Cost of power outage to Pakistan Economy

Pointing out the obvious problems (that are actually symptoms of underlying issues) is very easy and therefore frequently discussed. Thus, when I read Mr. Burki’s article in opf blog (, it inspired me to praise it as well as expand on a couple of items. And since I didn’t see any reference to socialism, I am basing my analysis on assumption that we are talking about market economy and democratic Pakistan.

Here is my take on what are the real issues and solutions.

Big Sur's Post Ranch Inn (CA, USA) Goes Solar

May 5, 2009

Post Ranch Inn has switched on a panel solar installation, one of the largest hotel solar projects in California. The solar array is owned and operated by Recurrent Energy, a distributed power company and leading provider of onsite solar energy. Post Ranch buys its electricity generated by the system from Recurrent Energy through a power purchase agreement at an estimated lower rate than Post Ranch would pay the utility company. In addition, Post Ranch is now insulated from future utility increases. After 15 years of operation, the hotel can purchase the system at a nominal cost and produce free electricity for itself.

Solar Power vs. A Diesel Generator

Solar Power vs. A Diesel Generator

Today we'll design an off-grid power system. We'll leave out quite a bit of detail so the article will fit in one issue, but we'll include enough to make a valid economic selection between the two approaches. One system will be strictly active solar and the other entirely diesel generator based. Generally a hybrid that includes both solar and a generator will be the most cost effective, but these two extremes are shown here to (1) make some key points, and (2) illustrate the analytical process.
