Pasadena's Power Mix - Room for Improvement

Run on Sun is proud to call Pasadena home.  We absolutely love this place.  But it isn’t perfect, as evinced by the latest report on where Pasadena gets its power - that’s right, the 2016 Power Supply Content Label is now out, and it is a mixed bag to say the least!  Here’s our take…

Every year, California utilities are required to post a table that reflects the sources of the power that they provide, the “Power Supply Content Label."  We wrote about PWP’s energy mix when the previous label was published, and at the time we noted that coal constituted 34% of the energy supplied, with natural gas another 6% - a full 40% coming from fossil fuels.  Surely a year later the news would be better, right?

Not so much - here it is, read it and weep:

2016 Power Supply Content Label

ENERGY RESOURCES2016 PWP POWER MIX3 (Actual)2016 PWP GREEN POWER MIX4 (Actual)2016 CA POWER MIX2 (for comparison)
Eligible Renewable Total32%100%25%
- Biomass & Waste 16%   2%
- Geothermal 2%   4%
- Eligible Hydroelectric 1%   2%
- Solar 5% 100% 8%
- Wind 8%   9%
Coal 40% 0% 4%
Large Hydroelectric 4% 0% 10%
Natural Gas 12% 0% 37%
Nuclear 7% 0% 9%
Unspecified Sources of Power1 5% 0% 15%
TOTAL100%100%100%

Both coal and natural gas went up!  While the overall statewide mix is just 4% coal, PWP gets 10 times that much, a whopping 40%!  Combined with natural gas and 52% of our power comes from fossil fuels.  Moreover, half of the “renewables” comes from burning biomass and waste, thereby also contributing to greenhouse gas emissions!  (One bright spot - utility scale solar now accounts for 5% of all energy, up from zero the year before.)

Lest you think all of the small munis are as bad, not so.  Glendale Water and Power, in particular, is kicking PWP’s backside, with only 5% from coal, and just 29% from natural gas.  GWP also gets 26% of its power from wind!  (Here’s a link to their power label.)

PWP is making some strides, however.  Last year they replaced a 51-year-old steam plant with a combined cycle turbine unit that can produce power within minutes, compared to the 72-hour start time for the old system.  But at 52% fossil fuels, PWP still has a long way to go!

NEM 2.0 is Here - Now What?

Net Energy Metering 2.0, or NEM 2.0 for short, is now the law of the land, at least in SCE territory.  So what does that really mean for potential solar clients?  Here’s the scoop…

NEM 2.0 brings three changes to how new solar clients will be treated by SCE (customers of PWP, LADWP, or any other muni utility are unaffected).  Let’s take a quick run through each one:

  • A one-time application fee - new solar clients will be charged $75 as part of the interconnection application process.  (In the past there was no charge.)  Not a big deal, just another annoyance from SCE.
  • Switch to Time of Use rates - this is a much bigger deal.  Most residential customers are on a two-tiered rate structure with a “penalty” tier for users who exceed 4x baseline allocation.  Under that rate structure the maximum cost for energy is 31.224¢/kWh.
    Going forward, new solar customers will be charged based on when they use energy, not how much energy they use, with a Summer, on-peak energy cost of 44.665¢/kWh!  Ouch!  Peak hours are weekdays (holidays excepted) from 2-8 p.m.
  • Non-Bypassable Charges - Under the old rules, energy that was imported from the grid could be entirely offset by energy exported onto the grid.  Now, for every kilowatt hour imported, regardless of exports, the customer will pay a small (for now) non-bypassable charge of 2.25¢/kWh.  Again, the utilities were pressing for this to be a much higher number, but for now this is a relatively minor surcharge.

So what does this all mean?  The answer is, it varies.  For some clients, particularly those with west-facing roofs, they may actually do better under TOU rates than they would have staying on the old, tiered rate plan.  But to answer that question requires a proper analysis, and this is where potential solar clients need to do their homework and look closely at their solar bids.

Here’s what to look for.  Your potential installer should be requesting that you provide them with SCE’s “interval data” for your home.  This hour-by-hour data for the entire year allows for a proper analysis of your usage, and makes it possible to compare that historical usage with the modeled output of your proposed PV system.  If they aren’t asking for interval data, they are taking shortcuts with their savings analysis - likely in ways that inflate your potential savings on paper, only to result in disappointment down the road.

Run on Sun uses UtilityAPI to access SCE data securely, and we employ EnergyToolbase (pictured above) to do our analysis of your potential savings - two of the most highly respected and sophisticated tools in the solar industry.  We have the tools and the expertise to give you the most accurate projection of your future savings from solar - so let’s get started!

Solar Boom Devolves to Power "Glut"

The LA Times today is out with an article titled, “Energy goes to waste as state power glut grows“.  The article describes how as solar power has grown dramatically in the Golden State, it has lead to a problem that has caused the state to actually pay neighboring Arizona to take our surplus energy!  Meanwhile the IOUs are badgering the CPUC to allow them to spend billions on additional natural-gas-fired power plants!  This is crazy town, and points to the need to radically redesign the incentives provided to utilities in the state.  Here’s our take…

Utility-scale pv

According to the LA Times report, as recently as 2010, solar accounted for less than 1% of the electricity produced in California.  Fast-forward to last year and solar provided 13.8% of California’s electricity, with 9.6% from utility-scale projects like the one on the right, and an estimated 4.2% from residential and commercial installations.

