Station Service Voltage Transformer (SSVT) is a special class of single-phase high voltage instrument transformer with a power winding and optional metering winding at the secondary. The SSVT is capable of being connected directly to the transmission line and providing 120 to 480 V at the secondary power terminals and 115 V at the metering terminals. The power rating of the secondary is normally anywhere from 25 kVA up to 333 kVA. The SSVT was initially developed as a means to provide control power in a substation without the need for stepdown and distribution transformers. Over time, the properties of the SSVT made it an ideal power source for many different applications. Today the SSVT is being installed in numerous applications around the world. Some typical applications include but are not limited to: remote cell towers, transmission tower lighting, oil and gas, mining projects, substation auxiliary power and rural electrification. In any of the listed applications, it is still necessary to acquire accurate revenue metering for the power companies to charge for power usage. In many cases this requires the installation of instrument transformers to perform the metering. Unfortunately, the metering and power windings of the SSVT cannot be operated simultaneously. When a load is applied to the power winding on the SSVT, a load current is reflected back into the primary winding. This current generates a drop in voltage through the primary reactance and resistance. It is these values which are reflected back into the metering winding. The accuracy of the metering winding will fall out of acceptable limits when the voltage drop is present. This research proposes a new method to provide both power and accurate metering, simultaneously, in a dual secondary SSVT. The accuracy of the metering winding remains essentially unaffected by the load on the power winding if the load is less than the maximum rating of the compensator. The result is a single transformer capable of replacing the functionally of two separate transformers. This new approach will have a broad impact in the development of future substation designs.

In this thesis I study the impact of electrification using solar photovoltaic panels in the rural Ecuadorian community of Las Balsas. Many large-scale development organizations like the World Bank promote small-scale renewable energy technologies like solar photovoltaics as being crucial in helping poor rural communities generate more income. My research however, both in the field and in the literature, shows income generation from these projects tends to be minimal. I find that the introduction of solar electrification is most important for social applications like music, movies, cell phones, and lighting. FEDETA, the NGO that installed the solar photovoltaics, promotes the development project not as a neoliberal market-based income-generation project, but rather as a humanistic improvement in the “quality of life” of local residents. I analyze this goal of the project in light of the development theories developed over the past few decades. I question how well solar photovoltaics fits into the “small is beautiful” appropriate technology sector. While solar photovoltaic systems have the potential to build small-scale islands of autonomous electricity production in a more environmentally sustainable manner than grid electricity based on fossil fuels, I caution that this is not necessarily the most equitable way to provide electricity to the rural poor in developing countries. While solar home systems have much potential to provide (often minimal amounts of) electricity to extremely rural areas, the service provided is in many cases inferior to grid electricity. While solar photovoltaic technology does provide many potential benefits in areas not reached by grid electricity, NGOs and policy makers should be wary of seeing the technology as a panacea for sustainable development. Solar photovoltaics as a technology has a long way to go to provide energy services comparable to that offered by most grid systems. As with any technology its actual use is not predetermined, but rather is influenced by the local social and cultural contexts. / text

The recent awareness created by the UN Secretary General on the need to provide universal energy for all by 2030, which culminated in the declaration of 2012 as the “International Year of Sustainable Energy for All”, laid particular emphasis on the challenge of funding rural electrification in developing countries, and the need for innovative ways and financing options to be developed at national, regional and global levels towards achieving the ‘energy for all’ target of 2030. This research, as part of efforts towards remedying the rural electrification scourge of developing countries, particularly in Nigeria, provides financing options for rural electrification as far as the Nigerian Electricity Supply Industry (NESI) context is concerned. The study does this by first identifying appropriate least-cost electrification supply mode (Grid, Mini-grid and Off-grid), and estimating the financing requirement for providing universal energy access to rural Nigeria by 2030, using a spatial electricity planning model called the ‘Network Planner’. Results from this research shows that by the end of the seventeen year planning period (2013-2030), 98% of currently un-electrified communities will be viable for grid expansion, while only 2% will be mini-grid compatible. This is based on a proposed MV line extension of 12,193,060 metres or (12,193 kilometres), LV line length proposal of 711,954,700 metres or (711,954 kilometres), and an estimated total cost of US$34.5 billion investment within the planning period. More so, a total number of 28.5 million households are to be electrified by 2030, which is equivalent to an estimated 125million people to be provided electricity by 2030.The analysis was done for the 36 states of Nigeria and the entire country, using data from the 774 Local Government Areas of Nigeria. In addition to the Rural Electrification Fund (REF) of the FGN, which gets funding from yearly budgetary allocations from the FGN, fines obtained by NERC, surplus appropriation, interests accruing to the REF and donations from various sources, the following financing options were recommended for rural electrification in Nigeria: The establishment of a Renewable Energy Development Charge (REDC); The establishment of a Rural Electrification Fund Tax (REFT) Law; adopting rural electrification as part of Corporate Social Responsibilities (CSR) for oil and other companies; Exploring the option of Crowd-funding; and Establishing a Renewable Energy Private Equity Fund in Nigeria.
