Dear oh dear! Solar? You were talking about CBM , you don't even know what point you are making yourself - perhaps OLD Bailllie does? If the coal seams are as thick as you we'll have so much gas! Brad stop logging out!!! Stop reading filtered messages!!
Sorry folks I have never been able to treat fools lightly. I forgive first mistakes very easily - we all makes mistakes - but this clown accuses me of changing the subject all the time , talks CBM, I reply on CBM , and he switches to Solar! Everything he accuses me of, applies to him. He thinks I am the stupidest person in the world alongside everyone else!
Message to self - take down LSE as your home page! Stop replying on the wrong thread because you cannot reply to a filtered thread that everbody else ignores! It has RENEWABLE in the subject line. Report multiple usernames to LSE - I have resisted that as petty - but it isn't really!
Listen you silly old ass, solar is renewable and we all know that gas and solar are going hand in hand as the new Energy mix in Botswana. We all got this yonks ago....
Let conversations develop rather than you think you know everything and everyone and everything.....
Donk , just how many times do I have to repeat this before it sinks in?
CBM is not RENEWABLE ENERGY and that is why it is excluded from the talks along with coal and everything else that non-renewable! You're so engaged with off topic stuff that you don't comprehend any posts that have anything to do with TLOU. Non-renewable comprehension!
Jeez Smith, would you please stop your endless rambling and ranting about things you have got zero clue about. Allow a conversation to develop rather than you BradBomb every single topic with your total gibberish ! Some people posting on this board actually know ‘stuff’. You are NOT in that collective.
Shut up and maybe you will learn something you silly old twat !!
Sorry guys, the link is clearly dated 28th July 2016 so far from the future!
50% of 100MW was favourite at that time, hence 50MW - so pure fiction in 2021.
Tlou look, as MM claimed, to be very important to Orapa's plans at some time in the future?
rip Helen McCrory aged 52 who is married to Damian Lewis - I thought I was unlucky but 52? Absolutely awful.
Is TLOU that important?
I have spent 90 minutes looking for a definitive map - an virtual all routes took me to african-energy who charge £80 a map and the online maps are too low definition to blow up!
Lord knows where this comes from but it looks amazing if it is possible!

Hmmm, I notice that a 66Kv link from Mmashoro to Serowe does not appear on the modern map.
When then shifted from 66KV to 132KV to Serowe did they turn off those lines rather than build a substation?
I wonder if we might be well advised to use 66Kv and connect to the Mmashoro spur as well as Serowe?
Or was the 66Kv line omitted from the map in error?
Old Bailllie is the thinker of the Donk trilogy. Donk put up references to 33Kv when he poo pooed the thought of heat loss in Botswana on ADVFN ..... that ridiculous post has been redacted with Donk's "." replacing it. Shame he couldn't redact my reply which included this .....
"Did you do A-level Physics Donk? I did! You don't put up a 33Kv line when 66Kv is planned! I know you don't understand heat loss from past arguments! I daresay you think heat loss is related to Covid-19 cos it features in the formula I-squared * R."
I was ridiculed for calling the generators "turbines" he has ridiculed so many things over the years. No foundation behind any of them!
500Kv+ is clearly an unknown approximation 500KV+- did not occur to me!
That SW power station proposal near Mahalapye is on the route of a 400Kv so that may remainas 400Kw, I grant you.
However, if you look at the 2016 map you will see a 66Kv link from Serowe to Moripule!
And the latest map shows it is now 132Kv!
I NOW WONDER IF WE WILL UP OUR NE TX LINE TO 132KV - the 66Kv may not have been for economic reasons after all ??
33KV has never been on the cards except in Donk's post.
Mr Smith, thanks for sharing your wisdom with us.
I would gently point out that there is only one "500kV+ line" in Southern Africa - that being the line voltage on the Gauteng to Cape Town line currently under construction.
Ohhh... there is no such thing as a "500kV+ line" either. These things come in steps - 400kV down or 762kV up. A 400kV line only becomes economically viable at around 1GW of installed capacity.
Ah well, the role of the praise-singer in the African cultures never demanded intellect or understanding - just unquestioning allegiance and an ability to make much noise
I reduced 10Mw to 2W so 48.5 produces heat loss factor of 2352 - even more compelling!
