About 54 percent of the rural population still lacks access to electricity<ref name="INE">INE.2009.Boletín de prensa:En Honduras el acceso a servicio de energía eléctrica se concentra en área urbana. INE. Tegucigalpa, Honduras.2 p.</ref>. In absolute terms, it is estimated that more than 386,000 households or more than 1.93 Million people in rural areas remain without access to electricity. | ||

+ | The national electricity system is concentrated in the western part of Honduras while the sparsely populated eastern part remains mainly beyond economic line-extension distances. The population density in Honduras is about 58 inhabitants per square kilometer. While in the western departments the density reaches proportions of 137 Inhabitants per km<sup>2</sup> (Francisco Morazán) and 306 Inhabitants per km<sup>2 </sup>(Cortés), it declines to 17.5 in Olancho and 4 in Gracias a Dios - Mosquitia, both of them located in the eastern part of Honduras. | ||

+ | In rural areas population is highly dispersed and access to electricity is often difficult (for example, there is only river access to most of the Mosquitia Region). These two characteristics prevent provision of electric services by the conventional grid, and call for site-specific off-grid solutions such as diesel plants, solar or hydropower plants. | ||
+ | |||
+ | Off-grid electrification in Honduras consists mainly of installing diesel minigrids, operated by independent companies to serve some larger villages on the bay islands (Roatán Electric Company” RECO, “Utila Power Company” UPCO, “Bonaca Electric Company” BELCO) and in Puerto Lempira, Gracias a Dios (INELEM and ELESA). In a few cases hydroelectric and solar home systems have been implemented. | ||

+ | Otherwise in-grid electrification in the rural area is characterized by very old network working with secondary circuits which in some cases are too long and cause a large voltage drop and high losses<ref name="ESMAP" />. For the time being efforts to increase the electricity coverage have been hindered due to an inexistent adequate rural electrification approach and policy which could contribute to articulate, the decentralization at a local level, the involvement of municipalities and the private sector, and the use of alternative energy local supplies.<ref name="ESMAP" /> | ||

Energy demand and supplyThe total primary energy offer in Honduras is around 4.62 Mtoe or 53,730.6 GWh[1].The main source of primary[1]energy is petroleum (53%) followed by combustible renewable and waste (44%), and coal (3%). The residential energy consumption[1]is around 47% of the national consumption, of which 86% are provided by biomass, primarily firewood. Gross electricity generation of the national grid (Sistema Interconectado Nacional –SIN) is currently around 6,539 GWh, of which 53% are petrol power plants, 42% hydro power plants, 1% coal power plants, 1% gas and 3% co-generation. The net electricity offer is around 6,494.1 GWh[2]including imports and exports. Consequently, 22.5% of the gross electricity production is lost. The losses are the highest in Central America after Nicaragua and 60% are classified as non-technical[3]. Following a recent study of the financial crisis of the state owned electricity company ENEE; 39% of the non technical losses are caused by fraud, 29% by illegal connections in marginalized settlements, 29% by errors in the billing, 2% by meter calibration and 2% by other causes; approximately[3]. While the illegal connection makes up 77% of the non technical losses caused by the residential sector (in total 39%), the fraud and billing errors occur especially in the commercial and industrial sector (50% of the non technical losses). Besides this, as a result of a special investigation conducted by the Honduran Accounting Superior Court (Tribunal Superior de Cuentas) on ENEE’s direct contracting for the supply of electric energy to the system, have been disclosed to a broader audience a comparative analysis of the generation costs of thermal plants as well as the irregularities that ocurr on direct contracting processes. Among other aspects, this investigation concludes that the energy price offered was calculated considering the coal cost in one case 64% higher and other case 39% higher than international market prices.[4] These losses as well as these higher energy prices limit the ENEE to invest in social electrification projects or expand infrastructure. The installed capacity increased from 565 MW in 1994 to 1,605.79 MW (not firm) in 2009 while the demand increased from 453 MW to 1,203 MW in the same period[2]. According to the National Expansion Plan 2007-2020 expected demand growth is 5.7% annually[5]. For this reason, the contracting of 250 MW from renewable sources generated by private companies, which at the moment has been discussed by the National Congress; as well as the planned interconnection of the six power grids of the Central American countries (Central American Electrical Interconnection System), could contribute to meet demand growth for the future. Energy demand and supply in the household sectorAs mentioned before, the main energy source for the residential sector comes from firewood, particularly in rural and peri-urban areas. The main use of this firewood is cooking, and in some cases lighting and heating. It is estimated that a household, without access to electricity, uses approximately 525 kg of firewood per year.[6] Taking into consideration the total population without access to electricity in Honduras, that would means 11 million m3 per year.The calculated demand increased of firewood is 2.96% annually.[6] The main source of firewood in Honduras is the forest. Due to this, the extraction of firewood is considerate one of the causes of deforestation at the national level[7] . Some studies indicate that between 1990 and 2005, Honduras lost 37.1% of its forest cover, or around 2,737,000 hectares . Despite this, 59% of its territory today remains covered by forests, but the estimated annual rate of deforestation of 62.000Ha/a.[8] boasts a fast reduction of this resource in Honduras. Under these circumstances, to make the use of firewood more efficient becomes a necessity thus to contribute to the reduction of the current actual rate of deforestation. One example is the use of improved firewood stoves. With these approximately 70% of the firewood is reduced in comparison to the traditional stoves. In addition to the reduction of the firewood consumption, there are other advantages for use of these stoves such as: more efficient use of heat, reduces the smoke in the kitchen which in turn reduces respiratory diseases by the inhalation of smoke, and improves hygiene in the home.[6]
