Is this all under one meter, or does she have multiple meters?

You need to figure out how much is usage based, and how much is fixed fees. If she has multiple meters and some of the fees are per meter, it may be worth considering rearranging so there's fewer meters, although that may not be the best for future use.

My house on 9 acres has 3 meters. One for the house, one for the well, and one for an outbuilding that was built before the house and used to be a woodshop. This arrangement would be handy if we subdivided and shared the well, or rented the shop to someone. Otoh, it's not very handy because the house is on a automatic generator and when utility power goes out, we have no water.

One meter. She has a barn with putside light on a seperate meter but those charges were seperated on the bill.

Her January bill listed 222.84 in generation services. 188.86 in fuel factor at 0.0413900 per kWh. 176.04 transmission services 101.02 distribution services

Some taxes etc and a final charge of 1359.78. I'm remembering now that they did overcharge her & we talked about that w the power company getting a credit for the next bill. My mistake on that. But for the last several months her bill has consistently been extremely high, 900 this past month, 1100 a prior month.

Her kWH usage is 4562 per month & I'm really not sure how she gets to that, she literally drives between 1 & 2 hours to work and back every day depending on location so she's only home in the evenings.

If my math is right, that's an average load of 6 kW. You should be able to track down big loads like that pretty quickly, I'd think.

Watch the meter, it's likely spinning quickly, turn off breakers and mark which ones have a big effect on the rate. Sometimes meters count too fast, but usually it's a couple % and more often is in the other direction especially with mechanical meters.

Which state is she in, and who's her electricity provider? If she used 4562 kWh this month and her bill was between $900 - $1360, that means she's paying 19¢-29¢/kWh, which is quite high (but not impossibly so, especially in California or Hawaii): https://www.electricchoice.com/electricity-prices-by-state/

I'd first still do what everyone is suggesting (identifying the actual loads that are using so much power), but on top of that, it might be worth looking at the details of your utility's rate plan and comparing different ones (if they have them), or maybe even a different electricity provider if your state and jurisdiction allow those. (It's usually a case where you end up paying the electric utility for transmission, but someone else for generation... there are a lot of third parties that build out big solar/wind farms and then contract with the utility. But be careful and do your research carefully if you choose to go that route, since many of them are nearly scams that lure you in with an cheap upfront cost and then drastically raise your rate later. But then again, the utility itself can do that too, depending on state laws...)

At the end of the day, once you identify the loads, you can better assess what combination of 1) conservation 2) time-of-use shifting or possible rate plan changes 3) insulation & lighting improvements 4) home solar/hydro 5) equipment upgrades to do (in order of least to most out-of-pocket costs).

You're using enough power (as in abnormally so, unless you have some commercial/industrial loads on that land, like for ranching/processing/growing operations?) that you shouldn't just blindly throw solar at it without understanding what's using that much power to begin with. The solar should pay itself back regardless, but if you can lower the power draws to begin with and size your array accordingly, you don't have to get as big an array. Oversizing a solar array not only costs more upfront, but may have very limited returns because many jurisdictions cap what the utility pays you for home solar. If it's much greater than your actual usage, basically you just end up providing free (or nearly free) electricity for the grid.

If she's usually away from home and there's no unusual loads going on, the house really shouldn't use that much power just idling. Check the circuits, major appliances (heating/cooling/refrigeration/space heating), lights (any old incandescents lying around, especially porch lights etc. that might be left on 24/7? grow lights for weed or other crops?). Hot tub? Heated driveway? Anything having to do with heating/cooling? For any plug-in appliances, you can also get a plug-in power meter (like a "Kill-a-Watt" or similar) to see exactly how much energy they're using over a day.
