Dear Ms Evans,

Thank you for your emails of 20 February requesting information about
MARKAL.

Your request is being dealt with under the terms of the Freedom of
Information Act 2000.

Your requests were as follows:

1. "I would like to request the source code for the MARKAL
optimisation software."

2. "All input parameters used for the MARKAL optimisation program."

Taking them in order,

1. DECC is licensed to operate the MARKAL model. However we have
been informed that, under the terms of this license, we are not permitted
to pass the source code to third parties. A MARKAL reference manual with
the full mathematical description is available at [1]www.ETSAP.org. In
order to obtain the source code, you would need to apply to the Energy
Technology Systems Analysis Program (ETSAP) to become an operating agent.

2. From our preliminary assessment, it is clear that we will not be
able to answer your request without further clarification.
General information on the input parameters used in MARKAL is available at
[2]www.ETSAP.org. Specific input parameters will apply to individual
scenarios. In order to provide specific input parameters, we need to be
able to identify the relevant scenario. However, you may find useful data
available at
[3]http://www.ukerc.ac.uk/support/tiki-inde...
and at
[4]http://www.decc.gov.uk/media/viewfile.as....
Please note that if I do not receive clarification within three months
your request will be considered to have lapsed (Under section 1(3) of the
Freedom of Information Act (FOIA), a public authority need not comply with
a request unless any further information reasonably required to locate the
information is supplied).

If you have any queries about this request do not hesitate to contact me.
Please remember to quote the reference numbers above in any future
communications.

Yours sincerely,

Julian Hentschel

Dear Ms Evans,

Thank you for your emails of 11, 20 January, 20, 25 February and 1 March
requesting information about MARKAL. It appears you have raised a number
of FOI requests on the same topic. In future, please help us to avoid the
creation of parallel requests on the same topic by ensuring that you the
quote the reference number 10/0361 in all related correspondence. Raising
multiple requests is likely to delay your response and wastes public
resources.

Your requests are being dealt with under the terms of the Freedom of
Information Act 2000.

Taking all of these requests together, you have asked both for the "source
code for the MARKAL optimisation software" and the input parameters used
in each module of the DECC implementation of the MARKAL model.

Regarding the source code, as noted in the response to requests 10/0361
and 10/0362 dated 25 February, DECC cannot provide you with the MARKAL
source code. I have copied an excerpt of this response below:

"DECC is licensed to operate the MARKAL model. However we have been
informed that, under the terms of this license, we are not permitted to
pass the source code to third parties. A MARKAL reference manual with the
full mathematical description is available at [1]www.ETSAP.org. In order
to obtain the source code, you would need to apply to the Energy
Technology Systems Analysis Program (ETSAP) to become an operating agent."

Regarding the inputs, DECC does not normally conduct MARKAL modelling
internally but instead commissions the modelling from third parties. The
latest MARKAL modelling results produced for the Department were conducted
by AEA Technologies. We have asked AEA Technologies about the inputs used
and have been informed that these are the same as those provided on the
UKERC website. Please see the annexes to the documentation available at
the website you cited
<[2]http://www.ukerc.ac.uk/support/tiki-inde...>.
The Department does not hold this information in Excel format.

If you have any queries about this request do not hesitate to contact me.
Please remember to quote the reference number 10/0361 in any related
future communications.

Yours sincerely,

Julian Hentschel
