"Plan A": saving energy use to cut power bills
"Plan B": SHIFTING energy use
- After assessing cost-effective options for energy saving, it is time to evaluate options for SHIFTING energy use.
- The spread between peak period tariffs and off peak period tariffs continues to grow.
- Technology to freeze Phase Change Materials overnight and use them as heat sinks for air conditioners, refrigerators, cool rooms and freezers in peak periods is commercially available. (Freezing a block of ice at off peak tariffs can deliver low cost cooling in peak periods.)
