eVgo Charging Stations ... a pricing strategy gone wrong

Tue Nov 23, 2010 4:12 pm

Lots of news on NRG/Reliant placing 150 the eVgo charging stations here in Houston including 50 fast-charge DC stations. Great news... but a WACKY pricing model! (https://www.evgonetwork.com/) They want to charge $89/month for unlimited use of the home charging stations and the mobile charging stations with a minimum 3 year contract (which includes "free" installation of the home charger). I cannot for the life of me figure out how the math makes sense to anyone on this:

Let's assume the charger costs $2,000 (half of which is covered by a tax credit). Over 36 months the charger installation is worth around $30/month. So for $59/month you get free electricity and access to the eVgo charging stations.

A full charge (from zero) is 24 kwh. Houston power prices (fixed for 24 months) run 9.8 cents kwh from Reliant (expensive option). So let's call that $2.35 per full charge and let's assume you get 80 miles per charge...

If you drive 12,000 per year you use $30/month in electricity. So you are paying an additional $1,100 for access to the charging stations for 3 years. That is a lot of $$$ up front just to get the occasional public recharge!

I sure hope they end up doing a pay-as-you-go option on the charging stations rather than this wacky subscription service!

I'm sure there will be plenty of models like this. I think it's crazy to pay $2200 for a $150 box installed on the wall. Paying per month makes little sense.

Unlimited electricity for $89/mo? Even with a wacky J1772 connector, there are people who will figure out how to run grow lights off this. :)

They install their EVSE at your home (in your garage, for example) AND install a new service feed, meter, panel, breaker, and wiring, AND then THEY pay for the electricity you use through their EVSE?

If your garage is attached, I can't see how they'd have separate metering. Per the NEC buildings can only have 1 meter. Texas may allow separately billed submeters, though, which I suppose could billed separately, but if its at the Residential rate + monthly fees, the cost of electricity to your home for them would be more than probably just running a line off your panel.

Or, to get around NEC, they might just mount a pedestal in your driveway since that would be a separate structure and could have its own meter; but then you'd have to always park outside. :roll:

Heck, you could subcontract to the entire neighborhood!

There's got to be more to it than "buildings can only have 1 meter"; I see buildings from multi-family residential (duplexs on up) to commercial with multiple meters which are not submeters. OTOH, most electrical codes are picky about building disconnects, using language such as "no more than 3 motions of the hand" to disconnect an entire building.

I would guess for those multi-family residentials the main meter is somewhere else, maybe even on a stalk somewhere. The point of the single meter is simply the single shut-off for the Fire Marshal. NEC 2005 (which we use in the Commonwealth of Virginia) strictly prohibits multiple meters per structure. Later NECs (2008 or 2011) may add provisions for firewall separation as long as the electrical circuits are isolated and a special plaque next to one primary meter indicating where the alternate meters are located.

When I post the TOU FAQ to my blog, I'll spell all this out.

Perhaps Virginia has amended the NEC in this regard, because the NEC itself definitely alows multiple shut-offs on a building.

The basic rule is in 230.71 which says that a set of service entrance conductors shall feed at most six disconnects, which must be physically grouped together. Typically a building is limited to one set of service entrance conductors, but there are exceptions given in 230.2 and 230.40. So for a multifamily dwelling with a single service, you can have up to 5 units without a main disconnect, just the six individual disconnects for the 5 units and the house panel. Above 5 units you would need to use a different arrangement, such as a main disconnect.

As to the meters themselves, the NEC doesn't really care, it just cares about the disconnects. The meters can be wherever they are needed.
