The real interesting thing here is all Nem solar contracts are grandfathered... But... when the battery added to the solar system, net metering is replaced with aggregation compensation through Solarcity. Thus, every grandfathered system at that point no longer is under nem. Utilities no longer have to pay those retail rates to these 20 year contracts that they are saying is shifting too much cost.
So, net metering naturally goes away as installs solar+storage grow. It's the market system actually working. As a result, the utilities take that long term payment schedule off their books, replace it with demand response which saves money on peaker plant deployment as well as accelerates achievement of epa carbon reduction regulation as well as state renewable goals.
In effect, maintaining net metering at retail actually accelerates the end of net metering and catapults utilities toward grid modernization within the new grid a service model.

Solarcity needs to to not run out of cash for operations. They don't have to finance all of each contract because they have a profit margin. They probably need to finance 3/4 of each contract, which is where the 20% comes from.
That's why understanding the true profitability of the average sale each quarter is critical. If they are truly selling profitable business to creditworthy customers, then financing should not be a problem.

Foghat - Forgive my lack of knowledge on this, as I have been following this thread for some time, but not posting, and some of the statements on hear seem to rely on some "institutional knowledge" that I don't have.
First, you refer to all the net metering contracts being "grandfathered". I understand the concept, but in practical use to the consumer, what does that really mean? Once the utility installs a net metering device, is that meter now stuck forever? Can they never remove it? With permitting regulations, grandfathering prevents owners of existing facilities having to upgrade every time the standards change. However, when a utility permits someone to utilize a particular service, are they required to continue providing that service forever? It seems that it would vary by jurisdiction, but I don't know.
Second, if SCTY expands solar+battery installs, then how does that catapult utilities to grid modernization? Aren't they getting less income from their grid, so therefore less incentive to put more capital into an asset that is returning less all the time? Again, I assume I am missing something that will make it obvious.
That's right. Imagine SolarCity approaching a utility saying, "Hey, we've got 50,000 NEM customers in common with 250MW of solar. We'd like to install 100MW of Powerwalls for 400MW of storage all aggregated for grid dispatch. How can we make this happen?"
Such a deal would be worth several new peak power plants plus off load the obligation of NEM.
The cool thing for SolarCity investors is that such a deal would leverage the existing customer base to add business and long term cashflow. This is incremental to NRV and would have minimal sales cost. Most customers would likely be delighted to participate because it gives them backup power at little to no cost.
This is one way that SolarCity can create incremental value without installing more panels. We simply do not know the details of the new strategy. It is possible that SolarCity could pull this sort of thing off in 2016 and it would be worth installing fewer MW solar to do it. From an ITC perspective, it would be very good to do this in 2016 before the stepdown. I think the main consideration here is how much Gigafactory output they can get their hands on.
grandfathering the net metering rates that applied at time of contract. So, if net metering changes from retail rate to less then retail rate, grandfathered systems still get retail rate. And this applies if the net metering rate goes down again. For the life of the contract they get that retail rate.
the incentive for a Solarcity customer to add storage has many benefits for them as consumer:back up, communication with thermostats, dishwashers, air conditioners, connected home efficiencies, etc... As well as a 50/50 aggregation share which all translates into a lower cost per kWh then they are paying right now. The value proposition is competing for a consumer. The demand will be robust given basically no saturation of the market, a very big trillion dollar market. Now, the utilities have incentives to use aggregated storage for demand response. The more solar+storage homes, the greater demand response capability. In addition, eps and state goals will be met with actual retail rates going down. Win win all around. Now the rub is exactly as you say, the vast majority of utility model does not incentivize reducing capital costs because they get a cost plus compensation. However the purpose of oversight by commissions and other governing bodies is to protect consumers from the natural tendencies of monopolies as well as oversee there cost structure to provide reliable electricity to the consumer. The numbers start to become to obvious to support regulatory capture and the system is forced to change. This is the reality of solar+storage on the current system. It just makes sense on so many levels it's hard to spin and cover up to protect entrenched interests. As we are seeing now, maximum effort is being leveraged to spin it and delay, but he numbers don't behave as they want and everyone can see it.
Again, nem promotes the installation of solar. More solar, means greater scale, greater scale leads to cheaper solar and batteries, cheaper solar and batteries lead to cheaper retail electricity and accelerated transition to a renewable low carbon emitting grid system which meets state and federal emission goals sooner.
The irony is that actually maintaining net metering at retail prices, accelerates the elimination of nem completely. No 20 year grandfathered credits to have to pay. Gone forever as batteries are coupled with the solar systems old and new. As some utilities are trying to add fees and reduce net metering credit, they are only preventing the market from taking hold and eliminating net metering off their books in addition, decelerating distributed demand response increasing massive long term capital investments which will only continue retail price inflation on consumers and missing carbon emission mandates.
as the benefits mount, light is shined on the solution and utilities will be obligated to comply which is the catapult point since the market will respond swiftly and efficiently to produce the solar+storage solution at the cost per kWh consumers desire.

thats right Lyndon said once they have the customer base, acquisition costs slim down to utility levels... Like less then $100/per customer... Imagine that, from 2000-3000 today to 100. That cost structure is wildly complelling and hard to deny given current centralized monoplistic system that has only increased retail prices since its inception.
i did. I also think you have to add in fuel costs,maintenance, retirement costs for the life of the peaker plant. In addition, they only run it a handful of time, but that resource needs to always be at the ready, so what is the actual cost per unit of energy used on the grid.The only sales cost I envision with this deal is contacting existing customers to see if they would like to participate in the program getting a battery for very low cost.
Did you see the calculation I added on the value of such a program to the utility? See above post.

What are the maintenance costs of the distributed array of solar panels and batteries spread across millions of homes? I'm sure it would be very low, as solar systems are pretty "hands-off," but there have to be some costs to trees falling on roofs, windstorms, leaking roofs requiring solar panel removal, batteries reaching the end of their lives, Lucy runs into the powerwall in the garage, etc. Is there any data out there to quantify any of that?
..... Gigafactory is a significant piece here. Elon has stated that he sees significant cost savings at full production levels and those are expected in late 2017 through 2020 time frame.
Thanks for the insight. Like everyone, I have heard a ton about the gigafactory, but that opens some more questions for me. Based on the research I have done, it seems that Tesla is using existing Panasonic technology for their batteries. Although I understand their batteries are somewhat "special", it doesn't seem there are any step function type improvements in Tesla batteries. Given that Panasonic (and others) already produce large volumes of batteries using the most modern production techniques, what is Tesla planning to do to make such drastic reductions in battery cost? If you have the same raw material inputs using the same manufacturing technology to make what seems to be only a slightly "premium" product, how do you save so much money just by putting up a spectacularly huge building to hold your whole project in? I just haven't been able to find anything that differentiates them as far as being able to change how batteries are produced. Obviously there are a lot of big investors who have been sold on it, and I know they do their due diligence, but for a publicly traded company, where's the magic that explains how Tesla and SCTY are going to have these drastically reduced battery costs?
