Interfaces for the Power Grid

in , , , ,

This week has been crazy busy, but I managed to submit the following to the B2G interoperability group at NIST.

Each interface around each process of the grid should allow bi-directional buying and selling. The interface should support discoverable diversity, allowing the standard to grow over time. Ideally, the interface would be the same for different forms of energy, allowing the same economic interface to be used for buying standard power from the grid, solar energy from the neighbor, or thermal energy from the data center in the basement. I should be able to set my heat pump with gas pack to switch not only on peak efficiency, but on the price for each fuel...

B2B2B2B

Several precise correspondents disagreed with my characterization of the ideal interface on every energy widget as a single Business to Business B2B economic interface. Some argued for Business 2 Machine (B2M) and some argued for Machine to Machine (M2M). A few argued for P2B (Person to Business). I think they all make it too complex, and limit the opportunity for new business models. B2B is meant to liberate new markets, new market entrants, new trading models. Starting with today’s Automated Demand-Response (ADR) interfaces, we get more benefits as we move them from M2M to B2B. People want to be in charge of their own property, so a Business inside the building puts the occupant in control. A business inside the building can only express their willingness to participate with an offer or bid. As not all bids are winning

Business Exchanges on the Grid

in , ,

NIST (National Institute for Standards and Technology) started by making a strong claim for ownership in this area, citing Title XIII, 1305 of EISA 2007. NIST set out an aggressive agenda including a preliminary report at GridWeek on 9/24 and a NIST workshop on developing standards at Grid Interop in Atlanta November 11-13.

NIST wants to have in place tight working relationships with the target SDO’s (Standards Development Organizations) in place before 2009. NIST and the GridWise Architectural Council are working together to direct the standards direction toward e-commerce and interactions with building operations...

Home Automation: Bad choices and poor experiences

in ,
My hydronic system failed this summer. It was time. Spare parts for the boiler, still more efficient than most on the market, are no longer available. It supported a hot water heater, and two zones in my old house. I am splitting out the water heater, moving to a tankless system. While the boilers haven’t gotten better, the price for a boiler almost as good has gone way down; the incentive to put everything on one boiler is gone.
