Supercharger Pricing in WA State

I'm curious about how SC pricing in WA state is determined and if fellow Tesla drivers even care. The data below was pulled from my car's SC map today.

Clearly, the metro Seattle area has the lowest pricing, with $.18/kwh except for 11 AM - 8 PM which is $.36/kwh.

The three most expensive in the state are Aberdeen and North Bend (both $.43/kwh) plus Burlington ($.40/kwh)

I have used the information to plan my trips as some of the neighboring pairs of SC have wide swings in pricing. For example, Centralia is $.38/kwh and Tumwater is $.37/kwh but Kelso is only $.26/kwh. Monroe is $.24/kwh on one side of Stevens Pass but Leavenworth is $.33/kwh on the other side.

For quick mental math, I just assume if you multiply the kwh price by 10 then you have the approx. gasoline-equivalent fuel cost. So paying $.25/kwh is like paying $2.50 for gas. I know that's not precise but it does allow for a quick mental comparison and maybe makes a more real cost per charge make sense.

Energy costs vary based on area and how power is generated. Land Lease rates and infrastructure costs all play into needing an ROI.
agree but I guess I'm wondering if people look at this and decide to skip an SC due to cost.

Driving from LA recently, I tried to minimize Cal SC due to their costs and stretching in Myrtle Creek, OR rather than the Medford area because my S could then reach Kelso skipping all other OR SC and also allowing me to skip the pricey Centralia SC

i thought Liberty Lake was the Spokane charger.
Liberty Lake was added as a part of the sales and service center that was built (and just opened) out there.

To make matters more confusing, the service center was originally in Spokane proper. The Spokane supercharger was then built (and is just outside of Spokane city limits). Then the sales department was added. Finally, the new sales and service center was built and opened.

I think you answered your own question.

Depends how much time I have... I'm in Seattle like every other week, so I'm well aware of the costs of the SC... When I have time, I'll stop by Northgate during the cheap hours... If I don't have time, I try to squeeze in Bellevue before 11am, even tho it's slower... But depending on how many clients I have to see and where, I won't be able to charge until I leave... Which may or may not be before 8pm. When everythign works out tho, I can definitely see the price difference... So a few weeks ago when I was driving up to Canada, I made sure to strategically stop to minimize costs, lol...

This is really an awareness thing. I haven’t seen any conversation about the SC costs which are pretty high compared to what residents pay to charge at home. I spend the winter in CA where “OFF PEAK” home rates are $.19 and peak is $.31. Home charging for me in Seattle is $.11 always and I’m producing a lot of free electricity with my solar panels.

I understand for some people the price doesn’t matter, convenience and getting on with the next thing is top of mind. I was definitely surprised when I realized how much the cost varies along I-5 and planned my SC visits accordingly. Also, with a new S I have a lot of range flexibility there’s might not have.
