New IL Energy Bill and Solar PV are huge Bonus to this group!!

[Rex Irby]

IL (ComEd and Ameren) will be paying large dollars for solar Renewable energy credits for total production of "Distributed Generation" under 2 MW.

They will pay up front for 5 years of production to offset the upfront capital cost of us getting into Solar PV.  This means potentially from historical's - 5 years time $180-$220 per MW SREC of ALL production.

Example:  A  RTP customer who averages 750 KW per month would need a solar system of:  750 kWh/m * 12 months / 365 days divided by 4.33 solar hours per day divided by .80 (20% system total losses).

850 * 12 /365 /4.33 / .8 /1,000 watt/KW = 8 KW PV system

Average cost per final installed watt believe it or not is about 2.87 to 3.00 watt.  Total system cost before incentives and federal tax credits is $24,000

Less federal tax credit and this nets to $16,800

Annual kWh production in Chicago for this PV system would be 10,533 kWh - using pvwatts.nrel.gov

Upfront SREC value to reduce capital cost is 5 years times 10.533MW  * $180 conservative = $9,480

This brings the system to $7,320

Financing this system balance at 4.5% for 5 years (60 months) comes to monthly payment of $136/month

If you sell the majority (60-70%) of your net generated electricity from 9am -5pm every day on real time price back to ComEd at a fixed component amount of .0485 plus real time energy charge of .0497 - you can get a credit on your bill for selling  = average $48 - $93 / month.

This brings the financing payment down to $136- 48 or  93 =  $43  - $88 /m

Reduction of your bill will also occur in the 3-6 solar window since you will have no ComEd usage on the bill during the bright daylight hours.  Meaning NO AC electricity cost that could easily knock off 20% of average annual bill.  (deduct another $19-20)  Net Solar PV system monthly payment is now $23-68 / month. 

Also highly reduces capacity obligation charges and exposure.

After 60 months you should be able to get a zero bill to cover all fixed non usage fees on your bill for selling back. And practically never pay for electricity again!!

You cannot cash out the credit balance - its lost every year.

This selling back of net generated electricity at these unheard of rates is only applicable to RTP customers!!

Where can I find more hard details on this (apparently new) program? My house isn't ideal for solar (East/West facing roof) but if the credits are high enough, the loss off efficiency can be mitigated.

You can put solar on pole mounts or awnings to the south side of the house.  That is what I am planning down the road.

[Jerry Fountain]

Sadly, no room for either. Plenty of roof space, just a North/South running open gable architecture.

How about awning  and/ or car port overhang 

- my drive way to the back of property detached garage runs next too house on south open gable roof end and I can put panels as awnings above the first level windows and possibly take them two rows with the narrow end facing the house.

[Ryan Ziolko]

Thanks for the info!  I've been following FEJA too.  My house has an unobstructed (thanks microburst!) E/W gabled roof.  Currently looking at 6KW system, but there is plenty of room for more.  I think I'm going to pull the panels on the West side, to catch the summer afternoon peaks.

My understanding of RRTP and net metering is that ComEd credits/charges you at the realtime rate when feeding/drawing from the grid, but that it's contained to a month.  The rep I spoke to said the credits don't carry over (and they'll never cut you a check) month to month...  unlike net metering on the fixed rate plan.

RRTP and net metering allows you to play the spread between day and night prices.  If you can push your loads to the evenings, you can get away with a fairly small PV system and still have an essentially $0/month bill (not sure about the metering and other random charges).

I have been following some of the info on solar panels.  Who is the rep you contacted?  Someone from RRTP? 

[Greg Ward]

I have homes in both Hawaii and Illinois.  In Hawaii they purposely DO NOT increase the value of your home when you have a solar system as a further incentive to installing solar electric or even solar hot water.  Here in Illinois the opposite is true.  Since Illinois primarily gets it's revenue from home and business property taxes I doubt if they will ever want to change that policy - unless they really cared about energy diversity in our communities.

[Greg Ward]

I finally got my Smart Meter installed last week which replaced my hourly time of day rate meter. 

Are there any products that will allow me to see my power usage in real time? If I have to buy some kind of hardware interface let me know.  I'm disappointed that the ComEd Smart Meter site and flyer that the installer left behind does not mention anything regarding my question above. 

Also the ComEd online usage tools/graphs are NOT real time and leg about a week.  Very disappointed after waiting years to get the new meter.  :(

Rainforest Eagle-200 Home energy Monitor - Amazon - $100 total.

