The document summarizes some of the cost aspects of solar thermal electric (STE) plants in the Middle East and North Africa (MENA) region. It discusses the levelized cost of electricity for different STE technologies and how costs have decreased over time due to improvements in components, performance increases, and reductions in capital expenditures. The document also presents a model that policymakers can use to evaluate the costs and economic benefits of support programs for STE plants.
Course on Regulation and Sustainable Energy in Developing Countries - Session 3Leonardo ENERGY
This session is devoted to the design of feed-in tariff schemes for the large-scale dissemination of on-grid renewable energy technologies in developing countries. More than 50 countries have adopted a feed-in tariff both in developed and developing countries.
Designed carefully, feed-in tariff laws are considered to be one the most cost-effective measure to support renewable energy technologies. In the case of developing countries, there is a need to balance conflicting priorities, especially when it comes to national development objectives such as health, education, employment etc, whereby environmental issues can often be considered as secondary. Therefore the complementary benefits that renewables can bring and the cost of mechanisms to support renewable energy technologies needs to be weighed; renewable energy policies need to be linked to development policies.
After a brief introduction on the motivations to introduce renewable energy policies in developing countries, the session 3 examines the way to design and implement effective feed-in tariff: how to determine the eligible producer and technologies, how to calculated support levels, how to differentiate tariff payment, when to revise tariffs and plan tariff degression, etc.
This is the presentation that i used to talk at the APMG International's launch of Managing Benefits Guidance. This is the new book by Steve Jenner and if you read the back cover you'll see my feelings about it.

3. Cost and revenues issues
The cost of the electricity depends on the DNI, efficiency, CAPEX,
OPEX, financial costs, public supports, expected life, … (LCOE?)
The revenues depends on the dispatch profile and the hourly and
seasonally associated prices along with the electricity price evolution
All projects until now have been promoted on a FiT or PPA basis
Although the “golden end” is a relevant aspect of these plants there
are no commercial ways to take it into account when determining the
financing terms and conditions. It must be explained to Policy Makers
as a big added value when establishing the support programs
Therefore the only practical approach to refer to the cost of STE
electricity will be to determine which is the PPA or FiT that allows
a STE plant to be built.
5. The “harmonization” model for STE costs
“Discount” factors
Plant size
PPA or FiT
duration
Actual PPA for a PPA escalation Harmonized PPA for
given project at a rate a typical project at
certain location
Grants the same location
under specific
without public
support
Concessional support
circumstances
loans
Specific Financial
conditions
Loan duration
DISCLAIMER: This attempt to provide reference prices must be considered approximated. There are many
default values that might be not applicable to all projects as well as some country specific requirements.
6. Cost reduction estimations:
The view from the Industry in 2012
Stars corresponds to “normalized”
PPAs or FiTs in 2012 at their respective
locations in Spain, USA, India, Morocco
South Africa and Israel
Hypothesis: 30 GW
will be built at that time
7. What has been done so far
(Stars mean achievements)
Cost = Cost reduction
Performance increase
Cost reduction:
Structure
Tubes
Mirrors

Cost breakdown for a 50 MW plant with 7 h. storage effort to some extend

investment and financial costs

Performance increase will play
as important role as CAPEX reduction
Both effects together will make
STE plants affordable
