Clean Power 2012 SEPA Utility Solar Rankings

Top 10 Solar Utilities (x 2)

Utilities + solar — it’s a hot topic. And it’s not always a peaceful topic. Today, we’ll lighten things up a bit with a couple of positive utilities + solar lists in this Solar Love repost.

The Solar Electric Power Association (SEPA) recently released its latest SEPA Utility Solar Rankings. Of course, there are different ways to rank a utility on its solar merits, so we’re including SEPA’s main two lists/rankings below. First, however, a note from our sponsors….

2012 SEPA Utility Solar Rankings

Our sponsors, in all honesty, are you, common citizens and clean energy advocates. Our focus is on bringing more cleantech to the world so that we can combat global warming and avoid its worst effects… as well as other types of societal harm from dirty tech.

The note I wanted to make is that, yes, some utilities are doing more to be good “citizens” and reduce their carbon dioxide contribution. However, for the most part, the utility network and engrained utility models are having a hard time coming to grips with the fact that the grid is changing and distributed renewable energy is the future… and the future is now. We’ve got a plethora of articles all about these matters, some of which are quite demonizing. And the demonization is quite warranted in many cases. However, it is also worth noting that some utilities are making notable strides forward (either against their will or voluntarily). So, with my brief contextual note out of the way, let’s go ahead and drool over not one but two Top 10 lists.

Top 10 Utilities For Solar (Per Customer)

I am a fan of relative rankings — this is what shows one’s true colors. So, I’ll start with SEPA’s rankings for the top 10 utilities for solar power watts per customer. Here’s is the list:

Following the rank and utility names, the categories are for watts/customer, state, region, and type of utility.

Top 10 Utilities For Solar (Total Installation Capacity)

And here’s the list for top 10 utilities based on total solar power installation capacity:

Not a lot of overlap there, eh?

    Per person always shows interesting stuff. Yes it looks like most are it location with small person counts but still.
    That fact the (2,4,6) are in sunny HI (where there are FITs) is easy to understand. Then I see (1, 3, 9) all in northwest Ohio, what!. Ohio has not exactly been totally welcoming to PV and wind. But those are three city owned power systems, so looks like the local people decide it saved them money to go green.

      Yeah, that Ohio showing is shocking. Shows that local initiatives are possible almost anywhere.
