Renewables: Optimising & Right-sizing II

Posted by Jalal Aslam | Posted in Uncategorized | Posted on 07-02-2010

Salam & Hello!

I hope you are fine! wherever you are.

This is my first blog, of the new year 2010.
The new year has dawned with renewed sense of doing something about our energy crisis,saving energy, as we have witnessed resumption of electricity & gas load-shedding.

Once again our Energy reservoirs have come under spotlight. We have also witnessed criticism of government over the issue, over the load shedding & over the rental power projects. We need to think & act at our own level, both industry-wise & both at our city/town,province level, first. If we wait for our government to act first, we may miss the train.

Well! continuing from where we left the last time:

Depending upon the load-size, the time of backup (usually multiple of days) & the depth of the pocket of the investor, the Renewable portion can increase or decrease to find a best-effort value in a Hybrid-RE system. In Hybrid-RE system we use a Petrol/Diesel Generator,in addition to PV & Wind-generators. off course the solution as discussed earlier has to take into account the initial survey(s) and the met. office data. for a particular location.

The first thing is to know your equipment load accurately.
The battery backup size or broadly speaking the backup time depends upon
your requirements i.e. design requirements .

The challenge is for the designer & investor to agree on a “best-effort” or optimised-value. This is the most important part & the most difficult part. The others are: know thy weather,location accurately,calculate & estimate the logistics accurately and the last part is the deployment phase.

I hope you have enjoyed it so far….

In the next blog, I shall try to build on the “best-effort” value and important things to consider.

Until then have nice time & fun at your job or whatever you are doing
