Sources please! There's more to retail than just billing. Off the top of my head there's advertising, acquisition of customers, creation of plans/pricing/campaigns, getting consumption information (which in New Zealand is from 50+ local distribution companies, each with their own formats), there's purchasing from the wholesale market in such a way that you're not losing money all the time, there's setting up a call centre to service those customers, there's meeting regulatory requirements such as a government disputes process, those are just the ones I can think of sitting here. And I'm not saying that those costs should be massive, I'm just saying those costs exist. Someone must pay for them. Considering I've observed that the margin on retail electricity customers is not much (like $2K of customer lifetime value over 10 years), it's not like in New Zealand electricity companies are rolling around in cash from profit per customer, it's really just a volume game (the company I worked for had 430,000 retail customers). BTW, the value chain in energy from generation to transmission to meter to cash is full of lots of participants. In New Zealand, the generator, wholesaler, retailer, national distributor, and local distributor are all separate entities. To say "Utilities ... are overestimating their stranded costs to the extent that they don't count the increase in the efficiency of their ability to serve load" ignores the reality of this value chain. At best, this really only benefits the local distributor.

I was coming at it from a US perspective. In the US retail is still dominated by natural monopolies with service areas and captured customers so those costs are low. There is a huge push toward the kind of retail competition you are talking about of course, however, while the growth in the sector is huge the vast majority of customers still behave as captives. https://ei.haas.berkeley.edu/research/papers/WP252.pdf https://ei.haas.berkeley.edu/research/papers/WP252.pdf As for the value chain you are right that I am simplifying but we are on an internet comment board not writing a white paper. However, the simplification doesn't matter. Whether it is vertically integrated utilities or deregulated and unbundled electricity service, the point still stands that stranded costs are overestimated to the extent that they don't account for the fact the netmetered kWhs tend to be high value, are resold at retail, and do not have to be purchased or delivered by the seller. Adding more middleman or more costs just adds accounting wrinkles (and which I think are inappropriate for the forum). If your point is that the harm is caused by a reduction in aggregate demand then that is a completely different argument.

>Sources please! Asking for sources for a rebuttal to your opinion is a bit underhanded given that you provided none to backup your claim. And no, your comment isn't more than an opinion because you've worked in the industry. An informed opinion sure but asking for someone to provide sources to their argument would be a bit hypocritical unless you are going to step up as well.

  I enjoy a good internet discussion! So the topic of debate is whether its fair to charge a retail price for solar buybacks, or a wholesale price. I argued that a retail price is unfair, because energy utilities have a bunch of retail costs, of which billing is one of. The counter argument is that billing is a minute component of the retail cost. You've suggested that I have an informed opinion, but need sources to back up my argument. Contact Energy have a management paper that discusses energy costs. A definition of Netback from Contact Energy (2015) is: Netback is calculated by deducting the network, meter, levy and cost to serve costs from customer tariffs. This enables the performance of the retail channels to be measured without using an energy cost. The netback is meant to cover, inter alia, the cost of energy, capital return, risk margin and a retail margin. Cost of Energy was $994M, while Cost of Transmission and Metering was $621M, and Cost to Serve (such as billing) was $118M for Contact Energy for the year ending 30 June 2015 (Contact Energy, 2015). The remainder, as EBITDAF was $484M. As you can see, $118M for Cost to Serve is 11.8% of the Cost of Energy. This doesn't change with solar buybacks. The cost of energy is from a different source (your personal solar panels), but there's still costs of transmission and metering, cost to serve, and depending on the utility you connect to, some sort of EBITDAF (unless they're a not for profit). So that's $0 (your solar panels) + $621M (transmission/metering) + $118M (retail/billing) + $484M (earnings before income, tax, depreciation, amortisation, and changes in fair value of financial instruments). Do check out McNicol (2013) for an interesting article on this. tl;dr - Electricity networks are expensive, and the cost of energy is about half the total costs of running the system. Who pays for that, if the utility has to pay the retail rate to you because you're using solar panels? References: Contact Energy. (2015).
