My knowledge on a Solar System back feeding the grid is very limited. From what I have read and heard people say it is a great deal more complicated that just installing a meter.

Here is one example I found.

How to connect a PV solar system to the utility grid

How to connect a PV solar system to the utility grid

sunwatts.com

I don't see what is so complicated about that. The "Line or Supply Side" model is used but there is a 2nd meter between the PV disconnect and the utility grid.

If I do not sell power to TVA then the disconnect is as shown in the picture. The meter is configured to only increment when power in incoming. Mechanical meters need a ratchet to keep the wheel from turning backwards if I am sourcing more than I draw. Many electronic meters default to counting power up no matter which way the power flows, meaning I would pay to put power in the grid.

We can only have one meter on our dwellings, work shop, business etc supplying electrical current.

That is what I describe. Only one meter supplying electrical power to me. Another meter supplying electrical power to the utility.

I gather from what you posted your electrical supplier advised you would have to get TVA to install a meter.

Suspect the utility would install it per TVA's instructions.

Sounds like a rather complicated system. The supplier is advising we will not pay you for electricity you will have to sell your surplus electricity to TVA. So that means TVA would have to install the necessary equipment to capture KWH‘s back feed into the suppliers system. They then would give you money which you could use to pay your supplier for electricity they provided which they had purchased from TVA to provide you.

Is just one more meter beside the first.

The local utility will read both meters and everything appears on one bill. Is just that I have to have contracts with both TVA and the local utility.

Before Smart Meters it was automatic...

Analog meters ran forward and backward.

Yes, but when PV systems appeared the utility learned to add a ratchet to the wheel preventing it from turning backwards.

Here they just replaced all to Smart…

What is the unit called and what is the cost of one and what
is the cost of hooking up to the grid?
Thanks for any info

Around here one must have the system "designed" by a holder of an NABCEP certificate to connect to the power grid. NABCEP is a solar industry lobbying group. The local NABCEP certificate holders have a monopoly and know it. And make the most of it.

Just across the state line I was told by a utility engineer doing a site survey of my future home that I could "do anything I want" on my side only they won't pay for my excess power. Also they will charge one-time $4000 to install a remote disconnect. To get TVA to pay for my excess power it has to be "designed" and approved by an NABCEP certificate holder.

It is roughly the same here. And for that reason I'll be using all that money I save vs going for a professional install and grid tie and buying batteries. 30kwh of lifepo4 is ~8k now and dropping, which would be more than sufficient get me through the night. I am looking into a hybrid system as well.

What is "Excess Power" ??????

Are you talking about installing a Solar Grid to generate power and then sell the excess generated during daylight hours to the local electrical provider?

Historically, power companies would give you a meter that goes in both ways, and you would receive net metering. The meter spins forward at night, and then starts to spin backwards during the day. But power companies decided that was a losing game, at least in areas I've researched. For example, you use 5kwh overnight, and 10kwh during the day. but then produced 15kw with your panels during the day(exporting the unused, causing your meter to spin backwards), your net would be zero, and your meter would read the same today as it did yesterday.

However, they have re-thought this process, and have decided to record forward movements and reverse movements differently. That way they can charge you 20c/kwh, but anything they receive from you, they can buy back at a reduced rate, say 10c/kwh. That way you produced 15kwh, you consumed 15kwh, but they could still charge you for 5kwh.

The Federal law governing grid-tie states the utility can charge a connect fee "to pay for the distribution network", and only has to pay the audited incremental cost of generation. For TVA that is $0.015/kWh plus fuel surcharge. A pittance.

For decades it was all about the high cost of generation… building a hydro project or losing nuclear plant and peaker plants.

It’s amazing how the tables turned and now it’s all about distribution as the cost to generate is only a fraction of the power bill.

If solar, wind and geo turned off PGE could not meet demand…

This is the exact reason I'm not interested in grid tie any more. Utilities are sticking it to people who are just trying to save money. And they're buying your energy at 1.5c/kwh, then what, reselling it to another customer at 15c/kwh? That number varies widely, we were 11c/kwh 3 months ago, now we're 17c/kwh, more than 50% increase out of the blue. I understand them not wanting to pay for transmission, only generation. However around here, generation is the bulk of energy cost, while transmission is considerably lower.

I heard that PGE is pushing a new thing where they can borrow your EV's power combined with a new regulation(not yet passed) that would require all EV's have 2 way plugs. That way during times of high demand they could sap your EV's power, then refuel it later. Of course the price they give you for your ev's power would be lower than the price they resell you the power to recharge your ev. Also it would put an additional cycles on your EV battery. The concept of my EV being a backup battery for my personal use, but not for the grid at large.
