The expansion is to be done in two phases, the first one with 36 MW being added withing 3.5 years, and the optional second phase with up to 16 MW withing 4.5 years from the start of commercial operation of the first phase. All these plans and the power purchase agreement for the second phase are subject to approval by the government and consent by lenders who will provide financing for the project.

Olkaria III is located in Naivasha, Kenya, and is currently capable of generating 48 MW of power. The first phase of the existing plant began commercial operation in 2000, while the second phase of about 35 Mw, began operation in January 2009.

Nigerian hydropower plant project approved

February 9th, 2010 | Posted in Hydro | Comments (1)

According to local media, the hydropower project planned in the Kaduna State in Nigeria has been approved. The news came right after the country has entered into an energy crisis from shortages of gas, resulting in four power plants getting shut down.

The dam project built for the purpose of water supply, has now been reevaluated to show potential for harnessing hydroenergy and producing electricity. Most of the country's power generating capacity comes from thermal plants which burn gas, so there is a need for diversification in the energy sector in order to ensure a more secure supply of electricity in the coming years.

In this context, Nigeria is pursuing several power projects including wind, natural gas, as well as the National Integrated Power Projects, all totalling in about 1345 MW of power generating capacity. The country's goal is to reach the target of 6000 MW no later than March this year.

RES acquired 300 MW of wind energy capacity in South Africa and enters new wind energy market

January 21st, 2010 | Posted in Wind | No Comments

SA-wind-energy-mapProbably the easiest way to enter a previously untapped wind energy market for any company is to buy pre-allocated wind energy capacity. The model allows a company to invest capital and create a presence on such a market quickly (skipping all the work and waiting on permits and studies), creating opportunity for further engagement. RES has announced the acquisition of 300 MW of wind power generating capacity in South Africa, where the company previously hasn't had a presence in the wind energy market. The acquired capacity is still in the development phase. RES has formed a fully-owned subsidiary in SA called RES South Africa, through which RES will continue the development of the wind facilities to their completion.

RES South Africa is headquartered in Cape Town, and has started building a local team that will work on the development of the mentioned projects, but also assess further opportunities for the company in South Africa.

South Africa is one of the global regions which is expected to experience significant growth in the renewable energy market. The country has made commitments about reaching renewable energy goals in the near future, the consequence of which is the expected growth of the market there. Additionally, South Africa is facing a rapidly growing demand for energy, and needs all the additional sources of energy it can develop to satisfy rising demand.

Kenya's active geothermal capacity at the moment is 167 MW, from three production sites at the Olkaria geothermal field, some 60 km northwest of the capital Nairobi. The country's total geothermal potential is about 7 GW, so there is plenty more to harness in the future.

In order to ensure clean and reliable energy supplies in the decades to come, Kenya is planning to increase its installed geothermal capacity to 4 Gw over the next two decades, according to Geothermal Development Company, a local geothermal energy developer.

In order make this plan a reality, Kenya will need a total of USD 16 billion in private investments and donations. Drought conditions have seriously reduced the country's hydropower potential, otherwise the major source of electricity in the country. This situation has been seen in many parts of the world, such as South-East Asia, where whole regions are now trying to tap into alternative energy sources, to compensate for the drop in hydropower potential.

The first step in the "4 GW from geothermal by 2029" is the development of two more sites in Olkaria, with the estimated combined potential of about 350 MW. This project will cost about USD 850 million, which has been promised as grants and loans by foreign aid agencies. Of the three operational geothermal energy sites mentioned earlier, two are operated by Kenya Electricity Generating Company, and one by the Israely company Ormat Industries.

Two drilling rigs have been hired from Great Wall Drilling Company, a unit of the China National Petroleum Coroporation, for the purpose of digging as many as 50 wells in the area by the end of the year. Kenya is planning to buy its own drilling equipment, again with financial help from outside, this time from France.

