Customer Reliability and System Reliability

Demand Integration is based on the fact that reliability has two sides: “On one side, system crashes are mitigated by a least cost mix of supply and demand risk management tools that may be applied in time and space. On the other, DR is the key to the segmentation of customers supply security (a kind of insurance).”

Demand Response came to public awareness when several large and very costly system blackouts disrupted the U.S., Italy, and other industrialized countries. Those countries have a need for a synchronized power system market architecture and design that minimizes the likelihood of domino like cascading failures. The essential requirements of Ultraquality Transportation and Demand Integration to power system planning, operations and control are key ingredients for significantly reducing blackout disruptive powers, which are not addressed by present utility centered paradigms and IMEUC as shown in Power Markets Essential Requirements and Power Markets Essential Requirements - II, which is summarized by the paragraph:

Mission accomplished!!! [These] are comments received and responded under the article Power Markets Essential Requirements. Readers will find that the two assertions questioned, are certainly true: IMEUC has NO Ultraquality, and NO Demand Integration to power system planning, operation and control. Ultraquality is a system characteristic. The incentive system is spelled out clearly. While IMEUC is technology dependent, EWPC is technology neutral. A standard meter is needed for 2GR to develop their business model innovations. Nothing else is needed to reconfirm the winner in the market vs. market competition, this time based on the essential requirements: Retail Competition with Active Demand and Ultraquality Transportation.

Under EWPC the “Level of [customer] Reliability [is, not just should be,] simply a market factor purchased as needed just like Level of Power etc.” In my [seminal], and only article on EnergyPulse, An Alternative Business Case for Demand Response, I stated: “The business case of Demand Response (DR) is enhanced under free markets, innovation, and probabilistic (risk) mindsets. DR is poised to be the demand side risk management tool to complement the traditional "LOLP" supply side risk management tool. There are two sides on the DR coin. On one side, system crashes are mitigated by a least cost mix of supply and demand risk management tools that may be applied in time and space. On the other, DR is the key to the segmentation of customers supply security (a kind of insurance). Because of its fine grain nature, DR can help mitigate delays (intended or not) of lumpy investments in generation, transmission, and distribution.”

Transportation Ultraquality, a MUST that IMEUC lack, includes a process to perform system adequacy (developing long run systemic risk management) and system security (executing short run systemic risk management) by developing/executing “a least cost mix of supply and demand risk management tools that may be applied in time and space” to implement Demand Integration to power system planning, operation and control.
