Tigercomm’s Mark Sokolove to Speak at CSP Today Conference on “Communicating the Value of CSP to the Public”

2 min. read

Last week, we interviewed Belen Gallego, Founder & Director at CSP Today and PV Insider, in conjunction with the CSP Today 6th Concentrated Solar Thermal Power USA Conference she’s putting on in Las Vegas this Wednesday and Thursday (June 27-28). In addition, yesterday we published our interview with Frank “Tex” Wilkins, Executive Director of the Concentrating Solar Power Alliance (CSPA). This Wednesday, Wilkins will be speaking on a panel moderated by Fred Morse of Abengoa Solar, and including Tigercomm Vice President Mark Sokolove.

Interview: CSP Today Founder Belen Gallego on the Future of Concentrated Solar Power

6 min. read

The following interview is with Belen Gallego, Founder & Director at CSP Today and PV Insider.  Ms. Gallego is also in charge of CSP Today's range of conferences and trade shows, including the upcoming CSP Today 6th Concentrated Solar Thermal Power USA Conference, being held in Las Vegas beginning on June 27-28.  For a helpful discussion of CSP, see the National Renewable Energy Laboratory's page on this topic. Also, thanks very much to Belen Gallego for taking time out of preparing for the upcoming conference to provide thorough, detailed responses to our questions!

Scaling Green Question #1: What do you see as the main opportunities and challenges – economic, political, technological, etc. - facing solar power generally, and Concentrated Solar Power (CSP) specifically, in the United States?

Belen Gallego: In order for the CSP industry to further develop, we need to look at resolving a few challenges for sure. Economic challenges aren't a rare occurrence at the moment, unfortunately. In fact, they affect most industries, as they are to a very large extent due to the world financial and economic situation. CSP is a proven, bankable technology, and in normal circumstances  it would be possible to finance even large-scale projects.

The biggest technological challenge that we have right now is reducing costs. This is already well under way, as costs have dropped significantly over the past 6 years of plants in operation, although more remains to be done. We need to remember that the rate of cost reduction in CSP is very respectable compared to many other industries. If I remember correctly, 6 years ago we were talking about $4.50 per installed watt for PV and now we are at less than $1.00 per installed watt.  This leapfrog type of development does happen, but it needs time and critical mass. Keep in mind that the PV industry had a history of 20+ years before CSP!

The political challenge, which is also a NIMBY challenge, that we face is communication. Renewable energy appeals to the end consumer, as well as to governments, and that appeal makes sense, because to avoid climate change and an uncertain energy outlook, we must develop the right technologies. However, as a niche industry, I believe that CSP isn't doing all we can to communicate the immense value that CSP has for grid stability, for example. It is by communicating the inherent value added of CSP that the technology's full potential  and key role to play will be understood.

In the end, I feel that often the greatest challenge is to be patient. Infrastructure projects of this size and complexity take years to come to completion, and for the market to gain gravitas takes much longer. We have come a long way already, and sometimes we forget that the time scales involved makes it difficult as a speculative market. CSP development may be slower, but it is organic and sustainable.  You just can't compare the CSP industry with the dotcom boom; it doesn’t work like that.

Scaling Green Question #2: According to a recent article at CSP Today, “Growth in the Concentrated Solar Power (CSP) sector faltered last year as photovoltaic (PV) module prices dropped,” but in the long run “CSP’s ability to incorporate thermal storage and to supplement conventional power generation offers benefits beyond the value of the kilowatt-hours they generate.” How do you see this situation evolving in coming years, and specifically do you believe that CSP will gain on PV in terms of cost competitiveness in the near term?

Belen Gallego: When people ask me this question, I like to compare the Spanish and U.S. markets  because I feel that the Spain is a small case study of what will happen in a bigger market like the United States. In Spain, we have a very well-managed national grid, which is relatively modern.  We built in 2008-2009 over 4GW of PV, as well as over 21GW of wind capacity as of 2012. The renewable energy electricity production share hovers around 20%. However, what is not widely known is that at certain times of the year, sometimes in the right conditions the share of energy produced from renewables can reach as high as 50%. That amount of peak power is difficult for the grid to integrate, to the extent that plants sometimes need to be disconnected, meaning that the energy is lost because the grid can´t absorb it. It is only a matter of time until the United States has this kind of peak power integration problem, and CSP with storage can really help manage this issue.
