Policy priorities for managing T&D evolution.
A pair of myths is driving many investments today—i.e., America’s T&D system is falling apart, but the smart grid will save the day. A new MIT study reveals a more nuanced truth about reliability, efficiency, and plans for new technologies. The most effective policies and investments will focus on solving real problems and delivering tangible benefits.
In the Pacific Northwest, you either spill water or spill wind.
The wind power industry has been up in arms ever since the Bonneville Power Administration earlier this year announced its Interim Environmental Redispatch and Negative Pricing Policy. That policy, applicable during periods of high spring runoff and heavy water flow volumes on the Federal Columbia River Power System, calls for BPA to redispatch and curtail access to transmission for wind power generating turbines, and to replace that resource with hydroelectric power generated via BOA hydroelectric dams, in order to avoid having to divert water through dam spillways, which could threaten fish and wildlife by creating excess levels of Total Dissolved Gas (TDG), which can cause Gas Bubble Trauma. Yet the legal issue remains unclear: Does this practice imply discrimination in the provision of transmission service, or is it simply a matter of system balancing and generation dispatch? In fact, the FERC may lack jurisdiction over the dispute, as it pertains to the fulfillment of BPA’s statutory mandates.
Green energy mandates might overburden gas pipelines.
Market rules could evolve to compensate gas suppliers for pressurizing pipelines when needed on short notice. Enhanced ancillary services will require innovative strategies using line pack in interstate pipelines and stepped up communication among gas and electric market participants to preserve reliability objectives in gas and electric markets.
How merchant funding is remaking the rules for renewables.
Six weeks ago, FERC opened a notice of inquiry to invite industry comments on whether wind, solar, and other intermittent energy sources face unfair obstacles in wholesale power markets. Now assigned their own acronym—VERs, for “variable energy resources”—renewables make up a growing percentage of the nation’s energy supply portfolio. But as FERC notes, they present “unique challenges,” especially in terms of constraints on location and limits on the degree to which system operators can control or dispatch individual VER units. Thus, FERC suggests that certain common rules and practices, such as those for unit commitment, dispatch, and scheduling, might make it overly difficult to integrate VERs into the grid.
Commercialization of methane recovery from coastal deposits of methane hydrates could head off an impending gas shortage.
Perspective
Proper authority and market monitoring and mitigation could make the system work.
In the last few years we have watched appalled as the western U.S. electricity markets collapsed, taking with them the solvency and viability of several very large participants, including the California Power Exchange (PX).
How software controls can bridge the gap between wholesale market prices and consumer behavior.
As ideas go, a microgrid is nothing new. Think of steam pipes for district heating in older urban cores. But add a few software controls, and the possibilities grow.
Some thoughts on who should take the lead and how to set up financial incentives.
One of the most interesting questions that arises from federal restructuring of the electric grid, with regional transmission organizations (RTOs) and a standard market design (SMD), concerns the risk of building transmission in an RTO environment.
