and we are still debating about Net Metering..

In my view, this is simply hoax being created by Utility Companies in advance to protect slide in their business in long term. Solar panel based electricity production is dampening their growth in short term and in long term going to kill them.. They are starting all this noise so these net metering could be killed and solar panels become un-attractive for future home owners. They know for sure that solar panel prices are continue to fall and within 5-10-20 years, they will become norm at each house.

Here is my take on why net metering is valid and in fact not only eligible for retail rate but in my view even higher prices then retail. Here are some of thoughts on this:


  •  Solar Panels usually produce maximum when we have peak demand and help reduce peak demand of the grid. Utilities maintain specific peakers (small power plant or additional capacity in power plants) which they can get rid of or at least reduce capacity
  • Regarding this talk about retail Vs wholesale price paid for electricity pumped back to grid by homeowners - this electricity is produced right next to the consumption point.. theoretically, your next door neighbor might be consuming the additional electricity generated by solar panels. It is not that this power is bloody going back to power station traversing all the transformers and grid.. NO.. It just uses few meters of the power cables and it gets consumed right next door.. It actually takes out the stress of grid and in a way help elongate life of the equipment. Reducing their failures and thus reducing their maintenance costs.. In a way it reduces overall transmission and distribution losses incurred while transporting electricity from central power plants to your home. In my view, they should be paid more than retail price!! and this is no joke..  even utility companies knows the value of this distributed generation.. 
There can be hundreds of more logical reasons be listed in favor of these solar panels.. there is no end to this discussion.. Ultimately , they are good for consumers and they are good for  environment.. It is definitely not good for utilities in long run.. However, utilities need to decide, whether they want to die gracefully or they want to die in anguish and pain.. moreover, they are not going to die completely any how.. at least in 30-50 years for sure.. there role could become infrastructure service provider instead of providing electricity itself..


‘NET METERING’

Analysis says solar will carry high cost


Industry battles news that nonusers may pay $1.1B per year by 2020


By Dana Hull


 


A long-awaited analysis of “net metering,” the policy that allows homeowners, school districts and businesses to offset the cost of their electric use with the rooftop solar power they generate and export to the grid, finds the policy will cost California’s nonsolar customers $1.1 billion a year by 2020.

The lengthy “California Net Energy Metering Evaluation,” released Thursday by the California
 Public Utilities Commission, will strongly influence discussions among state regulators about how to restructure electric rates.
The solar industry is already crying foul, saying the study design was stacked against solar. Others say it’s time for net metering to be overhauled.

“There’s no question that there’s a subsidy to solar customers,” said Marcel Hawiger of TURN, the Utility Reform Network. “Net metering was a policy designed to jump-start the solar industry in California, but it’s not a sustainable policy.”

Large utilities like PG&E have a four-tiered rate system: The more electricity you use, the more you pay. Tier 1 customers pay 13.2 cents a kilowatt hour for electricity, while at Tier 4 it’s 35.1 cents. The tiered rate structure has been a big driver of rooftop solar in California, since many homeowners who go solar do so to cut down on high monthly 
bills. Solar customers are reimbursed for the electricity they generate and export to the grid at the retail rate.

Utilities have argued that under the current rate structure, customers using net metering do not pay their fair share of the costs of the transmission and distribution grid. And since solar customers tend to be more affluent,
 utilities argue that lower-income, nonsolar ratepayers are subsidizing solar customers.

The solar industry is already fighting back against the report, noting solar is increasingly being adopted by middle-income consumers, creates jobs for installers and that everyone benefits from “avoided costs,” or the need for utilities to build additional power plants.

“The study design was stacked against solar,” said Susannah Churchill, solar policy director at Vote Solar, a solar advocacy
 group in San Francisco. “To do a cost-benefit analysis and not include benefits like public health and jobs just inflates utility claims. Rooftop solar is a threat to the utility business model, and they are doing everything possible to stop its momentum.”

The report, by the San Francisco- based consulting group E3, found that most homeowners who have solar systems are high energy users with an average household income of $91,000, well above the state average of $54,000, and that the savings
 that solar customers achieve on their own bills is shifted to other ratepayers who must make up the difference.

