Stuttgart, 28 October 2016

M+W Group and project partners have presented the first results from extensive
research into the benefits of combining the use of solar thermal and
photovoltaic power plants.

The THERMVOLT study, produced by a partnership of M+W Group, the DLR
Institutes for Solar Research and Technical Thermodynamics, the Lappeenranta
University of Technology (Finland), and Fichtner GmbH&Co KG focused on the
efficiency of solar technologies and the security of power supply.

The THERMVOLT Project was an engineering, economic and environmental
comparison of solarthermal (CSP) and photovoltaic (PV) power plants with a
battery storage facility. The research examined how these power plants could
be developed to generate electricity from solar energy that is affordable,
environmentally friendly as well as available around the clock.

The CSP power plants investigated had a thermal energy storage facility
combined with a fossil fuel burner which was used as necessary and linked to
specific emissions limits. The PV combined power plants had a battery storage
facility and a fossil reserve system (for example a gas-fired power plant)
with which they could be operated in a network.

Manfred Engelhard, Technology Manager Energy at M+W Group, explained:"The key
challenge for achieving an increasing proportion of renewably
generated electricity in the grid is related to the availability of effective
and affordable storage solutions. After all, the sun does not shine all the
time and the fluctuation of 'feed-in' therefore rises as the proportion of
solar energy increases in the grid. Electricity storage systems in the form
of large, stationary battery storage banks along with PV systems demonstrate
a high potential for reducing costs. The combination of PV and batteries is
likely to make an important contribution to certainty of supply through the
delivery of predictable electricity at an attractive price."

The results of the study indicate that currently a combination of CSP and PV
is more cost-effective in most scenarios than the use of only one of the two
technologies. The photovoltaic section of the power plant supplies
electricity directly to the grid during the day, while the solar thermal
section stores solar energy in a thermal storage facility. This provides the
capability to feed this energy into the grid as electricity during the night.

On account of the current high level of costs for battery storage, PV-battery
combined power plants are currently subject to the highest electricity
generation costs. However, these costs are likely to approximate to the
electricity generation costs of solar thermal power plants with thermal
storage under favorable conditions by the year 2030, or may even fall below
this level of expenditure.

The initial results of the study were recently presented at the SolarPACES
Conference in Abu Dhabi on 12 October 2016. The final report for the study,
which was financed with a grant of 500,000 Euros from the Federal Ministry
for Economic Affairs and Energy (BMWi), will be submitted by the close of
2016.