Surely that is a good thing, as California continues on its path to getting 50% - and ultimately 100% - of its energy from renewables. But we aren’t going to get there paying our neighbors to take our surplus energy.  And it certainly makes no sense for utilities that are already overbuilt, to be spending ratepayer money on even more fossil-fueled generation capacity.

The perverse incentive here is that the IOUs - SCE, PG&E, and SDG&E - earn their money by building stuff, whether that stuff is used or not.  So it would seem that the trick here is to get them to build The Right Stuff, which certainly isn’t another natural gas peaker plant.  Instead, the clear winner here should be storage, particularly storage at utility scale. Bring enough intelligent storage into the mix and goodbye “Duck Curve” and hello a fossil-fuel-free future.

The CPUC should be providing the same rate-making incentive to build vast amounts of storage, even if at a premium price, rather than non-renewable generation capacity.  No renewable facility should ever have its output curtailed (as has happened 31% of the time in the first few months of this year), and no renewable energy should ever be exported to a neighboring state, except when such an export serves the economic interest of California ratepayers.

California is going to get to 100% renewables, we have to, as does the world.  We can and should show the way, but we will need to change the way utilities approach the problem if we are to get there anytime soon.

Run on Sun is Pasadena Solar!

Run on Sun has been doing Pasadena Solar for more than 10 years, but only now have we gotten around to dedicating a webpage just to Pasadena Solar! 

Pasadena City Hall - home to Run on Sun and Pasadena SolarWho loves Pasadena Solar?

I know, kinda silly (and foolish from an SEO perspective) but we figured we were fine as we were.  But then I looked at the search results on Google for “Pasadena Solar” and it was really depressing.  I mean seriously - read some of those reviews and you know that they are fake - but still their related websites were getting better rankings than ours!  Not acceptable!!!

So now, if you want to see a webpage that proudly proclaims its love for Pasadena Solar, we’ve got you covered - complete with this iconic image!

Oh, and because we do so much work in neighboring Altadena we are hoping to do a shout-out page for them too but we need an idea for the quintessential Altadena image - if you have ideas, please let us know!

NEM 2.0 is Coming - But Not Before July 1

As a solar installer working in SCE’s territory, we get messages from them on a regular basis, including those regarding the upcoming transition to NEM 2.0.  But the email we received today (actually two copies of it!) was a bit, how shall we say, high-strung?  Here’s our take.

NEM 2.0 will occur when the first of two events occurs: SCE interconnects enough residential and commercial solar projects to reach 5.0% of its total aggregate power demand, or July 1.  We have written before that SCE will never get to the 5% beforehand, so the deadline is 23:59:59 on June 30. 

So we were a tad perplexed to see this email today - here’s a sample:

417 MWs Remaining in NEM 1.0

As SCE gets closer to its Net Energy Metering (NEM) 1.0 Cap, we want to remind everyone of the importance of submitting complete and accurate interconnection request(s) (IRs). You should be receiving similar notifications within the online application system (i.e., PowerClerk).

Why is the 417 MWs remaining important?

For those applicants and customers with an existing IR moving through the interconnection process, we are sharing this information so that you may plan accordingly as SCE approaches its NEM 1.0 Cap. Once the cap is reached, the existing NEM tariff will close to new customers and the NEM 2.0 (NEM Successor) tariff will become available. With approximately 417 MWs remaining in the NEM 1.0 cap, this is a friendly reminder to please submit all documentation necessary for receiving service under NEM 1.0 and do so as soon as possible.

(Emphasis in the original.)

Wow - you would think that this might happen any day now, based on that language.  Except that it won’t - not even close.

Here are the underlying numbers:  SCE’s total cap is 2,240 MWs - a target it has been building toward since 2007!  As of today, in SCE’s territory, 1,823 MWs has been installed.  That means it has taken roughly  3,595 days to install that capacity, which works out to roughly half a Megawatt per day.  With 417 MWs left under the cap, and just under 58 days before July 1, we would have to be installing at the rate of 7.2 MWs/day!  Uh, no.  Just Not Going To Happen!

(If you would like to see exactly how much time we have before we hit the actual deadline, check out the Doomsday Clock on our Residential Solar page.)

However, the reality of that deadline does have consequences.  For potential commercial clients, sorry, but you are out of luck - there is just not enough time to get a new commercial project designed, permitted, constructed, and approved before July 1.

Potential residential clients are in a slightly better position, but only slightly as your window of opportunity is rapidly closing.  For example, we are already booked solid for the entire month of May with just SCE projects (we have pushed everyone else back to try and help as many as possible in SCE territory meet the deadline), and we can only guarantee an approved interconnection for NEM 1.0 by mid-June.  If you’ve been thinking about solar in SCE-land, please don’t wait, call or email us today!
