Buy this paper for a Christmas/Chanukah present for your upper level/graduate student who is studying Climate Change

I presented my peer reviewed paper, A Financial Algorithm for Computing the Levelized Cost of Storing PV Electricity (LCOS), at the poster session of Solar Power International 2017 (SPI-17), Monday, 11 September, 5pm-6pm, Las Vegas.  I enjoyed talking to those of you who stopped by my poster! Comments that SPI-17 attendees made to me have helped me to improve my SPI-17 paper. As a result, my improved SPI-17 paper (Version 2.00) is now available below. Thank you! 

I am not new to the technology and finances of energy storage!  I have 14 years of experience. My first energy storage paper was, A Financial Worksheet for Computing the Levelized Cost of Wind Electricity (US$/MWh; €/MWh) Stored in  a Hydrogen Energy Storage System, WindPower 2003, 18-21 May, Austin. TX. I presented a European version of my paper at the International Solar Energy Society's Solar World 2003, 14-19 June, Göteborg, Sweden (The European version was not that hard to write as the rules of physics and chemistry are the same in Europe as they are in the US).

What goes on in Vegas stays in Vegas except that I hope that my SPI-17 Energy Storage Paper does not stay in Vegas. You can buy my paper even if you do not keep it in Vegas!

Below the paper Abstract are instructions on how to buy my now much improved paper (Version 2.00) and its two Excel worksheets (Version 2.00). You will also receive a copy of my SPI-17 Poster (Version 11) suitable for your home or office or for your (grand) children's bedroom wall.

For more information on my poster presentation at SPI-17 go to:    


This paper discusses the financial and technical principles underlying the levelized cost method of computing the cost of storing solar (PV) electricity (LCOS). The paper presents a levelized cost (LC) algorithm. The algorithm uses nine recognized energy storage system (EES) specifications to compute the levelized cost of the stored electricity. The algorithm equations are presented. Published ESS specifications are cited. For rapid computation, a worksheet is provided. The goal of this paper is to present a standard computational algorithm for financial analysts to use. A financial analyst can do a levelized cost computation based on paper’s LC algorithm and on the algorithm’s nine ESS specifications. The paper’s algorithm gives the analyst who has an ESS specifications, a quick “back of the envelope” verification of a developer’s (utility-scale), manufacturer’s (C & I; residential), or researcher’s (prototype) value for the cost (US$/MWh; €/MWh) of energy storage. This paper also has a case study that demonstrates how to obtain/develop the nine ESS specs. Published specs for the Eos Aurora® (a utility-scale [1 MW 4 MWh] DC battery ESS manufactured by Eos Energy Storage)  and Cabin Creek (a utility-scale [300 MW 1,450 MWh] Pumped Hydro ESS in Clear Creek County, CO owned by Xcel Energy) are used in the case study. Because the ESS CapEx is a required spec, the LC algorithm can also be the basis for an ESS financial (forensic) valuation. A second paper will compute the LC of using an ESS to provide ancillary services (frequency and voltage stabilization  plus VARS). A Poster handout was provided. The paper has now been revised (Version 2.00) to take into account the suggestions of the SPI-17 attendees.


ONE,  you should know that if you wanted to buy my paper, A Worksheet for Computing the Cost (US¢/kWh) of Solar Electricity Generated at Grid Connected Photovoltaic Plant, Journal of Solar Energy Engineering Paper (JSEE), August, 2002, Vol. 124, Issue 3, page 319, from the JSEE website, the JSEE will charge you US$25 for the pdf file and there is no Excel worksheet (xlsx) included.   

TWO, you should know that my Vol. 124 article was one of the top ten articles downloaded from the JSEE website in the following months; November, 2006; December, 2007; February, 2008, October, 2008. 

THREE, you should know that if you wanted to download my paper, The Carbon Content of Hydrogen Vehicle Fuel Produced by Hydrogen Electrolysis, JSEE, February, 2005, Vol. 127, Issue 1, page 161, the JSEE will also charge you US$25 to buy the pdf file and again there is no Excel worksheet (xlsx) included.   

Confirm my first three talking points by doing an author search @ 

FOUR,  you should know that I got invited to the SPI-17 SEPA Group Lunch. It was nice to receive the invitation, but then I had to pay US$25 for the Lunch. Why did I bring this up? Everybody knows that there are no free lunches (per Lenard Cohen who heard it from Milton Friedman who was told by a Chicago bartender that the lunch at the bar was free but that the drinks were not). I am just reminding you that there are also no free papers (pdf), posters (pdf) or Excel worksheets (xlsx). 

FIVE, students, If you asked for a free copy of my paper, poster and worksheet(s) because you are a student, you should know this!  You have to pay tuition to go to college. You have to pay for your textbooks.  Why should you not pay for my paper? Just think of my paper as a supplemental reading that your professor assigned you to read.  Don't forget students!  You also get a copy of full color copy my poster for your dorm wall.

SIX, I am now offering a holiday bonus. If you buy my comparative LCOS worksheet (US$10), you will now get, at no additional cost, a second worksheet, Table III,  Inflation Adjustment Excel Worksheet, to compute the current inflation adjusted price of an historical price. The historical price can be adjusted for monetary inflation and for increases in productivity.  For example in 2002, when my Vol. 124 paper was published, its pdf was sold by the JSEE for US$25. When I use the Table III, Inflation Adjustment Excel Worksheet to adjust this price to 2017 (15 years) and use a 2%/year inflation rate (which is the Federal Reserve's current [11/2017] target for yearly monetary inflation as a substitute for the PPI) my Vol. 124 JSEE paper should now sell for US$33.65 (€29.49). The JSEE still sells my Vol. 124 paper for US$25 (€21.91). One explanation  for this constant price is that the increase in the JSEE paper ordering process productivity (MPP) has also been 2%/year for the period 2002 to 2017. This means that an increase in a price caused by inflation is just offset by reduction in the price caused by an increase in productivity. 

SEVEN, you should know who you are buying from. Download my 19 May 2017 Short Form CV (resume) at 

EIGHT, To help celebrate the 2017 Chicago Climate Charter, I am giving a Chicago Climate Charter Bonus for those of you who have bought my SPI-17 paper.  You can now buy a one hour consultation (a one hour Q & A session on my SPI-17 paper) for only US$125/hr. This is half the going rate.  Email me at to set up an appointment! 

NINE, don't forget that my family name, STAVY, on this website is in capital letters because French was the host language at the 2015 Paris Climate Change Accord. In French, the family name is CAPITALIZED.  This is my story and I am sticking to it.

My SPI-17 Paper, A Financial Algorithm for Computing the Levelized Cost of Storing PV Electricity (LCOSE), costs US$25, the same price as my JSEE papers.  You get a pdf file of my paper, a copy of my SPI-17 Poster (pdf) suitable for home or office and working copy of my paper's Table I Excel LCOS Algorithm Worksheet (xlsx).

My SPI-17 Paper's Comparison Case (Paper Section IX) Excel LCOS Algorithm Worksheet (xlsx) now with the Table III,  Inflation Adjustment Excel Worksheet, with cost you an additional US$10 which is less than the price of my SPI-17 SEPA Lunch. 

I accept orders and payment through both POPmoney and through PayPal. US$35 for my paper, the poster and both Excel LCOS worksheets; US$25 for my paper, the poster and the Table I Excel LCOS worksheet; or US$10 for only the Comparison Excel LCOS worksheet) now with the Table III,  Inflation Adjustment Excel Worksheet.
