Off shore will never be a cheap as onshore wind and solar pv. But there are reasons to do it as the generation profile is different from onshore. India has an impressive coastline and majority of states will have access to this power. From the GJ & TN offshore feasability reports the wind dip co...

Re: India's Power Sector

If the environment brigade does not object then just 84 of these turbines each generating 12 MW will be enough to generate the proposed 1000 MW. Unlike the onshore turbines which max out at 3 MW, the offshore ones with longer blades and bigger rotors come in capacities of 8 MW and up. It is propose...

Rs 5 or 8 cents / kwhr should be possible for first round. Ultimately should get to the Rs 3 level. Rope in some privat...

This is the big reason why per unit rates of solar are falling in India, and elsewhere across the world.

Re: India's Power Sector

One thing to keep in mind is that the base of the graph Guru Shetty posted starts at 14000 MW. Not zero. It also does not show the roughly 5000 MW of rooftop solar behind the meter. What this means is that there is a lot of remaining demand that solar can 'eat into' over time. California also has ab...

Re: India's Power Sector

You should consider that Coal plants really only operate at 50% LF these days. So that 80 MW is closer to 200 MW coal plant. That 15 GW is closer to 30 GW. $760 Million is not a bad price for a 200 MW coal plant. And you avoid all the fuel cost. A 200 MW coal plant would need about 500,000 Tons of c...

Again as pointed out this does not matter. All the costs are already baked in and given in Rs / kwhr. They’re baked in for a given installed power capacity. If your needs for power exceed capacity, then costs go up. Why? If you are worried about the reserve, you are still saving the cost of fuel fo...

The true cost of solar is 3-5 times the advertised price. Not a clue where you are getting this from but it not correct. Assuming only 20 GW solar was installed as of 31 Dec 2017, then we're talking about 14% actual power generated from installed capacity. Again, please correct me if I'm wrong (and...

I think a lot of energy efficiency drives are paying up which shows up as lower demand. All those LED bulbs and TVs are cutting down on the load. That's the conventional view. In which case it may unfortunately be a one time thing. Once inefficiencies are wrung out demand may start surging again. W...
