With Response Times Increasing, SCE Unilaterally Doubles Processing Times - Where's the CPUC???

Some people are simply shameless, and it appears that the powers-that-be at SCE are among them. We just got this charming missive from the division at SCE that is responsible for processing Interconnection Applications:

Subject: Extended NEM Application Processing Timelines

Hello Contractors and Installers,

We are currently experiencing a high volume of new NEM applications. As a result, processing timelines are taking longer than expected. Please note, Interconnection Requests (IRs) may exceed our average processing timelines. Although most applications will be reviewed within 10 business days, some may take up to 20 business days to review.

To help mitigate this volume, we strongly recommend that you submit your application and the required documents in complete form, including all signatures and attachments. Ensuring that your applications are submitted in complete form helps us to minimize the number of touchpoints and reduce the application queue.

We request your cooperation and understanding as we work diligently in decreasing the application volume. Please refer to PowerClerk for the latest status of your application. If you have any additional questions, please send an email to Customer.Generation@sce.com.

Sincerely,

Eduyng Castano
Senior Manager of Customer Generation Programs
Southern California Edison

To deem this outrageous is to be way too kind. Gee, I wonder why there is a high volume of applications? Could it be because the bottom is dropping out of solar economics in SCE territory after the April 14th deadline? Who could have predicted that - apart from pretty much everyone who is paying attention. And how is it that SCE can unilaterally change the requirement for them to process applications? Doesn’t the CPUC have something to say about this?

The existing standard of 10 business days - two weeks on the calendar - was already a joke, but now they are saying that “some” applications could take 20 business days - nearly a month! Oh and to add insult to injury, they also raised the application fee - you know, the money that is supposed to cover application processing - by 25%! Must be nice to be able to jack the price that you are charging, while simultaneously reducing the service provided. Aren’t monopolies swell?

This is getting real folks. In an earlier post - find it here - we stated that we couldn’t guarantee NEM 2.0 for applications submitted after March 31st. But given this revision - and zero clarity on which applications might hit that 20-day limit, we need to push things up. RUN ON SUN WILL NOT GUARANTEE NEM 2.0 FOR ANY APPLICATION SUBMITTED AFTER MARCH 15! (The Ides of March indeed!)

This is a terrible way to run a business, but we have no control over the arbitrary nonsense coming from SCE. Please plan accordingly!

Battle to Save Rooftop Solar - Act Now!

Readers of this blog are well aware of the fight being waged before the California Public Utilities Commission (CPUC) as we first wrote about this back in February!  Now we are entering the final stretch in this fight, and quite frankly, we are losing. 

Why, you ask?  How can we be losing the battle to preserve your right to put solar on your home or business, when everybody loves that idea?  The answer is easy: the opposing forces - we are talking about you here, Southern California Edison - have nearly infinitely more money than we do, and they are spending it like crazy.  So how do we possibly fight back?

With you.  And tens of thousands of other folks just like you.

The California Solar and Storage Association (CALSSA) - our trade association - is fighting hard to preserve the value of the investment made by past solar clients, and those in the future.  They have created an audacious goal: generate 200,000 public comments by November 20!  Here’s how CALSSA framed the fight:

“If the broad light of day could be let in upon men’s actions, it would purify them as the sun disinfects” – 1891, Louis Brandeis, US Supreme Court Justice

In 2015, the pro-solar coalition submitted 130,000 public comments to the CPUC on the NEM-2 decision. Today, as we near the homestretch in the NEM-3 proceeding, the headwinds are greater and the opposition better organized. Therefore, we are launching a campaign today to reach our goal of generating two hundred thousand public comments by November 20. Reaching this goal would break the record for the greatest number of public comments received by a state agency in history – previously set by solar advocates in 2015. Simply put, two hundred thousand is a number that the CPUC and the governor simply can’t ignore. It is the sunshine that is needed to fight against the corrupting influence of SCE and the other utilities

We cannot afford anyone sitting on the sidelines.  If you own a solar power system, the value of your investment is at stake.  If you realize that rooftop solar is a key piece in how we reduce carbon emissions to combat climate change, that goal is under attack!

It’s easy to join the fight: Mash that button below and tell the CPUC to side with solar consumers and not with the utilities!

SCE Just Hiked Their Rates - Here's What That Means For You!

While you weren’t watching, SCE - the same SCE that is trying to kill off rooftop solar - just raised their Time-of-Use rates for residential customers. We will break down the increase and show you what it might mean for a couple of potential solar clients.

What are Time-of-Use Rates?

Time-of-Use (or TOU) rates are exactly what they sound like: a rate structure where how much you pay for energy is tied to when you use that energy.  (We wrote a lengthy blog post explaining the differences between TOU rates and Tiered rates, in gory detail!) 

