clean energy
With the rise in the cost of electricity it has become important to swich to an alternate source like solar energy. There are even solar funds available. For more information get quote at clean energy corp.

Re: Loosing Business is bigger threat
I also totally agree with you. In developing countries like ours, government has a major role to play in such projects. Solar Power business here also is there in the market for a long period of time,but the question remains how many from the market has really taken the use of it? Unless otherwise government push these projects forward and make some policies over it, these will remain stagnant in the market for another longer period of time.

Only half the solution
Interesting, we have a similar situation here in Australia, but probably not to the same extent.

PV power is a good idea, but it is only half of the solution. many people get into PV as their contribution to "being green". Unfortunately, the way PV is sold is back to front. Buildings (predominantly residences) with PV contribute to some extent to the daily business peak, and for their efforts get back some "revenue" form the utility companies.

Unfortunately, when they get home from work, they need to start consuming more power from the grid, which is most likely sourced from fossil fuels or gas - which is not so green.

A better solution is to make a residence (not practical with businesses, though offsets some of their costs) self reliant. This means going off grid - putting in a bank of batteries that can charge in the day and supply power at night is the better solution - And a FULL one as well!

Going Off-Grid seems to be a greener approach, to me, but governments don't want to know!

Just saying...

Re: Any information regarding the smart grid
"If possible can you elaborate on this please  ?"

@chirshadblog: What should I elaborate?

I think I asked a couple of questions.  Is anything confusing or you find any contradicting statements?

Re: PV energy in Grid
"true. It will help us address the issue of power deficiency. But it also poses challenge because it distrupts the balance between supply and demand. We need to develop smart grid to overcome this."

Yalanand, smart grid is one of the solutions for balance distribution. But my opinion is energy generation/conversion has to be increased. Otherwise we may not be able to meet the demands; especially during peak hours.

Re: Grid stability red herring?
The instability problem is significant enough in some states that there have been interconnect agreements denied for new PV installations. One of the real problems contributing to instability is that under current regulations in North America, PV systems only supply Watts, not VARs. PV power factor is mandated to be unity under IEEE1547, and UL1741. All of the VARs come from the utility, and as the amount of energy from solar increase, the VAR load on the utility actually increases as well, and their distribution equipment experiences overcurrent events as a result. SmartGrid inverters can supply VARs, and coupled with energy storage, can provide voltage support as well. Both of those tend to improve the stability of the grid, as it takes the full burden of reactive power off the utility and places it closer to the point of use.

The distributed model (over a city for instance) would tend to be more probabalistic - except for the fact that the local weather patterns tend to affect a large number of sites all at once, so the voltage fluctuations from a sudden loss of aggregate PV feed-in-current still can have destabilizing effects.

Distributed Sources = Higher Marginal Cost
Countries at the forefront of distributed solar-electric implementation are discovering a downside.  As customers draw fewer KWHours off the grid, the marginal cost for the remainder goes up.  Who pays this higher cost?  Perhaps the answer is for everyone to install solar systems and share equally; but, so far the bureaucrats answer has been to put a surcharge on the solar users.  ...a complete 180 turn from subsidy to penalty - or even crazier, national level subsidy AND local penalty.

Re: Loosing Business is bigger threat
There is no option of keeping government out of matter. As we need to take permission from Utility company before connecting solar power plant to the main grid which is valid. But they will hardly give permission to anyone. Today we are pushing the rooftop solar pv to the domestic market but there is no one to take it because people are not getting credit for what they feed. And there is no policy implemented by government for this also. But sooner or later we will definitely get the same implementated, and that will boost the market.

Re: Loosing Business is bigger threat
Many incentives were lost for solar in Europe which led to a shakeout of the market and bankruptcy of many within the supply chain. The industry has improved after this market correction and business and stock prices have improved.

smart grid tech
The Recovery Act stimulus program funded nearly a billion or so for a smart grid overhaul. However, the real push for smart grid tech would be the increase of renewables up to about 20% per state contributing to overall power gen. That has not happened to a degree needed to overhaul the grid for this less stable form of power.