If geothermal capacity is going to increase to 2 GW by 2014, Kenya is going to need USD 5 billion. The country still has a low citizens/electrical connections ratio.

Printed solar-powered LED lamps could bring light to 1.5 billion people in impoverished areas

November 8th, 2009 | Posted in Solar | No Comments

Printed solar-powered LED lamps

Frederik Krebs is working on a promising project that could help give light to 1.5 billion people living in impoverished areas with no access to electricity. The trick is in combining PV cells printed on sheets, LEDs and ultra-thin lithium batteries. The problem, however, is in the efficiency rate which at the moment doesn't crosses the 1% mark.

The good thing, on the other hand, is the price, which goes at $7 a piece, promising mass addoption if some large scale program is accepted by the UN and governments of the countries where this technology could be used.

At present, some prototypes of the lamps are being tested in Zambia. During the day, people leave these solar panels laying flat, whereas in the night they roll them up (and secure with snap-button) into a cone-shaped lamp. Great idea and one more proof that the future lies in the renewable energy! :)

In a great PR move which honestly involves doing the right thing on the right place, Kyocera announced that it is donating and installing solar power generating systems to 15 schools in Uganda over the next five years.

The donation package contains 600-watt solar power generating systems including storage batteries, and each system will come with basic equipment to be used in educational activities, such as a TV and lights. The Japanese company will donate and install the systems in three schools each year over the coming five years. The first of such installations was completed at 3 elementary and middle schools in the beginning of September 2009.

This is a big thing for Uganda, considering the fact that only 20% of urban areas and 4% of rural areas in the country are supplied with electricity.

Frost & Sullivan: Biofuels markets in Sub-Saharan African are set for rapid growth

October 3rd, 2009 | Posted in Biomass | No Comments

Frost & Sullivan

The sub-Saharan African biofuels market should experience rapid growth in the next five years, despite serious challenges to its development. The high targets set by the EU and US for the inclusion of biofuels in their fuel supply are a key driver for biofuels projects in the region, along with the intensified government support.

According to the new analysis from Frost & Sullivan titled "Sub-Saharan African Biofuels Market," this market will earn revenues of $26.9 million in 2009 and is projected to reach $229.9 million in 2017.

It's obvious that many countries in the region have suitable climates and available land to grow feedstock. However, delays in formulating and implementing the regulatory framework for biofuels production have been a major restraint for the development of the market. Add bad infrastructure to the mix, and you get the complete picture why it's challenging for biofuels manufacturers to make some serious money.

However, many foreign organisations and local commercial farmers have invested in land or have made agreements with out-growers for growing energy crops and setting up pilot production facilities, ensuring that production can begin once the regulations are in place…

September 30th, 2009 | Posted in Solar | No Comments

Mitsubishi Corporation announced it has officially opened a demonstration solar facility in Tripoli, Great Socialist People’s Libyan Arab Jamahiriya (Libya). The solar power facility was installed as a demo project on the campus of Al Fateh University (the largest in Libya). This is a donation is part of a program being carried out by the University in cooperation with Mitsubishi Corporation in order to stimulate applied field study of new energy. Mitsubishi wants to contribute to the society in the mid and long-term.

The facility consists of a solar power generation device, simulation, monitoring and data processing equipment. It allows field analysis to be carried out involving power generation and climate conditions. Libya has favorable insolation, making solar energy and abundant source of power.

Data obtained through the demo facility, as well as the company's know-how, is going to contribute to raising the level of academic studies at the University, but also to promoting clean energy as the future source of electricity.

Libya is trying to diversify its energy generation portfolio in the future. Even though the country has rich oil and gas deposits, the introduction of renewable energy sources is a long-term strategy that will help the country achieve this goal, as well promote renewable energy in the region.
Additionally, development of solar energy in Libya and neighboring countries will create pre-conditions for the eventual execution of the DESERTEC project, in which all Saharan countries will play a major role.
