Memphis Light, Gas and Water (MLGW) GSA Part 3 — EV fast-charging electricity cost

MLGW GSA Part 3 is the filed rate schedule ForgeAsset models for DC fast-charging sites in Memphis Light, Gas and Water territory in Tennessee. Energy prices at 9.7¢/kWh flat; the demand side bills $18.47/kW of monthly peak. For one reference Supercharger site held constant across the whole library, that works out to 49.6¢/kWh per dispensed kWh — rank 65 of 86 filed tariffs (1 = least expensive).

Modeled rates

Non-time-differentiated schedule — the three TOU rates carry the same bundled value, month-weighted across MLGW's three seasons. Demand is billed per kW of the site's monthly peak; the first-block rate is folded across the full peak, which slightly overstates cost above 1,000 kW. Rates fold the trailing-twelve-month fuel cost adjustment and Tennessee's 7% sales tax, which applies to demand charges as well. The schedule's 30% ratchet resolves to the current-month peak under the model's standing billed-peak assumption.

The filed rate book for this territory records no EV-specific commercial rate, so the modeled cost is the standard schedule. Demand follows the model's conservative convention — 150 kW per stall billed every month, the worst-case coincident peak — so a site whose metered peak runs below that would see a lower demand line. Memphis Light, Gas and Water has not adopted TVA's EV charging rate.

What the reference site pays here

Reference site: 8 Tesla V4 stalls at 235 kWh/stall/day (57,183 kWh dispensed per month), a 150kW per-stall demand assumption, the model's default time-of-use mix, and a 12% loss gross-up — identical to the full utility ranking, where this tariff sits at position 65 of 86.

The rest of the Tennessee picture

The tariff is one layer. State taxes, incentives, clean-fuels programs, and the charging market shape the remainder — Tesla Supercharger ROI in Tennessee covers them, and the US Supercharger Economics Map shows every US Supercharger over utility territories colored by this same effective-cost derivation.

Memphis Light, Gas and Water (MLGW) GSA Part 3 — questions

What does Memphis Light, Gas and Water (MLGW) charge for energy on GSA Part 3?

Does GSA Part 3 carry a demand charge?

Yes: $18.47/kW of monthly peak. For a reference 8-stall site at 150 kW per stall that comes to about $22,166 per month.

What does electricity cost per kWh dispensed on this tariff?

For the reference site — 8 Tesla V4 stalls dispensing 235 kWh per stall per day, with a 12% loss gross-up — the all-in utility cost works out to 49.6¢/kWh per dispensed kWh, rank 65 of 86 tariffs in the library (1 = least expensive).