The most common TOU rate for SCE’s residential customers is titled TOU-D, with the 4-9 p.m. window having the highest rates overall.  Compared to a tiered rate -  where your monthly bill is divided into steps based on the volume of energy that you use, with each volumetric step, or tier, bringing you a higher rate - a TOU rate does not increase on volume but on the time of day.  As a result, rates during peak periods can be 50% or more higher than the lowest periods.  Of course, that peak period - either 4-9 or 5-8 with SCE - corresponds to when people generally use the most energy!  Gotcha!!! (Those rate differentials are what provide the economic benefit of adding storage, and make simple strategies - like delaying the dishwasher or EV charging until out of peak rates - effective at saving money.)

How is SCE’s TOU Rate Changing?

Needless to say, SCE’s rates are very complex, with the energy charge being comprised of some eleven different components!  I will spare you those distressing details and just focus on the overall energy charge and how it has changed, as shown in this table:

SCE rate change as of 2/1/2021

SCE’s TOU-D Rate change for the 4-9 p.m. option.

On average, we see that rates here have increased between 3.67 and 3.80% over the prior rate, but there are some special gifts to solar customers buried in the rates.  When the Net Metering rules were changed a few years ago, it introduced the concept of Non-Bypassable Charges (or NBCs) - components of the rate structure that solar customers paid for every killowatt hour pulled from the grid, even if that same kWh was netted back by energy exported to the grid.  Far and away the largest NBC is the Public Purpose Programs charge, and in this rate increase it jumped from 1.323¢/kWh to 1.622¢/kWh - a whopping 22.6% increase! 

Another fun fact for SCE customers who have endured so called public-safety shutdowns, is that they are paying 0.6¢/kWh toward the “wildfire fund charge"!  That’s right, SCE’s customers are helping to pay for an insurance fund against wildfires caused by SCE, PG&E, and SDG&E - now isn’t that almost enough to get one hot enough to, well, burn!

Use Case Impacts

We decided to examine how potential clients would see their bills, and potential savings, change under the new rate structure.  As always, we made use of the wonderful tool Energy Toolbase to do our calculations. 

Average user comparison Our first example is a pretty average user in the Run on Sun service area, consuming approximately 30 kWh of energy per day, pre-solar.  Under the old TOU rate their annual bill pre-solar was $2,946, but under the new rate (including things like utility user taxes, etc.) their bill would go up by nearly 5%, an extra $144 for the year.  However, their post-solar savings also increase, by 5.42% or an extra $143 per year.  For this average user, adding solar ended up being a nearly perfect hedge against the SCE rate increase!

Heavy consumption use caseOur second user does not fare quite as well.  This is a significantly larger user, consuming more than 50 kWh/day.  Their pre-solar bill increases by 4.29%, or $228. Unfortunately, while their overall savings increases, it is not as dramatic as it is for the smaller user, reducing the differential from $228 to $92, compared to reducing it to just $1 for the average user.

Bottom line - adding solar helps hedge against rate increases, and as energy costs get higher, your annual savings will increase!

Meanwhile, SCE is Trying to Kill Rooftop Solar

It is one thing for SCE to be seeking, and getting, rate increases from the CPUC - that is their business model.  It is quite another thing for them to try and gut the value of net metering, thereby eliminating the economic value of adding solar - but that is precisely what they are trying to do!  We are fighting back, starting with a signature campaign targeted at a petition to Governor Newsom

There will be lots more to do in the coming days to fight against SCE’s attack on solar, but for now there is something simple that you can do - mash that button below and go sign the petition!

My Electric Bill is So High! Will Solar Help? Part 1: How High is High?

We hear it all the time: “My electric bill is so high, I just want to stick it to [insert name of utility here]!  Can solar help?” Now we are in the business of selling and installing solar, so our preferred answer is, “Of Course!"  But that is not always the answer we end up giving.  So Part 1 of this three-part series focuses on that electric bill to answer a few questions first: 1) How high is it? 2) What can you do to make it lower - pre-solar? And 3) Is your home even a good candidate for going solar?  Let’s look at each in turn…

How High is High?

Ask most any consumer how high their electric bill is and they will all pretty much tell you – too high!  So let’s recognize a few things at the start: if you are a PWP or DWP customer, your electric bills will be lower than your compatriots sufferi, er, living, in SCE territory.  SCE bills monthly, whereas PWP and DWP bill (roughly) every two months.  Most non-solar, residential customers are on a tiered rate structure - that is, the more you use, the more you pay for what you are using.  That said, not all tiered rates are alike: SCE has a true, three-tier rate structure where the cost increases in each subsequent tier, whereas PWP has a bizarre structure where the “highest” tier is actually cheaper than the middle tier!  (I wonder how many PWP customers realize that perverse incentive?) 

Taken together, what can you say about how high is high?  We would break it down roughly this way:

  • $100 per month or less - Solar is probably not going to pencil out for you.  While there are many reasons to go solar besides the economic ones, if your bill is this low, saving money is not going to justify solar.

