ANNEX VII
CENTRAL SOLAR HEATING PLANTS WITH SEASONAL STORAGE :
FEASIBILITY STUDY AND DESIGN
*»
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
designs forcollecting ,storing andusing solar energy ;and
toprepare detailed system designs for specific site para­
meters .
Means (<
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 .

The Participants will compile cost andperformance data
ontherecommended collector subsystems and theLead
Country will provide this data foruse inSubtask 1(a).
Initial computer codes andsystem studies from 1(a)will
beutilized bytheParticipants inproviding more refined
inputs torecommendations and data oncollector subsystems ,
asafunction ofoperating temperature ,orientation ,etc ..
The Participants will identify requirements for technical
improvements orcost reduction .

scale seasonal storage will beidentified onaperformance
and cost-effective basis .

The Participants will compile characteristics ofrecommen­
dedheat storage subsystems and theLead Country will pro­
/
vide this data foruse inSubtask 1(a).
The Participants will also identify requirements for tech­
nical improvement orcost reduction .
Participants under this Subtask shall discuss with the
Participants ofone ormore Annexes tothe IEA Implemen­
ting Agreement for aProgramme ofResearch andDevelop­
ment onEnergy Conservation through Energy Storage con­
cerning possible co-ordination ofefforts .With theappro­
val oftherespective Executive Committees ,thePartici­
pants insuch Annexes would enter into awritten arrange­
ment with theParticipants inthis Subtask setting forth
theprecise terms andconditions ofsuch co-ordination .

(d)Heat Distribution System
(Lead Country :Swedish Participant )
The Participants will review heat distribution concepts
andtechnology andthose most suitable forlarge-scale
seasonal storage will beidentified onaperformance
and cost-effective basis .

The Participants will compile characteristics ofre­
commended heat distribution systems and theLead Country
will provide this data foruse inSubtask 1(a).Require­
ments for technical improvement orcost reduction will be
identified bytheParticipants .
(e)Site_Inventory_jmd_Pre!iminarY_Si te_Specif ic_SY.stera_Desi jn
(Lead Country :Swedish Participant )
Each Participant wi ">1conduct aninventory ofpotential
sites ,andwill develop a1preliminary design ,including
cost analyses ,for alarge-scale solar heating plant
with seasonal storage ,for one ormore specific sites .
They will utilize for this purpose therecommended com­
puter programs andoptimized parameters developed inSub­
task 1(a).
Attheconclusion ofPhase 1,allParticipants will meet
toreview thepreliminary site-specific designs prepared
under this Subtask .They will then select those which are
suitable forfurther design and evaluation work .The se­
lected .system designs mayuse existing technology only ,
orrequire improved components (which may bealready un­
derdevelopment orforwhich development must beinitiateq )
Inmaking their selection ofsystems forfurther develop­
ment ,theParticipants will consider thelegal andenvi­
ronmental aspects involved ,aswell astechnical perfor­
mance andcost .TheOperating Agent will prepare agene­
ricenvironmental impact assessment forPhase I(e)
systems .

PhaseII-Detail edSyste mDesign
Following thecompletion ofPhase I,each Participant desiring
tocontinue inthis Task will proceed with thedevelopment of
adetailed system design for specific site parameters and
costing ofalarge-scale central solar heating plant suited to
their needs atapossible site within their country .Two or
more Participants mayjointly develop such adesign andcosting .
Participants not wishing tocontinue inthis Task maywithdraw
upon agreement oftheExecutive Committee inaccordance with
Article 10 (g)oftheImplementing Agreement .
Each Participant 'swork will include theconduct ofexperi­
ments asrequired ,,and ,drawing upon thedata andresults of
Phase I,'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
and cost-effectiveness oftheplant may become the subject of
anew Annex tothis Implementing Agreement .
