[#SmartGrid #スマートグリッド] Picowatt社がスマートメータを必要としないスマートプラグを発表

CESでのスマートグリッド関連の発表、いくつかある中で、スマートプラグ関係が俄かに登場し始めている。 電力事業者の設置するスマートメータと連携することなく、家庭なのコンセントを流れる電気量を計測し、ワイヤレス通信でデータを転送する装置の事を指す。 

情報の分析はこのワイヤレス情報を拾ったパソコン経由で専用のインタネットサイトに送られ、分析の結果、電気を止めるなどの指示などをこのデバイスに送ることが出来る。  インターネットサイトはFacebookアプリ経由でアクセスできる。 

問題はどのようなデータに基づいて分析を行うか、と言うところにある。  今は、ユーザが完全にその分析を行うための設定を行うことが出来るが、将来的には、電力会社から電気代の変動予定を収集し、電気代の安い時間帯に電気を消費するようなスケジューリングなどが出来るようになる、との事。 

まず家庭内の電力管理からスタートし、次のステップから電力会社との連携を狙う、という方式はこれから増える可能性がある。 


CES: Picowatt does smart grid without smart meter

LAS VEGAS–Tenrehte Technologies has a grassroots vision for the smart grid.

Instead of relying on a utility-installed smart meter to help consumers ratchet down their electricity bills, the Rochester, N.Y.-based start-up is building Wi-Fi-enabled smart plugs.

A few strategically placed smart plugs, called a Picowatt, will provide many of the benefits promised to consumers by the smart grid, including a real-time read-out of electricity usage and the ability to control appliances from a central point. By having data on electricity usage and the ability to take advantage of off-peak rates, people can make a significant reduction to consumption, studies have shown.

There are a number of companies preparing in-home energy displays that are designed to poll data from smart meters to show, for example, how much electricity different appliances consume. Millions of smart meters are being installed over the next three years, but utilities are being slow with sharing consumption data inside the home over a wireless network, in part because of security concerns.

By contrast, the Picowatt lets individuals set up a home energy monitoring themselves. The smart plugs, which fit over existing outlets, are essentially mini Wi-Fi routers running Linux, each capable of gathering data and controlling devices. People can view data, such as historical energy usage, from a Wi-Fi-enabled PC or through a Facebook application that can be operated from a smart phone.

Tenrehte Technologies executives said they are establishing partnerships with utilities to make rate information available. That would allow a person to schedule an energy-intensive job, such as washing the dishes, to take advantage of off-peak rates.

Another nice feature of the Picowatt is that it will eliminate stand-by power, where electronics such as TVs consume juice even when not in use.

At CES, the company had prototype models available but said that it expects that a smaller smart plug, about the size of an Apple AirPort, will be available in April of this year for $79, sold direct to consumers.