PG&E has more than 93,000 customers on net metering and adds roughly 2,000 more each month at a pace that, from a utility perspective, is not financially sustainable.

“PG&E has long supported solar for its environmental benefits,” said spokeswoman Lynsey Paulo. “We are the largest buyer of solar energy in the nation, and lead the nation in the number of customers
 who have installed solar on their rooftops. We look forward to working with lawmakers, regulators, industry and our customers to chart a path to a bright and sustainable solar future.”

E3 will present the results of the NEM study in the PUC auditorium at 505 Van Ness Ave., San Francisco, on Friday, and is accepting public comments until
 Oct. 10.

Infrastructure of India Inc.

It really saddens me with the news like this from India. It is still amazing.. Such a great nation with such a great progress in recent decades and here we are.. as if living in stone age. Come on.. enough is enough.. we have to fix this infrastructure issue. In particular, power, water, sanitation and road. Roads have improved a lot.. but Power and Water is still big time issue. There is no excuse of some states doing better and some states worse.. The state from which I come from.. UP (Uttar Pradesh) is one of most populous state of India I think even after splitting it. Power situation is so bad.. for whatever reasons.. though mostly political, corruption and total mis-management.. Despite the fact that this state has lot more power generation capacity.. but this state's utilities (mostly Government Organization) simply doesn't have capability to buy power from these Power Producers as they simply can't recover money from customers. It is that simple to the core of it..

Despite significant progress in so many areas of IT/Shopping/Cars/Transportation/etc.. basic infrastructure is still missing.. Why can't government simply fix it.. One simple reason I can think off is these so called social programs.. I don't know if we still have those so called "Garebi Hatao" programs... they didn't remove any poverty.. they simply made politicians and bureaucrats stinking rich.. I think, now the campaign from middle class should be to educate and make these poor people aware of simple facts that there is no free money and these kind of programs are not going to benefit them. They will simply keep them poor.. Instead of this, government should channel all the money into infrastructure like power, water, roads.. and leave rest of the areas to private sector.. This will automatically fix problems and hopefully progress will percolate to these poor people.. Or even, let these infrastructure projects should be taken care by private sector.. simply put, public sector can only breed corruption..

Another very important change which India needs is in their bureaucratic system.. They simply need to abolish this Civil Services organization.. It was designed to serve Britishers to rule easily.. its purpose was served when we got independence.. It should have been abolished at that time.. but better late than never.. I know.. it is easier to write and scream about it.. but difficult to change.. However, I am sure with power of internet, it can be done.. I am hopeful that it will be done sooner or later.. without that, India will remain in shackles of these politicians and Civil Servants.. There has to be accountability at each level.. Why we need District Magistrate, who is coming from outside to manage district's (or County's) affairs.. Why can't we have District/County supervisors who are elected by the people.. once there are multiple democratically elected positions, it should hopefully make politics as career of choice for many more young people. Obviously, we need restrictions on number of terms any particular position can be held by any individual..

I think I digressed from my main topic of Infrastructure to political systems.. But in reality they are both very closely linked.. it will be difficult to have any real progress without fixing both of them..


Power supply restored in 70 % parts of north India

New Delhi, July 31, 2012, (PTI) :

Electricity supply has been restored in close to three-fourth of the areas in the northern region, including the national capital, that were severely impacted by power outages since today afternoon.

A handwritten notice about power failure is pasted outside a Metro station after Delhi Metro rail services were disrupted following power outage in New Delhi, India, Tuesday, July 31, 2012. India's energy crisis cascaded over half the country Tuesday when three of its regional grids collapsed, leaving more than 600 million people without government-supplied electricity in one of the world's biggest-ever blackouts.(AP Photo/ Manish Swarup)Seventy per cent or 24,300 MW of power has been restored in the northern region, including Delhi, till 1930 hours, Power Grid said in a statement.

In Delhi, 100 per cent or 4,100 MW, has resumed.

State-run Power Grid, which manages grids across the country, said that "supply to (Delhi) Metro and Railway traction (was) restored at 1530 hours".

Power Grid said full electricity supply has been restored in the North East.

In the Eastern region, 50 per cent supply has been restored till 2030 hours.

Triggering a major power crisis, the three major grids -- Northern, Eastern and North Eastern -- failed at 1300 hours.

