DESCRIPTION
Inadequate feasible implementation models for sustainability , especially if the programme or project is Government-subsidised .
Most load demand assessments are conducted on assumptions about the hourly use of each appliance in a day . This approach is common practice as real load demand is rarely available on site . Thus , this could sometimes lead to an oversized or undersized system capacity .
Several stakeholders , such as the Government and private companies ( e . g ., utilities ), may be involved in several REP initiatives , which could lead to problems in co-ordinating them . Some may take credit for political mileage . Commonly , it is the quantity of implemented systems that is highlighted the most , while the quality of services once a system is operational , is neglected .
The concerned stakeholders , especially the consultants and project implementers , must have sufficient know-how in designing a system by adapting to social , economic and technological aspects .
Conflicts abound between making returns on investment , in particular if the project is privately financed , and ensuring affordable tariff rates which customers can pay , as most communities in rural areas are poor . Although there needs to be schemes that are suitable and affordable , financial institutions are reluctant to implement them in order to avoid the failure of REP initiatives .
Local conditions , such as weather and geography , must be taken into consideration at the very beginning of project planning in order to avoid delays . Involving local communities and understanding local culture are also essential .
Some rural areas will probably be supplied with electricity from the grid network in the future . It should be possible to integrate the chosen technology into the electricity grid network . Good coordination and planning among the electricity utility companies are crucial .
In many cases , land acquisition and ownership issues are challenging and time-consuming . The installation of a power supply system requires land , which could raise public concern and conflict with the land owner .
Regulatory enforcement and product standards need to be addressed clearly to ensure quality . Negligence in enforcing regulations can result in poor system performance and give a bad reputation to renewable energy technology as a whole . Costs of renewable components do not reflect retail prices . Non-existence of standard prices as references can be manipulated resulting in higher rates .
