Batteries vs Batts

**Webinar option available** Network and generation costs of meeting high peak demands is expensive; ensuring reliability with large coal stations is expensive and risky. Demand management and distributed storage can solve the problems of network and reliability. Multi-dwelling communities are being much more strongly influenced by demand charges. Therefore the focus for this project is oncontrolling the loadsto influence the demand charge from community's viewpoint.
Batteries vs Batts

Peak demand is a common determining factor for electrical network infrastructure. About half of the residential tariff goes to maintain the electrical network. As the average household grid energy consumption goes downwards because of rooftop PV systems, peak demand tariff is coming to residents to reflect the true network costs.

An Investment Planning under Daily operation tool (IPUD) has been developed to provide operational guidance and balanced investment decisions by including both energy efficiency and storage options.

Houses or buildings are energy systems; space heating and cooling load is often the largest demand. Building energy efficiency options are often set-and-forget technology with long lasting effects, with little or no maintenance requirements, e.g. ceiling insulation (pink batts) and double-glazing windows. The yearly costs and benefits of these efficiency options can be quantified with IPUD.

Battery investment makes more sense when electricity bill is strongly driven by peak demand charge. Its investment becomes more viable when the operation mechanism ensures the right amount of energy is released back to the customer at the right time. For example, batteries can store daytime excess PV energy and release the energy in the late afternoon to reduce peak demand and charge.

Practical tips will be presented along with photos to show how to save energy and reduce demand at home. Business which can profit from this IPUD tool now will be discussed.
