Renewable rankings of the G20 nations

The G20 is an informal group of 19 countries and the European Union, with representatives of the International Monetary Fund and the World Bank.

Leaders from the group of 20 developed and developing nations will meet in Los Cabos, Mexico on June 18-19, 2012. While they are preparing for it, Renewable Energy World (REW) gives some interesting statistics of ho these countries are faring on renewable generation and clean energy investment.

Understandably oil wells such as Saudi Arabia would pretty much be uninterested in renewables.


REW noted that although investment is growing, the clean energy sector is still struggling to carve out a larger slice of the overall energy mix. Since 2002, the amount of wind, solar, geothermal, tidal and wave power integrated into the grids of the G20 nations has grown three-fold.

However, this represents just 2.6% of the those nations’ total energy consumption. With the current rate of growth, that would equal less than 4% of total consumption by 2015 and about 6% by 2020. With consumption itself is also expected to grow, any reductions in carbon emissions would be quickly negated.


Set targets and guidelines

NRDC thinks that each member country should:
a) put in place plans to pass laws that would require at least 15% of their energy is produced from renewable sources by 2015
b) have strong commitments to create a framework for cooperation between countries that would help achieve the 15% goal
c) devise monitoring method that will ensure the guidelines are clear and the targets are met.

Geothermal project put on hold?

I posted an article about geothermal power plant soon early this year. This renewable energy project is located in Tawau. Everyone knows that Tawau and the East Coast of Sabah in general is currently facing power supply deficiency and power is partly imported from the West Coast.

Latest news: The geothermal project hits a roadblock. It's a shame that this had happened.

In a not-so-pleasant news carried by The Borneo Post on Friday May 11, 2012, the RM419 million geothermal power plant project has been put on hold by the Tawau Municipal Council (TMC) pending a meeting between TMC and Tawau Green Energy Sdn Bhd (TGE).

Local media were told that the councilors "did not know anything about the project" and TMC as the local authority was also in the dark.

For the record the Renewable Energy project would help the East Coast in addressing the acute power supply shortage with its 30MW initial production due in 2014. Details are as follows:

Location : Apas Kiri, Tawau
Cost : RM400 million (RM419mil as disclosed to TMC during the briefing)
Generating capacity : 30MW
Energy tapping : via 12 wells, 1800m to 2000m deep
Build up area : 20 hectares
Expected completion : 3 years (due in 2014)
Tenure : 21-year REPPA with SESB

Awful, awful mistake: Communication gone to the drain?

It is understandable that the affected community would be duly worried about potential environmental mishaps in and around the site, and in every project (water dam, power plant, nuclear facility, etc) the people must be involved in the initial discussions. They are one of the stakeholders for such ventures, albeit not as direct owners. There are now claims that these villagers were not invited to the briefing. I can't believe it; someone is duty-bound to prove it - hopefully the same local media who reported it will take the initiative.

TMC councilors vehemently denied any knowledge of the project. Read about it here. It is difficult to understand that TMC was not informed of significant development right in front of its door step. The proposed site is just 20km away from Tawau town.

TMC president did not state if he too, was in the dark about the proposal. Therefore, we'll take the news at face value and assume that he was duly informed and invited to some of the more important briefings earlier on. In that case, the onus is on him to inform his councilors.

What has gone wrong with our work efficiency?

Let's say these people (councilors, villagers) indeed know nothing about the approved geothermal power project. Who is at fault then? One would probably be quick to point to TGE Sdn Bhd or even SESB. If it is true that way, then I'll say 'serve them right' for the delayed implementation plus liquidated and ascertained damages suffered as a result.

But I wouldn't really buy it. TGE wouldn't want to trade lack of communication for RM419,000,000.00 worth of investment. For that amount of money, the venture has to be done right the first time. And I believe Ir. Andrew Amalados have thought of this long before anyone else raised the issue.


Get on with the 30MW job

If EIA has been carried out to the satisfaction of all stakeholders, with compensation for the folks affected by the land takingover is clearly spelt out, then let the men carry on with the job. Councilors' doubts can be dealt with at the same time. For all we know, the hu-ha hu-ha among the Counsilors could just be due to mis-information. Provide them with the right information.

The proposed 300MW coal-fired power plant has been cancelled for the East Coast and the 64MW turbine generator at Kubota Power Station is not yet available. Let the works on the 30MW sustainable and greener energy source begin.

Geothermal Power Plant Soon

      Kota Kinabalu: A local company is set to pioneer renewable energy in the State by tapping into geothermal sources in Tawau.

      Green Energy Sdn Bhd (TGE) which inked a deal with Sabah Electricity Board (SESB) on Tuesday, aims to generate in the next two years 30MW of electricity for Tawau and its surrounding areas for up to 100 years.

      Its RM400 million geothermal power plant at Apas Kiri, which will be connected to the Sabah electricity grid, will also be Malaysia's first renewable energy power plant using geothermal energy resources.

      TGE Project Director Andrew Amalados said work will commence Wednesday and is scheduled for completion by December 2014, is one of the cleanest forms of renewable energy with carbon footprints very much lower than of coal, fossil oil and natural gas.

Read the news further at Daily Express.

The four Renewable Energy type that enjoy special tariff system in Malaysia are Biogas, Biomass, Small Hydro power, and Solar PV. The special tariff is an incentive to catalyse the generation of renewable energy. Geothermal power is not one of the renewable energy sources under the national FiT policy.

Geothermal power is, however, categotised as renewable due to the sustainability of the source of thermal energy and it is much greener compared to coal, fossil fuel and natural gas. As such, initiatives by individuals and enterprises in harnessing energy from geothermal quaify for certain financial incentive from the government as well as global recognition by international organisations.

Put in simple term, geothermal energy is generated from the temperature derived from earth. As shown in the above image, high pressure steam is obtained from underground geothermal hot reservoir, is contained and managed, then used too drive the power plant turbines to generate electricity. Recovered fluid is injected back to earth and the cycle is repeated.

The first ever geothermal power plant in the country is being built and operated in Sabah by Tawau Green Energy Sdn Bhd with vital info as follows:

Location : Apas Kiri, near Tawau Hills Park
(about 20km from Tawau town)
Cost : RM400 million
Generating capacity : 30MW
Energy tapping : via 12 wells, 1800m to 2000m deep
Build up area : 20 hectares
Expected completion : 3 years (due in 2014)
Tenure : 21-year power purchase agreement with SESB

30MW is not much compared to Sabah's total current demand of 772MW but it will certainly help in stabilising the quality of power supply in the East Coast. Higher available capacity means lesser interruption of power at the consumer end.

Hopefully so.
