New Study Highlights Need for California Market Refinements to Better Harness Clean Energy

A new study, jointly conducted by the California Independent System Operator (CAISO) – the entity responsible for overseeing much of California’s electric grid – First Solar, and the National Renewable Energy Laboratory (NREL), demonstrates the untapped potential of utility-scale solar. The study shows that utility-scale solar can provide key services needed to ensure electric grid stability and reliability – better known as ancillary services – at levels comparable to conventional, fossil fuel driven resources.

California needs to reduce reliance on natural gas for ancillary services

In CAISO’s market, ancillary services are overwhelmingly provided by natural gas-fired resources, and their share of the pie has been increasing in recent years.

This growing reliance on natural gas for ancillary services merits attention for many reasons.   Read More »

EPA’s Greenhouse Gas Inventory Makes Progress but Misses Forest for Trees

In its draft 2017 GHG inventory, published this week, the EPA estimates methane emissions from the oil and gas industry were lower than their previous estimate in the 2016 inventory.

The vast majority of the decrease comes from methodological changes in how EPA does these estimates and does not represent actual reductions from improved industry practices. We expect to see fluctuation in EPA estimates in future inventories as the agency continues to revise their accounting methods; this inventory should not be viewed as the final answer. But, to see the actual trend in emissions, you should compare 2015 emissions to their updated estimate of 2014 emissions, not the estimate from last year’s inventory. EPA estimates a mere 2% reduction in actual emissions, largely attributable to reduced drilling activity and well completions, which is a result of lower oil and gas prices in 2015. This points to the importance of recently enacted regulations, like the EPA NSPS and BLM rule, to drive the much greater reductions needed to minimize waste and the climate impacts of oil and gas.

Congressional Review Act: A Law of Unintended and Long-Lasting Consequences

3802348922_e99184a252_bBy Carol Andress, Director of Legislative Operations, Climate & Air

With legislation flying fast and furious through the Capitol – much of it using new or unusual legal mechanisms – lawmakers today must be doubly mindful of unintended consequences. Case in point: Actions rushed through the House and Senate under an obscure law called the Congressional Review Act (CRA), the details of which can cause deeper, more lasting impact than the simple name implies.

The CRA dates to the 1990s. It says that any rule finalized by a federal agency can be subject to an expedited congressional repeal for 60 legislative days after the agency sends up a copy of the final rule and a report detailing the reasons for its promulgation. Within that window, either chamber can introduce a joint resolution of disapproval – which, if passed by both houses of Congress and signed by the president, effectively voids the rule.

The law sounds simple enough. But it leaves a lot of room for error or mischief. Read More »

Another Study Confirms Methane Problem Warrants Action

natgaswellThis post was update on February 10th.

A new study from the U.S. Department of Energy adds to the large and growing body of research on the problem of methane emissions from the oil and gas industry. Methane is both the main component of natural gas and a powerful climate pollutant – which is why regulators, scientists, and industry all have a vested interest in developing a more complete understanding of how much methane is emitted and from which sources.

Researchers with the Department of Energy’s National Energy Technology Laboratory (NETL) used a life cycle model to integrate data from several of EDF’s methane studies, and estimated that 7.3 million metric tons of methane were emitted along the natural gas supply chain in 2012. This value is about 10% higher than the corresponding estimate in the 2016 EPA Greenhouse Gas Inventory (GHGI), although the difference was not statistically significant (the NETL confidence interval ranged from -20% to +30% of the central estimate).

Trump wants to reduce waste and grow jobs? Good, these methane policies do just that.

Casing-head gas

This post originally appeared on the EDF Voices blog.

Today, lawmakers are using the Congressional Review Act to dismantle common-sense energy policies that can save Americans hundreds of millions of dollars and prevent massive amounts of energy resources from being needlessly wasted.

The targeted policies from the Bureau of Land Management apply to oil and gas companies that operate on 245 million acres of federal and tribal lands. Since 2013, these operators have wasted more than $1.5 billion worth of natural gas that belongs to the American public, with millions in lost royalties as a result.

That comes to more than $1 million every day – hardly what President Trump had in mind when he promised to maximize our natural resources. Read More »

Rollbacks to National Standards Jeopardize California’s Efforts to Reduce Methane Emissions

California’s Air Resource Board (ARB) recently released a strong and likely final draft of new regulations that will reduce methane pollution from new and existing oil and gas facilities across California.

CAOilAndGas

Methane essentially is natural gas — wasting it is tantamount to wasting an energy resource. California producers report losing about 75,000 metric tons of methane every year, while nationally companies on publicly owned lands reportedly waste more than $1 million worth of natural gas every day. Alongside methane, oil and gas facilities also emit a list of toxic pollution like hydrogen sulfide, toluene, xylene, and benzene, all of which can be harmful to public health. Read More »
