PVPLANTWITHSTORAGEINGRENOBLENON-TECHNICALSUMMARY
MAIN INFORMATION
• Subtitle : PV Plantwith doubled sided panels, onsite storage and smart power management onALEC’sheadquarters(ESP’ACEbuilding)
• Principle:ImplementationofaPVplantontheroof
ofthe“ESP’ACE”tertiarybuildingwithsmartpowermanagement and storage features in order self-consumetheenergyproducedasPVsystemsonflatroofs cannotbenefir froma feed-in tarif inFrance.
• WorkProgress?Design is ongoing in 2016, call for offer ,implementation and setup are planned for end2017,monitoringin2018

OPPORTUNITIES, BARRIERS AND SOLUTIONS
Opportunities Barriers/Challenges Solutions
Technical(/Geographical)
• Wide deployment of PV productionin FR from existing building, andespecially tertiary and collectivehousingflatroofs.
• Roughly 15 kWp maximum powercan be installed on, espace , for aproductioncloseto18000kWh/p-y
• Good matching betweenproduction/demand in officesbuilding
• South facing tiltedPVpanels,givingoptimalyields
• Storage can help smart network infacing peak demand, and acceptinghigheramountofpowerlocally
• Projetcostefficiencyrequiresinourcase that 90% of the production isusedinsidethebuilding
• Onexistingbuilding,roofsshouldbeable to carryPVarrays, thiswewillhavetocheckwithinourcase.
• Roof area should be compatible toallowsignificantproduction
• Including buildings on siteproductionin“smartnetwork”
• Implement an on site storage(20kWh capacity required in theproject)
Political/Legal• Increase largely PV production inFrance to reach the “EnergyTransitionLaw”objectives
• In France no specific regulations tomake link between on site storageandexternalgrideasy,especiallyforplant<100kWp.
• Excedent production is difficult todeliver on external grid in case ofonsite storage (national gridoperator impose hard technicalspecifications)
• How to contract with the buildingusers (the savings on the globalelectricity bill should be retributedtotheplantowner)
• Discussions ongoing with NationalGridOperatorENEDIS
• A model for contracting withbuildingusersisunderstudy
Financial/Economic
• in FR costs for classic integratedPVsystemsonbuildingsarearound2to3 €/KWp depending on power(1€/kWp for panels only), 4€/KWpincl. batteries and smartmanagement ( batteries cost about800€/kWhstoragecapacity)
• Pay-back time can be 30 Years ifenergy price increase +3%/yr (15Yearsincl.subsidies)
• A business case can be made ifmaterial prices decrease (panels,batteries) ,and electricity priceincreases (the plant reduces theelectricalbillinalargeramount.
• Who is investingwhen building hasseveraltenants?
• low feed in tariff (5 to 6 c€/kWh incase of production from nonintegrated systemes ( flat roofusuallyareintheseconditions
• lowelectricityprice15c€/kWh• excedent production can not bevalorizedwithfeedintariffs,duetobattery on site, this productioncouldbelost
