TCPI GROUP has built exceptionally high quality buildings and long lasting client relationships. We have a superior reputation for bringing projects in budget, often when other contractors can’t or won’t. We work with the design professionals to identify alternatives for the systems and materials going into the final design. By considering these “Cost Savings Alternatives” in the course of design, we are able to incorporate the most cost effective means, methods, systems and materials into every building we construct.

Renewable energy;

Hydropower has dominated renewable energy investment across the continent, but current projects (with total capacity of around 24 GW) only generate 5% to 10% of the total technical potential, equivalent to 10% to 20% of the total economically feasible potential, according to IRENA. In turn, the onshore wind resource in Africa is in the order of 1,750 GW, significantly more than the continent’s electricity demand for the foreseeable future. Furthermore, the availability of high-quality geothermal resources in Africa is limited relative to that of wind and solar, but the potential is still in the order of 7 GW – 15 GW. Geothermal resources are concentrated in the East African Rift, especially in Kenya and Ethiopia, and could provide an excellent source of low-cost, baseload electricity. Looking at geothermal, Kenya is now the 7th highest producer of geothermal power globally after it recently unveiled the second phase of the Olkaria geothermal plant, which added an extra 140 MW to the plant’s capacity. Olkaria is now the biggest singleturbine geothermal plant in the world, with a capacity of some 280 MW. Kenya is among the world’s most active regions for geothermal development, and figures from the national statistics bureau show that 381.6 MW of geothermal power was generated in December alone. Due to the poor rainfall in recent months, geothermal now accounts for an estimated 51% of the national generation mix, displacing hydro as the country’s primary energy source. Kenya has since submitted a bid to host the global geothermal summit in 2020, and is competing with United States and Japan, among others. The East Africa region more generally will be a key focus for geothermal development, with Ethiopia, Tanzania, Rwanda and Uganda all pushing similar geothermal programmes. Despite recent developments in geothermal energy in East Africa, many of the largest renewable energy projects relate to harnessing the potential of Africa’s great rivers. Many African countries have exploited their good relations with China to make use of Chinese knowledge in dam building as well as Chinese funding to fund these hydro energy projects. The Ethiopian government has been particularly active in this area, with major projects involving most of the rivers flowing through the country – most notably the 6,000 MW Grand Ethiopian Renaissance Dam (GERD). Uganda, Mozambique and Ghana are also among countries that have major hydroelectric schemes under way or planned. However, the most ambitious of hydro energy projects on the continent is the Grand Inga hydroelectric project in the DRC. Grand Inga will generate 40,000 MW, and will be constructed in six phases, the first of which being the Inga III dam. The dam is a priority project for a number of African development organisations, including the New Partnership for Africa’s Development (NEPAD), the Southern African Development Community (SADC), and the East African Power Pool (EAPP). While South Africa and the DRC signed a cooperation treaty to jointly develop the Inga III dam in May 2013, construction is planned to commence only in 2016. Furthermore, solar power is the most widely available source of renewable energy in Africa, with most countries on the continent boasting significant solar potential. Many African countries receive on average 325 days of bright sunlight per year. This gives solar power the potential to bring energy to virtually any location in Africa without the need for expensive large-scale grid level infrastructural developments. The distribution of solar resources across Africa is fairly uniform, with more than 80% of the landscape receiving almost 2,000 kWh per square metre of solar energy per year. Africa currently has one utility-scale photovoltaic (PV) plant (generating 7.5 MW in Cape Verde), and while the total installed PV capacity in Africa

Electricity generation;

Electricity generation varies significantly between African countries. The continent’s two largest electricity generators, South Africa and Egypt, accounted for nearly 60% of the continent’s total generation in 2012. In turn, the 27 countries with the worst generation figures on the continent, representing more than half the countries in Africa, only contribute around 1% of the continent’s overall generation. North Africa dominates the continent in terms of electricity generation from a regional perspective. However, South Africa remains the continent’s largest electricity producer, alone accounting for around 35% of Africa’s electricity generation. Other notable producers include Mozambique, Zambia, and the Democratic Republic of Congo (DRC). It should be noted that the extractive sectors play dominant roles in these economies, and much of the generated electricity directly flows to these operations, bypassing a significant part of the population. Furthermore, East Africa’s most developed economy, Kenya, as well as Ghana on the west coast of Africa perform commendably in terms of electricity generation in an African context. However, with an estimated annual per capita electricity usage of 150 kWh in Kenya and 342 kWh in Ghana, the countries perform very poorly when considering the estimated global average annual figure of 2,550 kWh
