Abstract [en]

Battery storage has been highlighted as one way to increase the share of renewables in energy systems. The use of local battery storage is also beneficial when reducing power variations in the grid, thereby contributing to more robust and cost-effective energy systems. The purpose of this paper is to investigate barriers, drivers and non-energy benefits (NEB) for investments in battery storage in photovoltaic systems (PV) in the context of farmers with PV systems in Sweden. The study is based on a questionnaire about barriers, driving forces and NEB for investment in battery storage connected to PV. The questionnaire was sent to farmers in Sweden who already have photovoltaics installed and about 100 persons answered, a response rate of 59%. The major barriers found are related to the technical and economic risks of investing in battery storage. One of the main conclusions is that the highest-ranked driver, i.e., to use a larger part of the produced electricity oneself, turns out to be the highest priority for the grid-owner seeking to reduce the need for extensive investments in the grid. The primary NEBs found were the possibility of becoming independent from grid electricity.

Abstract [en]

There is a need to reduce unsustainable use of fossil fuels. Increased usage of renewable energy by combined use of photovoltaic solar panels (PV) with battery storage is one way. Another way is to increase awareness of energy usage and reduce the energy performance gap by building energy-efficient buildings. Buildings have a long lifetime and high energy usage will have an impact for a long time.

Barriers, drivers and non-energy benefits (NEBs) for investments in battery storage in photovoltaic systems (PV) in the context of farmers in Sweden with PV systems was investigated by a questionnaire study. The questionnaire was sent to farmers in Sweden who already have photovoltaics installed and about 100 persons answered, a response rate of 59%.

Among the drivers for investments in battery storage in PV systems in agriculture it was found that the highest-ranked driver, i.e., to use a larger part of the electricity produced oneself, turns out to be the highest priority for grid owners seeking to reduce the need for extensive investments in the grid. The primary NEBs found were the possibility to become more independent of grid electricity.

A method for the building process, called ByggaE, which aims to reduce the energy performance gap, has been developed and described. The method is based on two main processes with activities. Documents that support the activities can be found and stored in the energy documentation, a digital map structure. The two main processes are:

  • The client’s activity to formulate requirements and ways to verify these requirements.
  • The main process for other actors is to identify, handle and follow up risks or critical parts.

An overall relation between the energy efficiency gap and the energy performance gap has been identified. Realistic assumptions and follow-up related to the assumptions are found to be important to reduce both the energy efficiency gap and the energy performance gap.

Abstract [sv]

För att uppnå klimatmålen är det nödvändigt att minska den ohållbara användningen av fossila bränslen. Ett sätt är att öka användning av förnybar energi genom att kombinera solel med batterilager. Ett annat sätt är att öka medvetenheten om energianvändningen med dess negativa påverkan på miljön och uppfylla energikraven för nya byggnader bättre. Eftersom byggnader har lång livslängd ger onödigt hög energianvändning påverkan under lång tid.

 

Hinder, drivkrafter och andra icke energirelaterade fördelar med att investera i batterilager till solel har undersökts i en enkätstudie bland svenska lantbruk. Det kom in 100 svar från lantbrukare som har solel, vilket motsvarar en svarsfrekvens på 59 %.

Den viktigaste drivkraften för att investera i batterilager till solelanläggningen är en högre egenanvändning av el. Detta visade sig också vara högst prioriterat av elnätsägare för att minska behovet av kostsamma investeringar i elnätet. Den största icke energirelaterade fördelen med batterilager är större oberoende av elnätet.

 

En kvalitetsäkringsmetod för byggprocessen har utvecklats och beskrivits. Syftet med metoden, som kallas ByggaE, är att minska skillnaden mellan verklig energianvändning och energikrav i nya byggnader. Metoden bygger på två huvudprocesser med aktiviteter. Beställarens huvudprocess är att formulera krav och metoder att kontrollera och följa upp dessa krav. De andra aktörernas huvudprocess är att identifiera, hantera och följa upp risker eller kritiska moment som kan påverka energianvändningen. Dokument som stödjer aktiviteterna lagras i en digital mappstruktur.

 

Det är viktigt med realistiska antaganden och uppföljning som relaterar till dessa antaganden för att fler lönsamma energieffektiviseringsåtgärder ska bli genomförda och för att de energiprestanda som krävs eller förväntas ska bli uppfyllda.
