Six Reasons Why Solar Power Plants are Difficult to Develop in Indonesia

Based on RUPTL PLN 2018, installed capacity of solar power plants in Indonesia is only 78.5 MW. It is the lowest capacity among other type of renewable energy sources. I wonder what makes this happened.

Based on Indonesia vice minister of energy and mineral resources, there are six reasons why solar power plants are difficult to develop in Indonesia. Read More

The First Commercial Wind Power Generation is Build in Indonesia

Last week I read performance report of Indonesia Ministry of Energy and Mineral Resources. Indonesia has succeeded in developing the first commercial wind farm in Indonesia. The wind farm was constructed in Sidrap, South Sulawesi. The capacity is 75 MW, consisted of 30 turbines with capacity of 2.5 MW each. The wind farm can supply electricity to 150.000 houses (450 VA per house) [1].

Sidrap wind farm was sponsored by UPC Solar and Wind Investment LLC, a Delaware limited liability company [2]. The wind farm is operated by PT Sidrap Bayu Energi. The electricity is sold to PT Perusahaan Listrik Negara (PLN) to a 30-year power purchase agreement [2]. Read More

Coal Bed Methane for the Future of Gas Reserves in Indonesia

Coal bed methane for the future of gas reserves in Indonesia is one topic explained in BUMI Bulletin published by SKK Migas (Indonesia Special Task Force for Oil and Gas). This topic is very interesting because I never considered coal bed methane (CBM) as source of gas until now. CBM is hydrocarbon formed and kept in source rock, it does not move or migrate. In Indonesia, CBM reservoir is very wide and its resource and reserve is large.

Renewable Energy Resources: Wave, Tidal, and Ocean Thermal Energy Conversion

The other type of renewable energy resources that come from ocean are wave energy, tidal energy, and ocean thermal energy conversion.

Wave Energy

Wave energy is a type energy obtained directly from surface wave or surface wave under pressure. The waves are generated from winds blowing from the surface of sea or ocean. Wind itself is a function of temperature and pressure differences across the globe caused by distribution of solar energy.

Wave energy carries kinetic energy and gravitational potential energy. The energy is a function of height and period of waves. Wave Energy Converter (WEC) is used to convert wave energy into electricity. Read More

Renewable Energy Sources: Geothermal and Biomass

In previous post, I shared brief overview about common renewable energy sources, such as solar power, wind power, and hydro power. In this post, I want to continue sharing about other renewable energy sources, which are geothermal, biomass, and energy sources from sea (wave, tidal, and ocean thermal energy conversion).

Geothermal Energy

Geothermal energy is renewable and offer more advantages than other renewable energy sources, such as hydro, wind, bio energy, biomass, and wave energy. It has high degree of availability, low land use, insignificant dependence on weather conditions, and comparatively low visual impact.

Global installed capacity of geothermal power has reached 14.4 GW, with the US as the largest geothermal country so far. Read More

Renewable Energy Sources: Solar, Wind, and Hydropower

Renewable energy is increasing around the world. This is because energy from fossil fuel becomes scarce. In Indonesia, based on RUPTL 2018, government plant to increase geothermal energy source from 5% in 2018 to 12% in 2025. The percentage of other renewable energy is 0% in 2018 to 2% in 2025.

What is renewable energy? Renewable energy is generated from sources that naturally replenish themselves and never run out.

Renewable energy could be alternative to combat with climate change because it does not generate direct greenhouse gas emission. The only emission that renewable energy generate is indirect greenhouse gas emission, which are from installation, operation, and maintenance. Read More

Potential geothermal projects in Indonesia

Potential Geothermal Project in Indonesia

Today I stumbled upon Investment Catalog while searching for certain information. The catalog was issued by Ministry of Energy and Mineral Resources, Republic of Indonesia. And guess what? I found something interesting: potential geothermal project in Indonesia.

The catalog was actually 2017 version. However, I think it is still quite relevant.

For you, who are consultant like me, EPC contractors, vendors, or licensors, you may be interested on this information. You can download the publication to read detail information about those projects. In this post, I want to share you potential geothermal project in Indonesia and its status based on publication on media.

There are six potential geothermal projects in Indonesia. Those are geothermal project in Gunung Galunggung , Gunung Hamiding, Gunung Wilis, Gunung Simbolon Samosir, Graho Nyabu, and Gunung Geureudong. Some of the name are familiar for me. Read More
