Residential Solar Savings

Does the hour matter on Residential Solar Savings? No — one rate, every hour of the year.

  • off-peak12.09¢

There is no peak and no off-peak here: 12.09¢ per kilowatt-hour at 3am is the same as at 6pm, on a Sunday as on a Tuesday, in July as in January. Moving laundry or car charging to another time of day will not change this bill by a cent. What does change it is how much you use, and the fixed charge below, which you pay whether you use anything or not.

What does Residential Solar Savings cost a year?

This plan is for homes that generate their own power — the tariff is named “Solar”. It is a real, currently open tariff, but the figures below are wrong for it: our three modelled households have no panels, so they earn none of the export credits that make this rate worth choosing and pay full price for every kilowatt-hour instead. Read the numbers as an upper bound, not an estimate, and see the tariff document for the export terms. We leave it out of the plan-to-plan comparisons.

Estimates, not quotes. We run three made-up but realistic households through this tariff hour by hour for a full year — including the way air conditioning loads the afternoon and an EV loads the small hours. Your own bill depends on when you actually use electricity, which is exactly the thing a per-kWh number hides.

Should you be on Residential Solar Savings?

One rate, every hour of the year. That makes this plan predictable and nothing else: there is no cheap window to move laundry or car charging into, and no penalty for running the oven at six in the evening. Predictability is worth something if your schedule is not yours to control — but if it is, a flat rate is the one structure that guarantees you cannot benefit from it.

Before a single kilowatt-hour moves, this plan charges $180 a year in fixed fees. On the apartment above that is 23% of the whole bill; on the house with a car charging in it, 10%. Fixed charges are invisible in a cents-per-kWh comparison and they punish small users hardest — if you use very little electricity, the headline rate is the least important number on this page.

Expect the bill to move with the calendar. The same family home costs about $148 in July and $87 in February — a $61 spread driven by heating and cooling far more than by anything you chose. Budget against the July figure, not the average, and a summer bill stops being a surprise.

Other Denton County Elec Coop plans

Who can be on Denton County Elec Coop’s Residential Solar Savings?

Eligibility is not our judgement — it is written into the tariff Denton County Elec Coop filed. This is what that document says:

Applicable to all residential Customers taking the type of service described in this rate schedule upon request by the Customer for all of the Electric Service supplied at one Point of Delivery and measured through one Meter used for domestic uses associated with the operation of a single-family or multi-family residential installation. Not applicable to temporary or shared service.

Shortened — the clause runs longer in the filing. Quoted from the filed tariff. Your utility decides eligibility, not us; check with them before you switch.
