It's not so much about making people curb their usage, as making it so the appliance does. A few weeks ago I installed some ludicrous 84 inch 4K display in a business, but it only draws 196 watts peak. You could easily draw 200 watts from an old time 19 inch all-vacuum tube set back in the day, or a larger CRT later on. Meanwhile normal people get mere 50 inch sets that only draw like 100 watts. Or you know houses that used to be full of 60 watt incandescents, and now every lamp was replaced by a cheap 7 watt LED. Fridges that use way less power, houses that bother to have insulation, et cetera. OwlFancier posted:How do you put energy back into the grid without a powerplant sized transformer?

Kaal posted:Liberal political organizations have been slow to respond to this oil industry talking point, and it's been spreading like wildfire in Republican states that are hostile to environmentalism. There's a real need to develop the idea that home solar represents a direct investment in the community energy grid, which reduces costs for everyone by expanding the generation base and increasing line efficiency. Investment in home solar reduces the need for costly infrastructure expansion that has to be paid for via bank loans and rate increases. These rooftop projects also help develop the local economy by employing local small businesses, as opposed to large out-of-state corporations that build and fuel the oil and gas plants. This fiscal viewpoint isn't being advocated sufficiently, particularly in conservative areas that are more interested in the bottom-line than climate concerns. Solar power generated at a customer level requires increased distribution infrastructure costs if penetration increases to a significant level. Generally the grid needs to support time of use metering for customer installations, additional potential metering infrastructure to help keep voltage in check if significant generation exists on the distribution feeder and if enough generation exists the potential for switching/protection upgrades could become required to verify that faults are cleared properly. Also, since peak solar production generally leads peak demand by an hour to two hours, there is no savings in distribution equipment sizing and if the local generation exceeds local demand additional work may need to be done to support the export of energy to other load centers. Some of these points are also things that will generally happen to the grid as technology and price of those features comes done but it's rather disingenuous to claim that rooftop PV makes the grid cheaper to build or maintain. Kaal posted:I'd be happy to hear more about those concerns, if you're able to find those kinds of presentations and relate them to us.

I think I have enough surplus credits to keep the thermostat at 58F until fall. My poo poo Republican state is going to push legislation through that would make solar not worth it for most people. Arglebargle III posted:If you ever needed proof that human people are not the Republican constituency. The personal solar issue is about 90% about loving over people who don't own solar, only about 10% about loving over the electric company. You're cost shifting and adding inefficient capacity, not lowering costs. A somewhat simplified example: Consider a traditional utility with 2000 MW of peak load that happens between 6 pm and 9 pm. They charge fuel at cost (regularly updated through regulatory procedures) and earn maybe 9% regulated profit on their capital infrastructure (transmission and distribution infrastructure plus the generation assets they own). Now let's say a whole lot of customers install solar panels, enough to produce 200 MW of energy during the day and saving them personally a whole lot of money. How much does this hurt the electric company's profits and how much does it reduce their costs? Essentially zero impact on profit, but costs go up slightly. All of that 2000 MW of generation capacity that already existed is still necessary at night, so you can't retire any of it. All of the savings during the day are fuel for idled peaking plants (which will still run at night), which the company doesn't make or lose any money on. The electric company has to spend a little more money and time hooking up and dealing with the solar generating customers, but it's not significant and ideally the solar customers pay for that themselves. So what happens to the customers who don't own solar panels? Their rates go up enough to support the lost revenue from the solar customers. All of those unchanged capital costs are built into usage per MW, and the solar customers aren't using as many MW, so the capital cost per MW of other customers has to climb to compensate. The electric company profit is unchanged, the solar customers save money, the other customer spend more money, everyone hates the electric company. Now in aggregate that solar has some ability to retire capacity. For generator maintenance that can be accomplished in a few hours during the day, you can substitute solar for redundant gas peakers to cover that downtime. But until storage become economical you can't retire any of your generation necessary for peak load, which happens at night. You can plan for this by the utility building or contracting for its own solar capacity, but ad hoc individuals on short term contracts don't help with required reliability capacity planning on 20 year horizons. Bad state incentives implementing avoided costs for qualifying facilities under PURPA have resulted in huge overcapacity being built by small (<80 MW) solar facilities in California and Idaho that they are constantly curtailing. Idaho Power has something like 1800 MW of peak load and 1300 of mandatory solar purchases and crushing Idaho rate payers. This is driving rapid integration of outlying states with CAISO's energy imbalance market, as California desperately tries to shift this useless energy to the east and take advantage of those areas hitting their peak load while California still has some sunshine. Idaho is still going to be hosed, because there's no significant load to their east they can transmit it to.

