      Hello, we were wondering how much energy does the Pu Ngaol village consume annually?

      Regards,

        Hi Owen,

        Thanks for your patience. The monthly consumption of different households varies. During a most recent scoping interview with the villagers, one it’s 60000 riel, another house it’s 80000 riel, and another is 20000. At this writing, we’re still determining what household size these monthly consumptions correspond to. We’ll update you if we can find more information.

        This electricity cost is a significant portion of income. One household mentioned that in 6 months – 1 year, they make around 100000 – 200000 riel from selling chickens and 600000 from selling pigs.

        I hope this helps.

        Regards,
        Jean

          Hi Owen,

          Following from my previous response to your question, here’s my update regarding the monthly electricity cost per household size:

          60000 riel: 4-person household (couple + children)
          80000 riel: 8-person household (couple + children and grandchildren)

          I hope that helps in your estimation.

          Regards,
          Jean

            Hello, was wondering if you know the average energy consumption of each household in Pu Ngaol, in kwh?

              Hi Duoth,

              Unfortunately, we don’t have any data for the average energy consumption of each household in Pu Ngaol village. We’ve collected a few data with regards to their monthly electricity bills:

              60000 riel: 4-person household (couple + children)
              80000 riel: 8-person household (couple + children and grandchildren)

              According to this 2022 article: “There are currently four types of electricity tariffs for households. It costs 380Riels/kWh from 1kWh to 10 kWh of monthly consumption, 480 Riels/kWh for a monthly consumption from 11kWh to 50 kWh, 610 Riels/kWh for a monthly consumption from 51kWh to 200 kWh and 730 Riels/kWh for a monthly consumption that exceeds 200 kWh.”

              I hope this helps.

              Regards,
              Jean

                Hello, do you have the data of the average earnings of Pu Ngaol villagers?

                  Hi Anne,

                  Unfortunately, we don’t have a data of the average earnings of Pu Ngaol villagers. I found some resources that relates to household income in rural communities, where you can potentially base your assumptions:

                    > Report of Cambodia Socio-Economic Survey 2021
                    > Rural Communities on the Cambodian Central Plain: A Comparative Analysis Based on Five Communes

                  I hope this helps!

                    “There is a wage gap between men and women, with women earning $25 USD per month. In regard to expenditure for energy, currently a 4-person household can spend up to 60000 riel (around $15 USD) on electricity per month, and an 8-person household can spend up to 80000 riel (around $20 USD) per month on electricity, which is a substantial portion of their salary.”

                    I used the information given in the EWB webisite.

                      Page 173 of the PDF seems to give a figure much more than the “$25 USD a month”

                        Hi Lachlan,

                        I don’t quite understand your question.
                        a. Could you point out where the wage gap is mentioned in the design brief/website on our end?
                        b. Page 173 in that PDF outlines labour force, which is population not their wages, which could be helpful? (But again, I don’t quite understand the context)

                        Could you expand a little bit more on your project and what you are working on so we can provide relevant advice?

                        Cheers,
                        Sai

                          Oops, I guess I interperted the PDF wrong, my bad. In the Gender section of “Introduction to Cambodia Context” it mentions that women earn less than men, about $25 USD a day.

                            I am working on a low-cost renewable energy solution and I need to know the energy consumption of the village. Currently I am estimating using the average capacity of a car battery and radio, but there is no data as to how long the car batteries last for the villagers, as well as how they charge them.

                              Hi Lachlan,

                              As Sai mentioned in the previous thread, “could you expand a little bit more on your project”?

                              I’m curious, why do you think using the average capacity of a car battery and radio is a good data to estimate the energy consumption of the village?

                              Regards,

                                Our project aims to supply power to the 50% of villagers without access to the grid, as preliminary estimates show that the power demand would be quite high if we were to supply to all the villagers. We aim to combine solar panels and a pico-hydro system to provide energy supply all year round. We decided to estimate the energy consumption of the village via car batteries as according to design area 4, “commonly available 12V lead acid car batteries are used for lamps and other power needs”. Radios are also the primary method of communication so we decided include those in our energy consumption calculations as well.

                                  The following is an excerpt from our report:
                                  The following calculations will ignore the 50% of villagers who are connected and pay for grid power. Assuming each household has two batteries, an average battery which looks about the same size as one in the pictures provided by EWB has a capacity of 720 watt-hours (Wh). Assuming each household has two batteries, this means there is approximately 39 kWh of batteries to charge. Radios, the primary communication method in Pu Ngaol, last 3 days and two nights per charge. A similar model of radio has a battery capacity of 13.5 Wh. Assuming two thirds of the villagers have a radio, there is around 2.5 kWh in radio batteries to charge. In total, there is around 41.5 kWh of batteries to charge each day.