Even though the exact reason is yet to be ascertained, officials said that problems started in the Eastern Grid and there could also have been over drawals by some states.

Great year for Solar Energy!!

Again, market economy at its best. Solar capacity installed is doubled while solar panel prices are halved. New installations reached close to 2000 MW in US in 2011. Even though they don't produce electricity 24X7 still energy produced by solar panels is most precious as it comes and supports peak hour load in US which is typically afternoon hours of Summer. Theoretically, this should lead to direct cut in reserve capacity requirements of utilities thus making electricity cheaper for everyone.

Great news and I hope that this trend will continue globally. At the same time, I think very soon it will result in another headache for utilities. Utility's main job will be just to transmit and re-distribute electricity. They will be tasked only to provide emergency and base load. This issue has already started surfacing in requests from utility to charge for solar connectivity charges for homes and businesses who have almost zero electricity bill due to offset from electricity pumped back to grid. As of now, it is simply helping utilities by limiting load growth on their existing setup. However, sooner or later it does need to come into force so that they can start charging connectivity charges if net consumption by customers is less than certain threshold.

On other hand, there is another monster electricity consumer is there at the corner. "All Electric Cars"!! It is already picking up and sooner or later on it will become big enough requiring special attention to its requirements. Assuming people will use electric cars for daily office commute, they will need to charge their cars hopefully during pre-noon to noon time period. Then, they will be needing it late evening/night time to charge back once they are back home. Both the places will need this infrastructure and additional capacities. I hope that it will use off-peak load capacity and will help utilities further smoothen their demand curve thereby making better capacity utilization and provide cheaper electricity.

Here are the details from Mercury News:

2011 record year for solar installations

Industry execs say market share will hit 15% by 2016


By Dana Hull


 


The amount of photovoltaic solar panels installed in the United States more than doubled from 2010 to 2011, representing a historic year for the American solar
 industry. A year-in-review report jointly released Wednesday by the Solar Energy Industries Association and GTM Research found that 1,855 megawatts were installed nationwide in 2011, up from 887 megawatts in 2010 — for a growth of 109 percent. “After a record-breaking 2011, the U.S. has proved itself as a viable market for solar on a global scale,” says the executive summary of the report. “In 2011, the U.S. market’s share of global (photovoltaic) installations rose from 5 percent to 7 percent and should continue to grow. We forecast U.S. market share to increase steadily over the next five years, ultimately reaching nearly 15 percent in 2016.” Installation figures for photovoltaic, or PV, solar panels, which convert sunlight directly into electricity, include those on homes and businesses as well as much larger, utility-scale power plants.One megawatt is enough to power about 750 to 1,000 homes. But because the sun doesn’t shine all the time, solar industry experts typically say that 1 megawatt of solar power capacity is sufficient to power about 200 households. California continued to lead the nation, installing 542 megawatts, accounting for 29 percent of all installations in the country. Next came New Jersey, Arizona and New Mexico. More than 61,000 individual solar projects were completed in 2011, including many large installations serving commercial or utility scale clients.

There were 28 projects larger than 10 megawatts each, up from just two in
 2009. “We’re seeing an incredible increase in the number of utility-scale projects,” said Rhone Resch, president and CEO of SEIA. “There’s technology acceptance of solar by utilities and companies that traditionally built natural gas power plants. Solar is the next great opportunity.”

The record number of
 installations was fueled, in part, by a free-fall in solar panel prices, which dropped more than 50 percent in 2011.

But lower prices put enormous pressure on solar manufacturers like Fremont-based Solyndra, which filed for bankruptcy in September.

Solar still counts for less than 1 percent of California’s electricity, most of which comes from natural gas, two nuclear power plants and hydropower.

But advocates, including Gov. Jerry Brown, want solar to play a key role in the state’s energy future, in part because solar projects generate local installation jobs. Brown hopes to add 12,000 megawatts of rooftop solar generation by 2020.

California utilities are also under pressure to meet the state’s aggressive Renewable Portfolio Standard, which calls for 33 percent of electricity to come from renewable sources by 2020. In 2011, San Franciscobased PG&E began receiving power from five solar photovoltaic projects built by independent developers, bring 135 megawatts of new capacity online.