On the numbers in the last 2 paragraphs...
If we make $100k p.a. revenue from a 1 MW solar PV installation, we'll be doing incredibly well.
Not sure about the solar resource at the site (we know it is good) but check your calcs?
No... it is not that simple. A 66kV connection on wooden poles won't be allowed to upgrade to (say) 132kV or 220kV. The line will have to be upgraded to a higher voltage (to avoid excessive line losses) and rebuilt at some point in the future. That is probably OK though - can't start with the cost of a transmission-level voltage for 2MW to 10MW
I take MM's post to mean that Orapa will want enough gas to power their own generators up to 90Mw.
I'm not going to enter in an argument with anyone who denies that heat loss is a factor in Tx lines.
Serowe to Moripule is limited to 132Kv so for TLOU to send more than 132Kv would be nearly as daft as sending two taxis each day to take one child to school. 66Kv or 132Kv were the options and economics dictated 66Kv.
Regarding heat loss - e.g. 132Kv produces a fourfold reduction in heat losses for the identical KW source.
TG's modest 2Mw reduces the current by a factor of 43.5 compared to the 97 MW as some wanted . That reduces the heat losses by a factor of 1892 - so further savings may well be neglible - further evidence of how the man thinks perhaps?
Ultimately I reckon 500Kv+ across huge pylons bypassing Serowe is likely. Will that be under TG? I'd like to think so but he could be non-exec Chairman by then. That route SW could be rejuvenated?
It's not a big deal to hang some extra wires from the already installed poles, should there be a need more than 25MW later. Another example Tony being thrifty and only spending money when necessary.
The reality is, I believe the company are just clearing all the red tape, all the technical issues, proving the route to market, increasing the assets and then selling the company on for fair price. Tony's an entrepreneur, this is what he does.
The capacity of the BPC at Serowe is limited to 25MW and that has dictated the size of the transmission line from Lesedi. Not such a bad thing as it is cheap whilst also keeping our ambitions in check and hence our immediate capital demands.
An eye should be kept on Vigo Consulting and their twitter feed. This from them yesterday in reply to one of the company's tweets:
“Clock starts ticking to Lesedi becoming a reality.”
@TlouEnergy edges closer to reaching first power at its hybrid #CBM and #solar Lesedi project in #Botswana following tender awards for the construction of its transmission lines and substations.
So they reveal/confirm that the company will lead off with a combined (hybrid) solar and CBM option. That's fine by me, solar being less than $1m per MW installed and returning that in revenue each year. Nice business while dewatering is completed and then CBM rolled out.
Besides, I'm not overly fussed by 'just' 25MW to Serowe (or $25m pa of company making revenue) - the next line is surely going to be north to Orapa and their 90MW of demand.
I think they have stated 25MW. More than enough for the time being and to prove the hybrid generating concept. I'm almost certain when more capacity is needed, it won't be Tlou calling the shots anymore.
5 GW of solar! That is a lot of solar and one assumes it would be PV.
Which is potentially great news for anybody with gas-fired power.
That 66kV line looks awfully small. It won't evacuate more than (say) 30MW. A good start though - one can always build a proper line using the same servitudes later.
Finally, news on the mega solar project plans between Botswana and Namibia. The Americans are all over this project as they look to help with funding and technology. Article taken from FB.
Yesterday (13th April 2021), MMGE Minister Hon. Lefoko Moagi and H.E. U.S. Ambassador Craig Cloud signed a Memorandum of Intent (MOI) to deploy 5 GW of solar photovoltaic (PV) capacity across Botswana and Namibia. The MOI is between Power Africa - a US government-led initiative, Republic of Namibia and it is spearheaded from the United States of America. The goal of the project will be to produce electricity mainly for export across the Southern African region.
Speaking at the ceremony, Hon. Minister Moagi said that he hopes that the project commences at an earliest convenience as it will promote addition of renewable energy into the energy mix; and also bring opportunities for the people such as creation of employment as some of the solar farms will be built in Botswana and some in Namibia.
For his part, Ambassador Cloud said that the project will move Botswana from being over reliant on other countries for energy, to not only being energy independent but being able to export energy, and adding renewable energy to the energy mix.
