Q1 : Low income and all other customers would be best served by two options:
A wireless access option from the meter that uses open standards, with a customer portal and customer selected data security requirements (that meets their privacy requirements). This would allow the customer to provide access to meter data to any third-party provider or directly to an appliance with embedded applications that might need this data. Third-party providers like cable, telecom, home security companies and appliance vendors might choose to develop API’s that the customer could authorize and/or prohibit individually with a password based on their own assessment of the value and cost of each application.
One solution would be to publish the price and reliability event signals over a public network/service that could be received through low-cost customer owned devices or through subsidized utility provided control units – not requiring Internet access. Such a solution would also allow entities such as the public broadcast would provide low cost access and would allow third-party service providers and appliance vendors to embed logic or to develop API’s that do not require Internet Protocol (IP).
