Abstract [en]

The Brazilian government aims at universal electricity access. The national rural electrification initiative has provided electricity services to more than 14 million people since 2003, mainly through grid extension. However, the initiative has not been able to reach remote areas in the Amazon, thus requiring a review of conditions for small scale off-grid power generation projects. As a result, new rules established under the national rural electrification program address the design and implementation of off-grid power generation projects with an installed capacity up to 100kW. The objective of this paper is to explore the effects of the new set of rules on the levelized cost of electricity for different power generation solutions in the Amazon. Our study shows that the new rules may be beneficial to isolated communities, as they reduce the levelized cost of electricity, favor renewable energy technologies and may contribute to reduce CO2 emissions. In addition, the new rules may help engage new actors to provide rural electrification of the Amazon region. To fully take advantage of the current scheme, action at local level is required to define the most appropriate model for small-scale power generation projects and establish synergies between concessionaires and local energy providers.

Abstract [en]

Worldwide, policymakers face important challenges in relation to the provision of reliable electricity services in remote areas. Brazil is not an exception. The Brazilian rural electrification initiative Luz Para Todos – LPT (Light for All) has attracted attention internationally due to its ambitious targets and significant achievements in a relatively short period. The initiative has proved effective in its first phase, which has been developed through the extension of the grid. However, there are still important challenges in connection with the operationalization of LPT in remote areas.

The ultimate objective of this research is to propose a pathway to facilitate the achievement of universal electricity access in remote areas within the context of the Brazilian Amazon. The analysis was developed using a Mixed Methods Research (MMR) involving tools such as Causal Loops Diagrams (Consideo Modeller ®) and the energy modeling software for Hybrid Renewable Energy Systems (HOMER ®).

This thesis addresses three key questions. The first question is concerned with the strengths and weaknesses of the national rural electrification initiative. The second question investigates institutional, technology and funding structures that specifically support the Brazilian rural electrification initiative in remote areas. The third question involves the identification of leverage points within these structures.

The study concluded that the existing LPT scheme is not capable of achieving full electricity access in remote areas of the Brazilian Amazon. Important challenges remain when it comes to providing the service to inhabitants of these areas. There is a need to i) adapt the existing institutional structures; ii) harmonize technologies within the regional context and, iii) use government funds more effectively. In line with these challenges, identified leverage points indicate that i) rules guiding the relationship among new agents and communities; ii) implementation of small-scale power generation technologies based on local resources; and iii) optimized subsidies are essential to achieve universalization goals in remote areas.

The research proposes a new pathway to activate the identified leverage points within the institutional, technology, and funding structures of LPT. The pathway requires well-informed decision making for the implementation and operation of off-grid solutions that can help to cover the last mile. Within this context, results of the study are expected to provide insights for policymakers, technology providers, project developers, researchers, and communities in general as they seek to increase electricity access in remote areas.

Abstract [sv]

Beslutsfattare över hela världen står inför viktiga utmaningar för att tillhandahålla tillförlitliga elektricitets-tjänster i avlägsna områden. Brasilien är inget undantag. Det brasilianska initiativet för landsbygdselektrifiering Luz Para Todos – LPT (Ljus för alla) har fått internationell uppmärksamhet för dess ambitiösa mål och de resultat som uppnåtts på relativt kort tid.

Initiativet har visat sig effektivt under dess första fas, som utvecklades genom utvidgning av elnätet. Det kvarstår dock viktiga utmaningar för att LPT ska bli operativt i avlägsna områden.

Denna forsknings främsta syfte är att föreslå en väg framåt för att underlätta att allmän tillgång till elektricitet i avlägsna områden av det brasilianska Amazonas uppnås. Analysen utvecklades genom s k Mixed Methods Research – MMR (blandade forskningsmetoder) vilket inkluderar verktyg som Causal Loops Diagrams (Consideo Modeller ®) och energimodelleringsprogramvaran för hybrida förnyelsebara energisystem (HOMER ®).

Denna avhandling behandlar tre huvudfrågor. Den första frågan gäller styrkor och svagheter hos det nationella landsbygdselektrifieringsinitiativet. Den andra frågan undersöker institutionella, teknologiska och finansieringsstrukturer som specifikt stödjer det brasilianska elektrifieringsinitiativet i avlägsna områden. Den tredje frågan handlar om att identifiera punkter inom dessa strukturer där en hävstångseffekt kan uppnås.

I studien konstateras att det befintliga LPT systemet inte är tillräckligt för att uppnå allmän tillgång till elektricitet i avlägsna områden av det brasilianska Amazonas. Viktiga utmaningar kvarstår för att leverera tjänsten till invånarna i dessa områden. Det finns ett behov av att i) anpassa de befintliga institutionella strukturerna, ii) harmonisera teknologierna till den regionala kontexten och iii) effektivisera användningen av statliga medel. På samma sätt indikerar de identifierade hävstångspunkterna att: i) regler som styr förhållandet mellan nya agenter och samhällen, ii) implementering av småskaliga kraftgenereringsteknologier och iii) optimerade subsidier är nödvändiga för att uppnå allmän tillgång till elektricitet i avlägsna områden.

Forskningen föreslår en ny väg framåt för att aktivera de identifierade hävstångspunkterna inom LPTs institutionella, teknologiska och finansieringsstrukturer. Vägen framåt kräver beslutsfattande grundat på god information för att implementera och operera de icke-elnätsanslutna systemen som kan bidra till att nå fram den sista kilometern. I detta sammanhang, förväntas studiens resultat att bidra med insikter för beslutsfattare, teknikleverantörer, projektutvecklare, forskare, och samhället i övrigt i strävan att öka tillgången till elektricitet i avlägsna områden.
