Elected officials from the Commonwealth of Virginia joined Panda Power Funds Thursday to break ground on the company’s 778MW “Stonewall” generating station located in Loudoun County, Virginia. The combined-cycle power plant will be one of the newest, cleanest and most efficient natural gas-fueled power facilities in the United States. The plant is expected to enter commercial service on June 1, 2017. The Stonewall project marked the sixth financing of a large scale power facility by Panda Power Funds in a three year period, representing approximately $5 billion in total combined capital. The Stonewall facility itself raised debt capital of approximately $570 million. Panda Power Funds is also supplying equity capital for the power project along with large institutional co-investors, including Siemens Financial Services.

Obama’s altar offering
On: 05-08-2015 Topic: General

President Barack Obama is mandating even steeper greenhouse gas cuts from U.S. power plants than previously expected, while granting states more time and broader options to comply.

energybiz reports the tweaks to Obama’s unprecedented emissions limits on power plants aim to address a bevy of concerns raised by both environmentalist and the energy industry in more than 4m public comments received by the Environmental Protection Agency.

The Murray Energy Corporation, a coal mining company, announced Monday it would sue and a number of states and other companies were expected to take similar action.

Senate Majority Leader Mitch McConnell, a Kentucky Republican, vowed to use legislation to thwart the president.

“President Obama will deliver another blow to the economy and the middle class,” McConnell said on the Senate floor.

Some of the changes Obama is making in the final version of the plan go even further in cutting the heat-trapping gases blamed for global warming.

Other changes delay implementation and eliminate certain options that states could use to show they’re cutting emissions, making it harder to comply.

A look at potential winners and losers in Obama’s final plan:


WINNERS:

- ENVIRONMENTALISTS

To the delight of environmental groups, Obama tightened the emissions requirements in his final plan.

That means power plants will have to attain an even lower level of carbon dioxide pollution to be in compliance.

Obama’s proposal from last year set the target as a 30% nationwide cut by 2030, compared to the levels in 2005.

His revamped plan calls for a 32% cut in the same time period.

Left unchanged is Obama’s overall goal for US emissions cuts from all sources of pollution, including cars and trucks.

As the US commitment to a major global climate treaty that Obama is championing, the US committed to cutting its emissions 26% to 28% by 2030, compared to 2005.


- PROCRASTINATING STATES

Many of the complaints directed at Obama’s plan over the last year centered on the amount of time states would have to figure out how to meet their targets.

Plans for how states will comply are technically due next year, but there’s no penalty to asking for a two-year extension, so most states are expected to delay.

Under the earlier plan, the rock-bottom deadline was 2017, but that’s being pushed back to 2018.

And while states previously had until 2020 to achieve their targets, they’ll now have an extra two years ~ until 2022.


- RENEWABLE ENERGY

Obama’s revised plan relies more heavily on renewable energy sources like wind and solar replacing dirtier coal-fired power plants.

Obama now wants the US to get 28% of its power from renewables by 2030, compared to 22% in his earlier proposal.

In a new element, the administration now intends to offer pollution credits to states that drive up renewable energy generation in 2020 and 2021 ahead of the compliance deadline.

States that invest early in wind and solar can store away those credits to offset pollution emitted after the compliance period starts in 2022.


LOSERS:

- NATURAL GAS

The earlier version of Obama’s plan sought to accelerate the ongoing shift from coal-fired power to natural gas, which emits far less carbon dioxide.

But the final rule aims to keep the share of natural gas in the nation’s power mix the same as it is now.

EPA Administrator Gina McCarthy said government estimates show renewable energy has ticked upward even since the rule was proposed last year but that natural gas remained an important part of the US energy mix.


- ENERGY EFFICIENCY

Under the revamped plan, state energy efficiency efforts are no longer factored into the individualized reduction targets being assigned to each state.

In other words, what states are already doing to reduce energy demand won’t be included in their baseline the way that other measures, like replacing coal plants with cleaner sources, will be.

That means some states could face more stringent targets despite their efforts in the past to cut down on electricity use.

But states will still be able to get credit for energy efficiency programs when it comes to meeting their targets in 2022.

The revised power plant rule also offers polluting credits to states that deploy energy efficiency programs in poorer communities.


INCONCLUSIVE:

THE POWER BILL

Although the administration predicts the plan will actually lower the average US energy bill by almost $85 in 2030, companies that produce and distribute electricity aren’t buying it.

The savings come largely from increased use of wind, power and hydro plants, which operate at a cost of close to zero after they’re installed but cost a lot to get up and running.

The administration is also counting on people’s power bills going because they’ll simply use less power as a result of efficiency measures.

The National Association of Manufacturers, the American Coalition for Clean Coal Electricity, the National Mining Association, the American Energy Alliance and the National Rural Electric Cooperative Association all predicted the rule would drive electricity bills up.

But the Georgia Tech School of Public Policy and the research firm Synapse Energy Economics have published analyses of the proposed rule that back up Obama’s claim that power bills will go down.

UK wind power generation soared in the second quarter according to the latest British Department of Energy & Climate Change figures. Highlights for the three month period April to June 2015, compared to the same period a year earlier include, that wind power generation by major power producers increased by 61% to 6,9bln kWh. Offshore wind generation in the second quarter 2015 was up 70% (+1.5bln kWh) compared with a year ago, while onshore wind generation was up 53% (+1.2bln kWh). This is due to an increased capacity of wind farms and an average wind speed increase of 1.3 knots. Overall renewable power generation rose by 58% with growth in biomass.
