Energy efficiency is the most touted and important issue in the consumer, power and global ecosystem. Worldwide energy demand is rising exponentially. While some of the sectors like Transportation, Industrial production have been partially efficient in satiating the needs, sustainability at residential levels should still be considered to be in nascent stages, rising from a lack of technological infrastructure support for users. Taking in context the rapidly increasing energy cost, paired up with the scarcity of energy resources, its economic benefits are multi fold at macroscopic level where national and international goals and laws have to be fulfilled and abided by.
“There is too much Energy Conversation than Energy Conservation. Let’s Walk the Talk“
We at Happiest Minds firmly believe that, as we go forward we should leverage technology to envisage a big change and make a difference in how people live, work and innovate. In India, there is a lot of room for this transformation to happen. Let’s go invent tomorrow, instead of worrying about tomorrow.
Use Case 1: Display the global energy consumption and costs using data from Smart Meter and Metering Operator
The customer is presented with information about the global energy consumption of his/her house. The Smart Meter provides a sub-set of its data, including instant power. This data is dispatched either periodically or upon request. The Smart Meter provides its data to the Home Area Network (HAN) either directly, using its own interface, or through a meter service module where the meter records its measurements in the form of index (one per tariff period type) or load curves. Some Smart Meters also have a switching device to limit the power output in conformance with the contracted subscribed power. It is also equipped with a HAN interface for delivering information (index, tariff period, etc.) to devices in the HAN.
This information may be directly received, treated, stored and displayed on a dedicated display, either in kWh or in €. It may also be collected by a Home Gateway that hosts a Web application collecting data from HAN devices and organizes them for a user-friendly presentation.
Actor 1 is Consumer/Customer occupying the house where electricity is consumed
Actor 2 is Metering Operator, responsible for metering and collecting the electrical consumption data
Actor 3 is Energy Provider, responsible for supplying and marketing of electricity to the consumer
Actor 4 is Energy Service Provider, responsible for supplying and marketing energy services to customers

Use Case 2: Display global and per appliance energy consumption and costs, either realized and/or forecasted
As an extension of Use Case 1, customer is also informed on the energy consumptions of the single appliances along with forecasting of global energy consumption based on statistical analysis of past consumptions and taking into account the main characteristics of household appliances, based on indications given by the user, as well as the season, weather conditions and external temperature.
Call Flow Analysis
Use Case 3: Warn the consumer if available total power (at home) is not sufficient to run a Smart Appliance
If the Smart Appliance can estimate the maximum power that would be consumed during its next cycle and there exists a risk or threat to exceed the threshold of the contracted subscribed power, a warning is emitted and displayed on the appliance or other customer interface(s).