  • $100 to $300 per month – depending on the other factors discussed below, bills in this range are more likely to have a strong economic justification, particularly in DWP territory, where a small rebate remains to help lower your out-of-pocket cost.

  • $300 or more per month – Solar is exactly what you need!  The higher your bill, the more solar makes sense.  (We had a client with bills that averaged over $1,000 per month!  His payback was four and a half years!)

To illustrate how and why that works, let’s look at the modeling that goes into sizing your system.  (For this analysis we made use of Energy Toolbase, one of the most sophisticated tools available for modeling the performance of PV systems and producing comprehensive, authoritative and transparent solar proposals.)  We created three different usage profiles corresponding to the categories set forth above.  All were SCE customers under the current Domestic rate structure in region 9 (i.e., Altadena).  The first had usage such that their average bill was under $100/month.  The second had bills between $200 and $300/month, and the third had bill in excess of $450/month.  In each case, summer usage was higher than the rest of the year.

Total electric bill savings, middle-use case

Energy Toolbase allows an installer to run multiple simulations of total bill savings based on the size of the system to be installed.  On the right is that output for our middle-case client.  It’s a little hard to see in the small version of the graph (click on it for larger), but the light green line (which represents the savings under the new, SCE-forced rate structure) levels off at 7.9 kW.  That inflection point means that a system sized larger than that is no longer providing a full economic benefit to the client.

We performed similar analyses for the other two use cases to determine the optimal system size, and to then determine their savings and payback.  Here are our results:

Payback as a function of system size

As system size increases, even without assuming any improvement in price based on economy of scale (the system price in each case is $4.00/Watt), it is clear that larger systems have significantly greater return on investment over the life of the system.  If your bills fall into that third use case, you are going to benefit greatly by adding solar.  But in that first use case, not so much.

What can you do to make your bills lower – before adding solar?

However, even if your use case makes sense, it is important to consider some low-hanging fruit before plunking down thousands of dollars on a solar power system.  The two most obvious candidates for investment are pool pumps and air conditioning systems. 

Pool Pumps

Older pool pumps tend to have single speed motors, which means that they draw the same amount of energy all the time.  But harken back to your elementary school science classes: a body at rest tends to stay at rest; a body in motion tends to stay in motion.  (Thank you, Isaac Newton!)  What’s that got to do with pool pumps?  Well, all that water in your pool has  a lot of mass and when it is just sitting there it takes a great deal of energy to get it moving - it’s a big body at rest!  But once you get it moving, it is relatively easy to keep it moving, so you need to expend a lot less energy to do so. 

Single-speed pool pump motors don’t get that, and they just keep pumping as hard as they can the entire time they are on.  That is wasteful, and expensive.  A variable-speed pump, on the other hand, embraces the eternal wisdom of Sir Newton, and throttles down over time.  That saves energy, and thus money.  Even better, utilities like SCE will give you a rebate (from SCE that is $200!) toward the cost of installing a variable-speed pool pump.

Updated A/C

The other big opportunity for savings is in an updated A/C system.  Newer systems are significantly more efficient out-of-the-box, and as older systems age, their efficiency decreases, meaning they are costing you more to operate.

Other Savings Opportunities

You don’t really have an old refrigerator running in your garage, do you?  If it is old, it is inefficient, and you’ve just put it in the hottest part of your home (short of the attic) so it has to work really hard to keep that case of beer cold.  Either ditch it altogether, or only run it when that party is about to happen!

How old is your thermostat?  Does it even work, or do you just use it as an on/off switch?  New, smart thermostats can save you money - and there is likely a rebate there, too!

How good a candidate is your home for solar?

Ok, your use case is compelling, even after harvesting all that luscious, low-hanging fruit.  So is it now certain that solar will help?  Um, maybe.  How good of a candidate is your home for solar?

We have written about this at length before, for example here and here.  If you have lots of shading, your house will not be a good candidate – you don’t want to be the owner of a system installed under a tree!

But other issues can change the value proposition for installing solar.  For example, your electrical service might be ancient and undersized, requiring you to spend additional money to upgrade to a newer, larger service.  If you are installing a relatively large PV system, that is a relatively small increase, but on our small use case, upgrading your service panel can add 10 to 15% to the total cost.

Other factors that are not show-stoppers but which increase costs are second-story and/or steeply pitched roofs (both of which just make the labor costs higher because the work goes slower), roofs other than composition shingles, service panels located far from where the array needs to go (like the array on a detached garage but the service panel in on the side of the house with a concrete driveway in between).

How can you know for sure?  Simple, have a professional installer come out and do a proper site evaluation.  So how do you find such a person?  Ah, that is the subject of Part 2: How Do I Find Someone to Trust?

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!