This is all wrong. Kaal posted:But the utility takes that power and sells it to someone else, right? So it's not really zero profit at all. By taking on local power generation, home solar actually reduces production costs for the utility - participating in the public good and driving down rates by increasing overall supply and reducing the demand on the utility. Home solar projects are a net benefit to everyone on the electric grid, including the utility. Each installation represents, in the final sense, a reduced need for costly infrastructure bonds and rate increases. This, too. Incidentally, zero is a common price for (small) energy sales between balancing areas. It's often cheaper (or has reliability impacts) to give away your useless energy for nothing than to shut off or curtail its source. If you need to meet 50 MW more of load and you have to start up a 73 MW minimum generator to meet it, you might as well give that surplus 23 MW away to to a neighboring BA if they're willing to take it rather than have too much power on your system. You'll hopefully catch it from the other direction enough to offset. Syzygy Stardust fucked around with this message at 15:46 on Aug 10, 2017 |

All a grid-tie inverter needs to do it turn your solar DC in to AC that matches the voltage and phase of what's coming into your house, the transformers already in the grid do the rest.

OwlFancier posted:I mean, doesn't the power grid run on extremely high voltage to minimize transmission loss which is then stepped down for domestic use? Transformers work both ways. So the small pole top or pad mount transformer can step up voltage from your 120v solar source up to 12kV distribution voltages, and so on. When it is a small amount on a distribution feeder, the utility doesn't care that much. If everyone starts putting in solar/wind generators in their backyard, then other problems develop. The protection systems for distribution lines typically assume that there is only load downstream from them. If there is enough generation on that distribution line, the protection equipment may not operate correctly for a fault, or may incorrectly de-energize the line when there is not a fault. Not to mention the fact that if the generation is not installed with proper protection, they can backfeed the distribution line when it is supposed to be off due to a fault. That has the potential to damage your devices, your neighbors electronics, or get a utility worker killed. This circles back to the fact that end user generation has costs to the utility that the average person has no clue about. Add to this the fact that residential electricity is the most expensive rate that a utility gets to charge. So paying an end user for excess generation isn't in a utility's best interest. At best they can resell it at 0 revenue. At worst it is used to offset much cheaper generation from large scale generators.

There's also the problem that on a cold winter day, the town still needs all the power it usually does, and the electric company has to supply it. So they still have the capital costs of building and maintaining full generating capacity, without being able to derive any profit from it much of the time. Distributed generation certainly can work, it's just not a good fit for our system in its current form. It will take a full rethink and redesign of everything in the system. Whether there is the political and economic will to do that is another matter.

The grid upgrades you're talking about are paid for by the home solar installation because they're obviously critical to being able to achieve basic functionality. The idea that this investment into the grid should be ignored because it directly benefits the owner makes no sense at all - they're paying for the upgrade rather than that money coming out of the rate payments. It's clearly saving money for consumers as a whole, particularly because these improvements are happening regardless of the development of home solar. quote:The utility losses all the energy lost in the distribution system and has to pay for the equipment used to transmit the solar energy, pay salaries for the technicians and operators, telecom, billing etc. You are correct, net metering isn't a zero profit setup for the utility; it's a negative profit.

The entire reason that California has shifted its peak pricing periods to the evening is because solar has taken such a significant bite out of the traditional daytime peak. They are single-handedly flattening out the power usage curves, which has meant that a lot of power plants have been able to be retired or never built in the first place. That is saving Californian rate payers a ton of money, though of course for-profit utilities like Edison don't really see that as a benefit. Rooftop solar is helping drive down costs to all consumers, reduce brownouts, develop the line infrastructure, etc., but this sort of obsolete thinking is focused entirely on the reduced need for baseline oil plants. Now there's a conversation to be had about how profitable these utility companies can really expect to be in an open market, but I'm not seeing a justification for the government thumbing the scale in order to deter solar installations. All these sorts of mandatory usage subsidies do is increase consumption and ensure a continued reliance on big, centralized infrastructure investment (along with the bonds and rate increases that go along with them).

The distributed solar debate sides are based on the two separate starting points: Either A, bottom up) When most people have solar power and rudimentary storage they cover the majority of their own power needs and the needs of their neighbors on each substation grid, and can pass excess in the neighborhood up into distribution to supply commercial and industrial customers. Or B, top down) A utility needs to control the means to produce enough to meet peak demand, or the ability to get supplied by larger utilities once local centralized supply is exceeded. In case A the grid supply's the means for distributed balancing, which it isn't designed for right now. The utility then must be the intermediator between all the parties involved (Which should just be autonomous billing, most of the time) and have a means for handling commercial and industrial demand fluctuations. In case B each home that has solar puts financial burden on the utility because the business model has been top down for decades, and that swings in clouds have a noticeable effect on the big customers of strip malls and industrial facilities. I think a good compromise policy decision would be that everyone needs to pay a minimum fee to be grid connected, and the utility capital infrastructure cost is subsidized by the taxes of the community while the utility gets the excess solar of each household for 'free'. The upfront cost for each homes solar is amortized over a few years by splitting the purchase cost between the homeowner and the utility by a negotiable fraction based on homeowner income, and over a few years the cost of the panels to the homeowner is paid back by the power they 'sell' back to the grid. That process may be tax credits, it may be subsidies given to the utility to pay the homeowner for their power. Each of these homes would need to meet basic safety requirements like having low voltage cutouts and transient protection so they can island themselves from the grid when needed. (As an aside I was reading a research paper where they talked about encoding a command into the 60Hz baseband on the HV side that could be picked up by the metering gear on the homes LV side to issue a command to disconnect from the grid until power was restored and the command was issued to reconnect. It was essentially a few bytes of 'command + MAC + error correction' that was passed at an incredibly low baud rate) I'm of the opinion that utilities need to adapt to the distributed grid system. There's a business model there and they just need to stop dragging rear end and get on it, its not like the grid infrastructure hasn't been hurting for upgrades for a decade anyway, use this as impetuous. The major utilities will still be needed to power cities and industrial centers that draw MW/acre, and centrallized solar/nuclear/NG peaker plants will be needed there. Another possibility is to combine those with centralized storage at the same sites so that the peaking is covered by storage that has been built up by distributed solar or constant running generators.

