ANNEX VII
CENTRAL SOLAR HEATING PLANTS WITH SEASONAL STORAGE :
FEASIBILITY STUDY AND DESIGN
H
Objectives ofTask *
The objectives ofthis Task are todetermine the technical
feasibility andcost-effectiveness oflarge-scale ,seasonal
storage solar energy systems for theheating ofbuildings ;
toevaluate themerits ofalternative large-scale system 1
designs for collecting ,storing andusing solar energy ;and
toprepare detailed system designs for specific site para­
meters .
Means j
i
The task will beundertaken inthefollowing Phases inorder
toaccomplish theforegoing objectives :
Phase I :Literature survey ,development ofsubsystem and
system simulation andoptimization ofcomputer
codes ,selection ofsystem components system op­
timization ,andpreliminary designs .
Phase II :Detailed system designs forspecific site para­
meters
Phase I
Phase Iwill bedevided into five Subtasks .Close co-ordina­
tion ofthework under theSubtasks will bemaintained through
information exchange ,reports bytheOperating Agent andpe­
riodic review meetings ofallParticipants .

ment onEnergy Conservation through Energy Storage con­
cerning possible co-ordination ofefforts .With theappro­

Following thecompletion ofPhase I,each Participant desiring
tocontinue inthis Task will proceed with thedevelopment of

their needs atapossible site within their country .Two or
more Participants mayjointly develop such adesign andcosting .
Participants notwishing tocontinue inthis Task maywithdraw
upon agreement oftheExecutive Committee inaccordance with
Article 10 (g)oftheImplementing Agreement .
Each Participant 'swork will include the conduct ofexperi­
ments asrequired ,and ,drawing upon thedata andresults of
Phase 1,'the selection anddesign ofanappropriate system .
Extensive liaison between Participants will bemaintained during
Phase II.Participants will review alldesigns atsixmonth in­
tervals toassure information exchange andtoavoid errors in
design and co-ordination .
IfthePhase IIParticipants sodecide ,theconstruction of
thesolar heating plant and theevaluation oftheperformance
andcost-effectiveness oftheplant may become the subject of
anew Annex tothis Implementing Agreement .
Ti;je Schedule

theSubtasks (a)-(d)ofPhase Iwill commence three months
after the approval oftheAnnex and will becompleted 24months
after approval oftheAnnex .Subtask 1(e)will becompleted
30months after approval oftheAnnex .Joint Phase ISubtask
meetings will beheld semi-annually .
The time schedule for Phase IIwhich isexpected torun for
18months will bedecided bythose Participants wishing to
proceed toPhase II.Phase IIdesign review meetings will be
held atsix month intervals .

Results
The ;results ofPhase Iwill be :
(a)Aliterature survey ofthecomponents andsubsystems
suitable forlarge-scale solar seasonal storage systems :
*
(b)Ananalytic model forsimulation andoptimization oflarge -
scale solar seasonal storage systems ;
(c)Areport identifying recommended solar seasonal storage
systems ,comprised ofalternate combinations ofrecommended
components and subsystems ;
(d)Recommendations foroptimization ofthedesign parameters
for these systems ;
(e)Recommendations forresearch anddevelopment toimprove
the technical and economic viability oflarge-scale solar
seasonal storage systems ,ifrequired ;
i
Copies oftheabove documents an<^reports will bemade avail­
able toall theParticipants inthis Task inaccordance with
paragraph 5(d)below .
(f)Site inventory andpreliminary system design studies within
each Participant 'scountry toenable adecision tobemade

system design .
The results ofPhase IIwill be :
(a)Afully costed site-specific design ofalarge-scale solar
system with seasonal storage for each Participant 'scountry
orgroup ofcountries .
The results ofPhase IIwill serve asabasis for adecision
bytheParticipants whether ornot toproceed with construction
