Energy: a new demand approach

Energy: a new demand approach

How much is it worth to postpone investments in the electric energy distribution area? Here's the proposition.

I Calculation references.

  • Assume an increase in the load factor of 5% of a distributor to its customers contracted on demand
     
  • Equivalent to enabling the same power grid infrastructure for about 2 years, to serve these customers
     
  • The investment in the power grid infrastructure is USD  0.7  Billion/installed GW 
     
  • The annual amortization of this investment is USD 100 Million/year/ installed GW
     
  • Considering the postponement of 2 years, it means USD 200 Million/installed GW savings

II How to increase the load factor by 5%

  • The proposal is a NWA (non-wire-alternative)
     
  • The power distributor offers a new service: "exchange of differences of contracted demands"
  • Customers who have excess contracted demand with respect to the recorded demand  "post" them on a specially designated transaction platform
     
  • Clients who have an interest in increasing their contracted demands "capture" the existing leftovers, enabling "swaps" with customers in the opposite situation
     
  • It's a zero-sum game.
     
  • Customers gain flexibility to change their contracted demands and this has economic value. 
     
  • The concessionaire postpones investments therefore alleviating its cash flow
     
  • It is a huge "win-win" 

If you would like to know more about this concept, please contact me. I am interested in transferring knowledge of this creation (which I called Demand Exchange) to "make it happen". This solution can be applied universally.

Would this part of it be an instanteous/day-by-day type of exchange, or is this a large overall one-time exchange at the beginning of contracts?

Hi Matt,

The power distribution company compares - each month - the recorded demand (maximum registered demand usually measured in 15-min-intervals with the contracted demand and charges the bigger one. Or it may be a ratchet system that compares the recoeded demand of that month and a % of the maximum recorded demand in a on-year period and charges the bigger one.

So this idea is designed to deal with contraced demand x recorded demand. It means that an energy user (charged by demand) could adjust the contracted demand to be closer to the recoded demand. 

The energy user is always facing changes: type of activity in that specific location, energy conversion processes, retorfits for energy efficiency, intensity of activities in the location usually dependent on the economy's humor and a lot more.

Regulations stipulates stiff conditions to change contracted demands because it is associated with the power distribution CAPEX - accordingly they have the right to get a compensation for it. Usually reducing contracted demands mean wiating several months paying a higher than the recorded demand. The proposed demand exchange is a great solution for the utility comany (since it is a zero sum game) and solution and also for the energy users who will be able to adpat in a more cometitive fashion according to the changes.

Forgot to conclude: given the monthly timefrme power distributions companies record and bill demand the prospoed demand exchange is a place to change contracted demands. So if a company engages in a demand exchange transaction it will become effective for the next billing month.
