would make sense, hooking into direct bury. I didn't see any cable lines coming to it.

It did look a bit like the thing in the pdf

This is exactly what they are. They are Cox power supplies. They run off of electric under normal operating conditions but when power is lost they switch over to battery while the natural gas generator starts up and kicks on. They then switch over to the natural gas generator. I can tell you as a former Cox employee that had a cubicle near the employees that monitored these that I would hear the alarms go off when various parts of town would experience an electric outage.
