---- — SAFE fully agrees with 350MA that the United States must take immediate steps to address global climate change. However, SAFE believes that the proposed quick-start, high-efficiency natural gas power plant for our city is consistent with the state’s Global Warming Solutions Act and can play a positive role in decarbonizing the electric grid in the three decades ahead.
As a seaside community, Salem should be on the forefront of addressing the climate crisis. If we are to avoid the worst impacts of climate change, including sea-level rise that could risk putting a part of our own community under water, the world must reduce carbon emissions by 80 percent or more by 2050. Like the sponsors of the protest against the proposed gas plant in Salem, we are in search of a viable path forward.
Our vision for Salem includes a large-scale maritime wind farm off of Cape Ann — a project that would become more viable if the proposed Salem gas plant goes forward. And as advocates for solar energy, we are pleased that Salem is one of 15 communities that have been selected for the second round of Solarize Mass.
We also recognize the growing evidence that hydrofracking is severely damaging the environment and people’s lives. We strongly oppose this practice and believe it should be stopped until proven safe. To that end, SAFE supports federal and state regulation of fracking and legislation that forces utilities to prevent chemical contamination of drinking water supplies and to fully address methane leaks in the gas distribution infrastructure.
The “easy” work in reducing emissions has been done here in Massachusetts, with all coal-fired power plants scheduled to close by 2017. Going forward, the choices become more difficult. Among the steps we can take to further reduce emissions in the short run is to replace older gas generation with high-efficiency quick-start plants similar to the one proposed for Salem.
The challenge of renewable energy is that it is intermittent: the sun doesn’t shine at night, and the wind can die down at any time. The older plants that currently power the grid are not good at filling in these interruptions in power production because they take 12 to 36 hours to ramp up to full power. The proposed gas plant for Salem is a much better choice to be paired with large renewable projects because it offers super-efficient generation with the flexibility of being able to increase or decrease power generation in an hour’s time, without having to run any more than needed.
During this recent cold spell, our reliance on the dirtiest fossil fuels — coal and oil — for our region’s electricity has escalated dramatically. This situation underscores the need for gas as a transitional fuel until renewables can take up the slack. Otherwise, we are exposing ourselves not only to the unnecessary risks of rolling brownouts that ISO New England (the region’s non-profit electric grid manager) has so forcefully warned us about in their recent statements, but also a reliance on dirtier fuels that increase our greenhouse gas emissions.
Natural gas power generation is not a panacea, but rather a transitional step. It is a much cleaner-burning fuel and creates fewer carbon emissions than either coal or oil. For gas generation to be part of the solution, however, public policies must ensure that gas extraction and transmission meet the highest standards.
In the next 30 years, we must make major changes in how we generate, transmit and use electricity. Our policymakers here in Massachusetts and in Washington, D.C., need to make a far greater commitment to investing in renewable energy generation and in the national network of transmission infrastructure needed to deliver that power to every community in America. Once that infrastructure is in place, then natural gas generation can — and should — be phased out.
This is a need and vision that will take decades to make real. During this transition we have a choice of relying on older gas generation or upgrading to the latest and most efficient gas turbines that will allow us to introduce more renewables, not fewer, into the regional power grid.
Our goal should be to build a national transmission network powered by thousands of renewable energy projects distributed all over the system. That will allow us to decarbonize our electricity in this country safely and dependably. If we choose not to build high-efficiency gas plants at strategic locations on the existing power grid, we miss the opportunity to create the infrastructure of the future today.
We must recognize that in order to transition from our current electric system to one in the future powered mostly by renewable energy, we need several interim steps. We believe this proposed plant is one of the steps on this pathway to a low carbon future that our region and country must pursue and develop.
We should not let unrealistic, short-term idealism, regardless of how well-intentioned, limit long-term progress.
