Ted Click of Chesapeake Climate Action does you the favor of boiling the massive, 946-page American Clean Energy and Security Act (ACES) down into one concise summary post. Smart Grid has but one tiny mention, but you'll note that in order to hit many of the efficiency and renewable energy targets (e.g., states @ 20% by 2020), smart grid technologies will have to be widely deployed by then.
RE: smart grid security - ACES calls out a requirement for grid cyber security only once, on page 139. But other legislation is growing in the House and Senate to bring much greater grid and smart grid security to bear via amendments to the Federal Power Act. More on that in subsequent posts.
