All Answers: Re: [pakgrid] Reverse Metering + Solar Panels

Someone just told me that in some parts of India, they have installed circuit breakers that trip when the load in a locality goes above a certain limit determined on the basis of the number of families living there. As a result, where there is excessive theft or where people try to run unapproved commercial/industrial centers, the system trips, making such theft etc impossible. I have googled but did not find anything on this. Does anyone knowif this is true or if something along these lines is viable?

If so, this could be part of the solution in Pakistan as well. At a time of emergency, there should also be limits on how much load households should be allowed to use. We do tend to use a lot more air conditioning and lighting than we need to. Sometimes one enters an office and after a few minutes, one starts shivering. It's is absolutely crazy. Better ventilation and design of houses and offices can also significantly reduce the need for air conditioning.

Another solution could be to change office timings in summer. Since sun rise in summer is between 4-5 am, office hours should be something like 6 am to 2 pm. In the earlier part of the day, the temperature is better and that could allow people to work in their offices without too much air conditioning. The late afternoon/early evening would then be available for people to go out for shopping etc, and this might make the traders more willing to close their shops before sunset without being worried about the loss of business.

All this may sound too drastic but extraordinary crises call for extraordinary measures.

The solar panel system can be more useful, if we use 'Reverse Metering' system:

Govt. may help people buying solar panels on soft loans.
Govt. may recommend/approve solar system specifications to be used.
Distribution Companies can launch 'Reverse Metering' system. Excess energy, in the day, at end user premises may be accepted by respective grid. When end user gets advantage of energy units this will make the project feasible. End user will try to install more and more solar panel at its premises and end user will try to maintain it in a good state to get advantage of free energy.
Generation Companies may generate more energy in the night and less in the day. Because more solar energy is available in the day.
End user will not need a big battery bank for storage for night use.

Is this workable? What are your comments?

·         I wish that Reverse Metering idea move forward and red tapes removed.

Habib Rehman <habib@buraq.com>

·         System already in place in Australia.

·         It is workable solution that solves energy crisis in days.

Naveed Arshad <naveedarshad@gmail.com>

·         System already implemented in many countries.

·         Problem is not the technology but the willingness of the Government.

·         Best part is the environmental friendliness.

·         Nowhere in energy policy we see environmental friendliness as a criteria for measuring a technology.

Mubbashir <mubbashir_2004@yahoo.com>

·         The proposal is implementable giving way to a free market where everyone can PRODUCE electricity.

Waqqas Akhtar <waqqas_akhtar@yahoo.com>

·      EU have enacted "feed-in tariff" laws that require electric utility companies to make payments to solar-power producers, be they commercial power plants or private homes

·      Such tariffs have turned Germany, France and Spain into solar power leaders.

·       To encourage people to buy and install solar panels, Germany buys solar-produced energy at a fixed price guaranteed to make a profit.

·         Even Govt. takes initiative on first two points it can make a huge difference.

·         Reverse Metering can add lot of administrative and operational hassles. Although it is doable but not in the current scenario.

·         'Grid-Tied Electrical System' is used in many countries:

·         No battery banks are required for Grid-Tied systems, this system really pays back.

·         But, Grid-Tied or Grid-Interactive systems don't work in the case of power outage.

·         Pakistan needs to take the quality of its grid into account when planning distributed generation (and reverse metering).

Mohammad Asad <asad@buraq.com> from Buraq Integrated Solutions

·         Pakistan Engineering Council (PEC) has already implemented On-Grid Solar Power System. http://www.pec.org.pk/JICA_projBrief.aspx

·         The new energy meters which are currently being installed are supporting Reverse-Metering.

·         I think it is a great idea. But instead of Govt. motivate public.

·         End up not having to deal with wapda at all.
