A brief primer on variable vs. fixed costs

For those of us in the power industry, media discussions of the economics of power generation reveal an almost complete misunderstanding of how power is priced. Depending on our vested interests, we may find this either frustrating or beneficial -- but in all cases, it's false.

Herewith I attempt to explain from whence the confusion arises -- and why it is so critical for the clean energy community to understand this math and its consequences ... and to more accurately articulate the economics of those options we prefer.

Low-carbon energy solutions in India may depend on Tata

Amid analysis of the G8's latest climate pronouncement, the announcement of India's first national climate action plan received less attention than it otherwise might have. Even in the Indian media, the plan was also overshadowed by the release of a McKinsey & Co. report that projects massive power demand growth in the country -- 100 gigawatts more demand in the next 10 years than previously estimated. Yet the very same day, the government's Investment Commission called the "Ultra-Mega" coal plants that are central to India's strategy to meet that demand a "main reason for persistent capacity shortfalls."

As reported by India's Financial Express, the climate change "National Action Plan" consists of a laundry list of programs to be initiated -- or more likely, repackaged -- on solar power, energy efficiency, agriculture, and a few others. Based on previous performance in the power sector, agriculture seems to be the most promising of those programs (especially considering the Indian government's success in raising productivity during the Green Revolution). One can hope India will have the same success, and be able to utilize the same distribution mechanisms, in efforts to create seed varieties adaptable to drier climatic conditions.

If McKinsey is right, India's demand will soar to 315-335 GW by 2017, from 120 GW installed capacity today. To supply that demand reliably would require over 415 GW of installed capacity -- that's triple what the creaky Indian power sector produces now. And about 10 times what even the dozen planned Ultra-Mega plants could hope to supply.
