This question is definitely an important one, as boiling down capacity to an oversimplified single number absolutely undermines the grid's actual needs and can lead to errors in judgement-- false sense of security, not well enough planning, or worse that can leave people in serious danger. The current situation in Venezuela and the recent issues with the grid in Puerto Rico in response to...
Capacity Markets that I'm familiar with contain several types of "Capacity Resources" that range from Large Nuclear and Fossil plants, to smaller generators of varying types (solar, wind, hydro, Biomass, etc), to Demand Response programs, to Batteries and even includes Energy Efficiency measures.
I propose the use of the term “capability” which is a measure of the realistic generation ability over a given period, say a year, relative to the machine’s rating. Capability = (average output at the grid switchyard the machine can provide)/(generator nameplate output). For instance, on average a nuclear plant can be expected to generate at nameplate capacity say 90% of the time,...
Such a great piece, Geary-- I really enjoyed it. Among all of the great takeaways, I think this quote sticks out for a number of reasons “90% of the information used in organizations is internally focused and only 10% is about the outside environment. This is exactly backwards” Changing this way of thinking is no easy task, but can be critical
Geary, This is a great article covering the current state of the power industry. It seems like there is no perfect answer. I would love to hear more from our community. What do you think the solution is and how can utilities play a role?
Geary, interesting article. I've always lacked statistical analysis tools in my toolbox, and reading your contribution here I'm struck by how important they are to designing policy which might most effectively address societal problems of immense complexity and ramifications. About nuclear:
It's definitely important to look forward to the type of infrastructure challenges/opportunities from utilities that you mention, but what about the even more basic ones-- is charging infrastructure in place in Brazil yet? Would most people be able to charge at home or with chargers at their offices? How's that situation currently stand?
Right now an EV owner would have to charge at home (with a few exceptions). There are some demonstration charging stations but one would heva to consider - so far - to have the EV fully charged at home and make sure that the anticipated intenary is within the battery range. Actually just the very well off are able to purchase an EV these days in Brazil.
Well what a surprise, Steve. Day-ahead prices in Southern California dropped four years in a row, 2009-2013, just long enough to make the case San Onofre was no longer "economical". San Onofre would have been very economical now, wouldn't it, with DA gas spot prices at $55/MWh? Except now, San Onofre has been permanently closed. A criminal abuse of captive...
