[#SmartGrid #スマートグリッド] HANチップをスマートメータに内蔵する必要がある、という提言:


HANをチップ化し、業界での標準化を促進する事には賛成だが、それをどこに入れるのか、については今後議論が起きる、と思われる。 見方によっては、これがスマートグリッドの内在的な問題であって、複数業界の考え方がかなり異なるために、標準化が遅れる可能性が大きい、と言わざるを得ない。 

HANチップの話はその問題が表面化してほんの一例。 今後もっと出てくる可能性がある。

As the United States and Europe work to reduce their dependence on oil, their reliance on reliable, cost-efficient electricity continues to grow. In the 1950s, 40 percent of the U.S. economy relied on electricity; it’s now 66 percent. That number is expected to grow with the continued explosions of electronic devices and should more personal autos and public transportation go electric.

After a century of essentially unchanged technology, experts deem the current technology Grid 1.5, with the initial integration of digital technology having been introduced to the grid, such as smart meters.  Grid 2.0 will be achieved when open standards and smart appliances are widely deployed.

Austin Energy CIO Andres Carvallo says embracing the smart grid isn’t an option; it’s a necessity. He anticipates there will be 50,000 rooftop solar installations and 100,000 electric cars in the Austin area by 2015.  Without a smart grid in place, Carvallo says “the Austin grid would become the biggest fireworks display in the history of mankind.”
Acknowledging the importance of digital energy technology, New Zealand’s Parliamentary Commissioner for the Environment believes that the government should add mandatory smart meter technology requirements to the Electricity Bill.

Commissioner Jan Wright told a Parliamentary committee that contrary to utility suggestions, this is the time to include Home Area Network (HAN) chips in smart meters.
“A HAN chip in a meter provides a basis for consumers to be able to control their own electricity use intelligently,” said Wright, “yet no power company could even offer them to customers today, even at the customer’s expense.”

In June 2009, Wright recommended mandatory HAN chip specifications for New Zealand meters but her report was met with skepticism by the country’s utility industry. The Ministry of Economic Development also took issue with the recommendation, citing estimates indicating limited benefits from HAN-enabled smart meters.

“Australia requires HAN chips by 2013, and New Zealand has a common appliance market with Australia,” Wright said. “Whirlpool in Australia…Whirlpool is aiming to manufacture a million smart clothes driers by 2011 and make all its appliances smart by 2015.”

“The criticism that I want to put the cart before the horse is wrong – it’s the other way round. The HAN needs to come first.”

She also pointed out that New Zealand’s Energy Efficiency and Conservation Authority was requiring that all heat pumps be “smart” beginning in 2013.  onwards be “smart”, giving the lie to claims that smart appliances are not yet coming to market.

Wright was critical of retro-fitting newly installed smart, which would cost $75 – $150 for installers to visit homes, while fitting the HAN device pre-installation costs only $20.

The Electricity Bill is scheduled for its First Reading next Tuesday.
