Load Shifting

*There is tremendous economic potential in load shifting.
 * The peak 2008 demand in California was 48,491 Megawatts.
 * 5% of the peak or 2,425 MW was only used for 15 hours of the year. At $2000/kW the capital cost of this capability was $4.8 billion. 

 * 10% of the peak or 4,849 MW was only used for 55 hours of the year. At $500/kW the capital cost of this capability was $9.6 billion.

F. Demand Response (DR)
updated tuesday, february 2, 2016 
A temporary change in electricity consumption in response to market or reliability conditions

E. BYOD Smart Thermostat
Wednesday, january 20, 2016
Smart thermostats are considered “smart” because they automatically monitor and adjust themselves to better manage energy used for heating and cooling. Customers can control them remotely via Wi-Fi-connected devices such as smartphones, tablets and personal computers

D. Auto DR (ADR)
friday, SEPTEMBER 26, 2014 
Use Internet based electricity pricing and demand-response signals to initiate pre-programmed control strategies that provide fully automated management of building energy use

C. Demand Response Markets
It is estimated that a 5% lowering of demand would have resulted in a 50% price reduction during the peak hours of the California electricity crisis in 2000/2001. With consumers facing peak pricing and reducing their demand, the market should become more resilient to intentional withdrawal of offers from the supply side.

B. Load Management
20% of generating capacity exists only to meet peak demand, so it runs just 5% of the time and provides just 1% of supply. Peak demand reduction could save billions of dollars.

A. Direct Load Control (DLC)
A utility or system operator remotely shuts down or cycles a customer’s electrical equipment on short notice to address system or local reliability contingencies. In exchange, the customer receives an incentive payment or bill credit.

  1. There's still plenty to gain from load shifting. Energy managers are more and more looking into 'load shaping' strategies.
