NREL Releases Updated Baseline of Cost and Performance Data for Electricity Generation Technologies 2016

Every year the cost of power generation projects are changing in function of technological changes, changes in prices of supplies or due to economies of scale.
NREL has recently publish the  2016 version of the Baseline of Cost and Performance of  most technologies used nowadays for power generation showing the flat trend of prices for conventional energy and the impressive decline in prices that have renewable energies, especially Solar PV with Capital Costs of up to 0.9 [MM USD / MW] for PV at utility scale.
I’m excited to think that the day has come when renewable energy is economically competitive with traditional energies and has reached the point where they no longer need subsidies to displace old and polluting forms of energy production.

Clearly the future is greener…

Tambo Real Project

In the last time (years) I’ve gone from been a solar researcher to consultant and then to Project Manager of solar projects. I have had very little time to write on this blog and to advance in my project to develop a program for the analysis of radiation data files.
Many times the work and personal life does not leave time for much more, and hobbies should be postponed.
As Project Manager I was responsible in juwi for the development of Tambo Real project, which has a capacity of 1.2 MWp and is located in the Vicuña, Chile.
It was a great experience to be in charge of the construction of the second largest photovoltaic park in the country so far, of which I remain many lessons learned.

I would like to share with you some pictures of the construction process.

Day of work at the laboratory

This video is quite old, is the result of a time lapse of a day working with a friend in the solar laboratory of UTFSM trying to build a shader on the tracker for a pyranometer. The shader consisted in an arm as a inverted L with a disk that blocks the direct rays of the Sun, this arm was lifted by the arm of the tracker that supports the pyrheliometer.

Here you can see where is located. (Google Maps)

And here is the final result…


In my last year of college I started working in solar energy research, processing large amounts of data of global, diffuse and direct solar radiation. The processing of this information was very difficult, considering that a year of measurements means more than 500,000 data measured every minute. For each data had to calculate the position of the sun and do quality control of measurements, it was impossible to do it in Excel due to long processing times and freezes. It was then that I began to process information with Fortran, everything was much faster, did not fall and was able to process lots of information quickly. The problem was that was not possible to generate graphics and that was critical for me.

This is how I reach DISLIN, a library to generate incredible graphics from Fortran, very easy to use and export to all formats. With the time I even use Dislin to generate Graphics Users Interface (GUI) for Fortran software.

Below are images with more than 200,000 points that was realized in a couple of seconds with Fortran and DISLIN.

NREL Solar Prospector

The National Renewable Energy Laboratory of United States (NREL) has done an amazing job developing the Solar Prospector, a tool to navigate through data derived from satellite imagery with a resolution of 10×10 km. This mapping tool is designed to help developers site large-scale solar plants by providing easy access to solar resource datasets and other data relevant to utility-scale solar power projects.

Unfortunately the information is only for United States.