OwlFancier posted:I mean, I agree, full electrocommunism now, but I was more wondering why do they pay you for it currently? Well I think the justification is vested in the government's antitrust role. The utilities are the stewards of the electric lines infrastructure, but it was built for and by the public - often on the back of public bonds. There is a reasonable expectation that smaller players should be permitted access to that market, and that the public benefits by denying these utilities a monopoly of service. And of course it should be remembered that this energy is quickly resold to another consumer at market rates as well, far more efficiently than producing and transmitting that same energy across the state. It saves everyone money. And the proof is staring us right in the face, in the form of the peak usage periods flattening out to the point that noon - traditionally one of the most expensive periods of the day - is now one of the cheapest periods to buy and sell power. The system clearly works, but there is backlash developing as the fossil fuel companies realize that solar power is changing their profitable status quo.

angryrobots posted:From "our" standpoint, the current model of distributed solar is both unsustainable, and is being subsidized by our members who cannot afford solar. (And in many cases, the installation costs of individuals will take many years if they ever pay off. So the real beneficiary here is a private contractor who charges exorbitant installation fees to put in the PV array, with a big sales pitch and promises). I think the concern here (and it mirrors similar debates in other parts of the green economy sector) is that the desire to ensure everyone pays their "fair share" is going to result in a huge over-correction that discourages anyone from investing in green technologies because there's no personal benefit. And that the public loses out on the opportunities offered by these consumption reductions and increased efficiency. That is certainly occurring with these solar rate changes, where Republican legislators are intent on eliminating any possible benefit for solar adopters, in the hopes that oil and gas plants will remain the default solution. You see this in the "road tax" proposals that would have electric cars heavily subsidizing fuel hogs and semi-trucks, or water usage tiers that make high consumption easily affordable without offering any reward for conservation. It's this bizarre inversion of the free market, with Republicans defending the role of centralized private/public monopolies and promoting the concept of price fixing. Surely any reasonable system must be able to discourage waste, and encourage diversified investment into that market when it would improve the system as a whole. As a corollary: Each year the EnergyStar program saves Americans upwards of $15 billion in energy costs. It has created a massive industry in appliance upgrades and recycling. In many ways it has had more of an impact on the energy sector than all the rooftop solar projects combined. But all that rides on the microeconomics of personal benefit; if the money that those consumers save was systematically redistributed to subsidize the non-adopters and the electric utility profits, then they would never make those investments. And the nation as a whole would be so much the worse for it. The clear mandate here is to ensure that these sorts of programs can be viable going forward, and that consumers have a reason to invest in green technologies that benefit their communities as a whole.

And all those natural gas plants are still dumping exhaust.

While renewable energy generation is here to stay, it isn’t the magic bullet that solves all the energy needs of the US on its own. The one thing I don’t see getting discussed often is the need for reactive power resources (both capacitive and inductive), and sources of inertia for the system to ride through transient events like faults. There are devices out there that will help with this issue. SVC (static Var compensator) are a good resource that can add or subtract Vars from the grid in a matter of cycles. But a transmission voltage SVC costs somewhere in the neighborhood of $30 million installed for 600 MVar. That’s going to be a little expensive for utilities to swallow.

This project was never about adding jobs to NH or reducing our energy prices. It was about destroying one of our more important resources that continuously brings a huge amount of money to poorer areas of the state in order to sell power to southern New England. If Eversource would have been serious about his benefiting NH they would have guaranteed lower rates to ratepayers and reduced carbon emissions from their portfolio as part of the deal but of course they would never do that.

On the one hand, I grew up in Oregon's Willamette Valley which had all sorts of power lines running through the forests down from the dams and wind farms on the Columbia and the Willamette, and they really aren't a big deal. It's a price to be paid for having clean energy, and it's a fairly minor one. On the other hand, it's good that the regulators are paying attention to the desire of the citizenry, rather than just ignoring the people who will primarily affected. So one part "grumble grumble idiot NIMBYs" and one part "nice work with the responsive small government".

I might be missing something, but what is the complaint about this line? They are putting underground cable through the National Forest section. Yes, for a year there will be some destruction of the forest as they install the underground conduit for the cable. But after that, no towers to obstruct the view, and after some number of years, the trees will have grown back.
