The National newspaper ran a story today on PNG Power upgrading it’s electricity generation infrastructure (read it below also) and it reminded me of a trip I did to a little town called Moruya, N.S.W. Australia in 2004. A family friend’s company was running some trials through a consortium whose goal was to provide a technical means to extend basic telephone and broadband data networking to service remote rural communities in Australia. The great part about this initiative was that they had communications services running inside existing powerlines. Yes that’s right, voice and data signals traveling within the power cable!
In our case that would mean Telikom running communications services in PNG Power’s power lines to access rural areas in PNG. The PNG Power article, stated that ‘…PNG Power’s maintenance and upgrade programmes include installing of nine hydro units in three locations and 19 diesel units at 15 locations throughout the country…’
Considering that a part of this programme is also for establishing rural electrification, in one hit we could have both power and basic telephony in the rural areas of PNG. The diesel units may be isolated from the main power grids, but why not have Telikom VSAT’s connect in those areas.
In terms of payments the Post Offices, local trade stores and/or churches could be used as payment centres for power and phone bills at the same time. But with a pay-as-you-go system like our current Esi-pay system in the towns. This would ensure that rural people pay for just what they need to use and nothing more. And since you have communications in the villages because of the powerlines you could probably even use your Kundu Card to pay for bills. (And then the internet will also come into demand).
A joint service like this would be some serious ‘power’ to the people! Nothing fancy here just basic telephony and power for a house in the village. I’ve seen this working with my own eyes so I know this is possible, I even called my father in Port Moresby and the service was just like any normal landline. ‘Sigh’…sometimes I wish I was a billionaire so that I could have the power to try these ideas myself.

THE NATIONAL - PNG Power Ltd is keeping its power generating facilities in top form to provide uninterrupted electricity supply to household and commercial users. Although the volume of work involved is large and costly, the power firm is carrying out a major capital works programme to ensure continued power generation.
PNG Power chief executive Patrick Mara told a breakfast forum yesterday maintenance was being carried out to increase the capacities of current power stations so there is enough supply for consumers. For example, the Moitaka power plant has the capacity of 36MW but it is currently operating at 16MW. “Currently, power generation is not enough to meet demand and this is a serious issue,” he said.
PNG Power’s maintenance and upgrade programmes include installing of nine hydro units in three locations and 19 diesel units at 15 locations throughout the country. For 10 transmission lines alone, it will cost the company K10 million. Mr Mara said although “financial performance has improved” the cost of doing business for the power company is way above the K100 million mark due to high cost of diesel prices. “This is a horrendous cost and any profits we make are re-directed back to generating power.”
Seventy two per cent of its income comes from its 80,000 consumers, and 14% from industrial consumers. Under its capital works programme, PNG Power will upgrade its key existing systems generation projects. The key projects are refurbishment of Ramu 1 hydro power station, installation of Ulagunan power station to supply Gazelle area in the New Guinea Islands, Lae power station which will involve the installation of an 18MW power plant and Madang power station which will involve the installation of 4.5 MW power plant.
Refurbishment will take place on transmission lines from Port Moresby to Rouna 2 hydro power station, Ramu to Madang, Ramu to Goroka to Mt Hagen and upgrade of Gazelle transmission line at Warangoi to Kokopo. With substations and switchyards, the Kanudi, Boroko and Konedobu substations in Port Moresby and the substation at Rabaul will be upgraded and the Milford substation in Lae will be refurbished.
The Rouna 2 hydro power station is 40 years old and has a capacity of 30MW. And its refurbishment scheduled for completion in early 2009 is aimed to maintain hydro power supply and decrease reliability on the Hanjung power Kanudi plant. This exercise will cost K118 million. PPL will spend K123 million to refurbish 16MW Yonki Dam power station which will supply the Hidden Valley project. It has 135km 132 kV transmission line to connect to grid and is refurbishment is expected to be completed in 2008.
The Ramu hydro 2 power station has a capacity of 240 MW and it is conditional upon agreement to supply the Ramu nickel project in Madang. A new generation of power plants that will take three years to construct will cost K1 billion. For NCD projects under the capital works programme, it will cost K5 million for a capacity of 5MW.
On the rural electrification programme, the National Government has allocated K65 million in the budget for next year. This year, the power company spent K10 million of its own funds for rural power projects.

Good commentary Masalai. For your information, there have been discussions about putting fibre optic cables over new and existing PNG power lines by PNG Power. It is a real possibility and alot closer to happening than you’d think.

Great to hear A.S. I can’t wait!
I’m not sure I may have explained this properly, but the powerline communications service basically comes out of your power outlets in the wall. So telephone calls are running inside the power cables. It is not a seperate cable or in your suggestion an optical fibre hanging on powerlines. Sorry, just making sure people understand what I’m describing.
I personally like this option because the financial outlay is minimal and it would appaer to be appropriate for the low density levels in the rural market. I would only reccommend Optical fibres on powerlines for small towns and/or as an option to DSL.

Manu, I’ve had a chat recently with some people (Schneider Electric) who are trying to push that product in PNG. The problem in PNG is the frequency needed to have that working and the limited bandwidth you’d get because of that limitation - I don’t understand enough of the technology to give you a better explanation but the PNG power guys thought it wasn’t feasible here. They thought the fiber optic cables would better assist them monitor their power delivery and could be used by Telikom to deliver communication services.

OKay fair enough…it’s nice to know that at least the concept was investigated. I think I understand what you are saying here about limited bandwith. The Australian model that I attended to was located in towns, so I imagine looking at the vast reach required for our rural locations will require more bandwith like fiber optics.
I guess what will have to be done now is to make sure that you have enough happening (consumer base) on the fibre optics to justify stretching it out say from Port Moresby to Abau. If the take up with mobile phones is anything to go by then cheaper internet and just phone calls will certainly do the trick to justify the expense in using fibre.
Thanks heaps A.S. for your contributions, it’s exciting to think about what services are in store for PNG.

Masalai you’re on the right track.
Heres a trial that was done in Oz recently. A whole suburb gets all of its telephone call and broadband internet purely through the power lines:

Thanks Danger, yeah that’s right, your link is for the companies I listed above in this posting.

Whoops, Gotta read the posts more thoroughly!
My Bad.
Still, I’d be interested in finding out the technical reasons that prevent its adoption here. It seems to me a market like PNG should centralise its infrastructure rather than expensively parallelling power, fibre-optic and telephone lines.
One issue that has been a problem recently is stealing of copper wire for scrap. Thats technically and Law and Order problem but widespread fibre optic lines would prevent it happening.

No worries Danger…I’m sure you must be a very busy person.
Well for Communications services, maybe forget widespread fibre and just pump up the power of the mobile GSM networks so that we can have wireless broadband.
But then what about electricty for the people?

Without large infrastructure like powerlines it will be very difficult to give people base power. That is, the ability to have always on 240v current from their powerpoint.
If you want to run devices like ovens, air conditioners or washing machines you really need to be in the national grid. But, thanks to the low power demands of modern mobile phones and laptops renewable energy could be used to keep people plugged into the network for VoIP or www surfing. Things like solar panels, micro-hydroelectric plants, and fossil fuel and fuel cell engines are all portable and could easily provide enough electricity to keep laptops or several phones going all day.
The problem is the high cost of these devices. Solar panels and fuel cells are very expensive. The cheaper option is to buy a diesel generator but fuel prices remain high.

Okay, so what in your opinon would be the best way to approach rural electrification needs?
And what business model do you think would work best in PNG?

I like this concept. Thanks for the infor.