Not pushing this - FYI - I have had home energy monitoring for 10 years now but this is a cake walk compared to mine that is getting old.  This unit will likely replace mine.

What does it do - no electrician needed - easier than Apple TV

.

1.  Plug it up - spend $11 dollars a year on electricity.

2,  connect to your wifi or ethernet cable next to the router is the easist

3.  Quickstart guide from RainForest Automation here

4. Register device on ComEd portal to be compliant - MAC address, cloud ID, install code.

5.  Start monitoring

 Through its web portal or your phone you can see within seconds the entire house's electricity consumption.  Great audit tool!

It will pay for itself pretty quick once you identify some large 24 * 365 energy hogs that you can take down with a power strip.

I have the Rainforest Automation EMU-2 connected to a Raspberry Pi, publishing our demand to an MQTT broker.  I "repurposed" a Nook Simple Touch (with a front-lit E-Ink screen) as a display of the current hourly average price and our current usage.  It hangs in our kitchen, and after you look at it often enough, it's easy to tell when someone (my kids) left a set of lights on somewhere.

The EMU-2 is a nice piece of hardware, and pretty easy to communicate with over USB, though they have a pretty goofy XML-based protocol.

Hi Shiela,

The RRTP folks pointed me to netmetering@comed.com.  You get to pick April or October for when your credits for excess generation expire.

Regards,

Ryan

Didn't mean to resurrect an old thread, but I didn't see any new threads on solar with RRTP.   Wondering what people here have done and if they can share their story.   

Long time customer of RRTP - just hit 12 years last month.   Total savings of $1,400 or 21.3%.  

Thanks.

I installed my purchased solar system a year ago, and I just completed my 12th month on RRTP net metering rate.  My system is 6.5 kW and the installation cost was $2.80/watt. The 30% federal tax credit and the IL ABP SREC payments covered 70% of the installation cost. I expect that I will completely pay for the system after about 7 years.

The RRTP program has not been able to update their savings calculations to account for solar net metering customers.  When I log on to the hourly pricing site i have had the following message since last October:

"We are updating the account experience for you and other customers who have renewable generation. In the past, the savings information presented here was not properly accounting for the energy your home was producing. We will send you an email when your monthly savings information is available here. In the meantime, you can access your hourly usage data (in-channel data only) by visiting the “MY GRAPHS” page."

That being said, I have done my own savings calculations and I have found that the RTP has definitely saved more than the standard net metering. Each month I calculate what my RRTP bill would have been had I not installed solar. In the first 12 month I have calculated that my solar savings was just over $680.  It will be interesting to see how my calculation compare once the hourly pricing site updates their savings calculations.

One thing that I am now seeing in Year 2 is the reduction in capacity charge which will add to my savings. My PLC is 0.63 kW for this year, and had I not installed solar it would have been 2.24 kW. So starting with my June bill I have seen the significant savings on my capacity charge, and my annual savings should increase by about $150/yr.

My solar system was a good investment and I am glad I got it installed when I did since the federal tax credit is phasing out and the SREC payments have come down since I was able to get into the program in block 1.

Thanks, this is helpful.  

Your numbers are quite impressive.  Given the block program, federal incentive, RRTP, and net metering, it seems like a win-win situation.   Hope they can fix the site issue.

Did ComEd limit you on the size of your system based on your last 12 months of usage plus 10%?

Yes, since April 2018 they've been much stricter, and have taken steps to formalize the 110% rule (which was their interpretation of the "offset usage" wording in the IL Public Utilities Act).

For something that'll be on your roof generating electricity for 20+ years, it's not ideal to only look at your trailing 12 months of usage.  I tried to explain I was planning for what my usage will be in the next few years.  We had an order for a EV, and are looking into going all electric (hopefully with a GSHP, but that's been slow going).  After the battle I had to get net metering, I've encouraged friends to "adjust" their usage in the year leading up to their solar install.  I know it sounds ridiculous, but even though energy efficiency is improving, more things are going electric, so usage continues to rise.  

Post mid-2018 ComEd started catching the 110% issue earlier (like during the application for interconnect).  My panels were already installed when my application was denied.  Catching it earlier is helpful, but there needs to be some provision of usage growth.  They'll never cut you a check, so worst case they end up with some "free" electricity on the grid that you don't get compensated for.  Maybe not ideal for the generation side of the business.

Any idea what they would do for a new Construction house?

If there is no 12 month usage... 

[Ryan]

They might be able to use your “class” average.  You class is defined by the size of your house and if you are all electric, perhaps other attributes.  You can reach out directly to the net metering department to clarify.

Ryan
