Transforming the Electric System to Reduce Costs and Pollution

electrical-power-linesBy: Beia Spiller and Kristina Mohlin

Electricity markets around the world are transforming from a model where electricity flows one way (from electricity-generating power plants to the customer) to one where customers actively participate as providers of electric services. But to speed this transformation and maximize its environmental and cost benefits, we need to understand how customer actions affect the three distinct parts of our electric system: generation, transmission, and distribution.

Largest Methane Study to Date Confirms We Need to Do a Better Job Checking for Methane Leaks

By Matt Watson and David Lyon

Drive by an oil or gas well pad, and it may not look like much — a couple of storage tanks, some pipes, maybe a see-sawing pump jack. But fly over one of these facilities with an infrared camera and you might see something different: methane pollution.

We did exactly that for a new study accepted today in Environmental Science and Technology. In the largest sample size of any methane emissions study to date, we hired one of the nation’s most experienced leak detection companies to fly a helicopter over 8,000 well pads in seven regions across the country using infrared technology to capture images of methane and other pollutants. The goal was to better characterize the prevalence of “super emitters” – the large, enigmatic sources responsible for a big portion of industry’s methane pollution – so we could figure out how to stop them.

Pipeline Safety Bill Puts New Focus on Aging Gas Infrastructure

9496055390_6ce041c81b_oLast month, the U.S. Senate unanimously passed the SAFE PIPES Act, reauthorizing the Pipelines and Hazardous Materials Safety Administration (PHMSA). Tucked inside the bipartisan bill are important new measures intended to advance the ways in which regulators facilitate the repair and replacement of old, increasingly leaky pipeline systems.

The bill also creates a multi-agency task force looking into the health, safety, environmental and economic impacts of the four-month disaster at the 70-year-old Aliso Canyon natural gas storage facility – and what should be done to prevent another one like it.

Aging pipeline systems are a huge challenge. Besides safety concerns, the cost of lost gas is a needless burden on ratepayers. And regulators are also growing increasingly concerned about the climate impact of leaking methane, the main ingredient in natural gas. Read More »

Moving Up: New Accounting Shows Full Scale of Aliso Canyon and U.S. Methane Leaks

rp_AlisoCanyon4-300x209.jpgA paper today in the journal Science, estimating emissions from the massive methane leak at Aliso Canyon, indicates that nearly 100,000 metric tons of methane escaped into the atmosphere over Southern California – more than previous estimates. The new findings come days after the Environmental Protection Agency released draft results of their updated accounting of methane emissions from the nation’s oil and gas supply chain that shows that emissions are up 27% above the agency’s early estimate.

The more we know about methane emissions, the higher they get. The new findings show not just the massive scale of the oil and gas industry’s methane problem, but also how critical it is to get the science right to both understand this source of a potent climate pollutant and reduce it. We know that cutting methane is one of the fastest, most cost effective ways to curb today’s warming, and when combined with critical efforts to reduce carbon dioxide pollution, substantial climate progress can be made.

Coming Soon: Solutions for Finding Methane Leaks Faster

porter-ranch-aliso-canyon-methane-gas-leak-3-1020x610After more than four months of spewing potent methane pollution, the massive Aliso Canyon gas leak has finally been plugged. But now the state of California and the utility that owns the site, SoCalGas, are left with the responsibility of ensuring a disaster like this doesn’t happen again.

While Aliso Canyon has captured the attention of the nation, it’s important to remember that there are smaller—and far more prevalent—leaks happening throughout the country’s oil and gas supply chain every day. In fact, those emissions add up to more than 7 million metric tons of methane pollution every year.  That equals over $1 billion worth of wasted natural gas at 2015 prices. Read More »

EPA Draft Says Oil & Gas Methane Emissions Are 27 Percent Higher than Earlier Estimates

2014EPAInventory2Methane emissions from the oil and gas industry are significantly higher than previous official estimates, according to draft revisions of the U.S. greenhouse gas emissions inventory released Monday by the Environmental Protection Agency. At 9.3 million metric tons, revised estimates of 2013 emissions are 27% percent higher than the previous tally. Over a 20-year timeframe, those emissions have the same climate impact as over 200 coal-fired power plants. The lost gas is worth $1.4 billion at 2015 prices.

The big jump makes it crystal clear that there can be no more excuses for ignoring this huge challenge – not only controlling methane emissions from future sources, as proposed new EPA rules will do, but also controlling emissions from the tens of thousands of leaking facilities already operating now. Existing systems account for all of today’s emissions, and will generate the lion’s share of pollution for many years to come, yet federal rules so far don’t apply to them. Read More »
