EXECUTIVE SUMMARY

▪ Large energy buyers—including corporates, cities, and institutional customers—have played and will continue to play an important role in driving clean energy in the near term, particularly renewables. However, to ensure that the power sector achieves deep decarbonization over the next two to three decades, large energy buyers will need to take additional actions to play a leading role in accelerating the transition to a carbon-free grid.

▪ Large energy buyers can implement approaches that help transform the grid such as matching clean energy purchasing with the timing of their energy use, incorporating demand flexibility, purchasing dispatchable clean electricity, adopting enabling technologies (e.g., energy storage), maximizing emissions reductions, and driving an an equitable transition to clean energy.

▪ There is no single strategy for implementing transformative procurement practices, which is why we have
highlighted a variety of approaches in this issue brief. Optimal procurement approaches can vary based on differences in customer electricity usage, market context, available product offerings, staff and resources, and differences across grids.

▪ To enable large energy buyers to implement transformative procurement practices, new products and solutions will be needed. Metrics and recognition programs will also need to be revised to incentivize and encourage more customers to take actions that can facilitate a carbon-free grid.

NREL

Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs. The projections show a wide range of storage costs, both in terms of current costs as well as future costs. Although the range in projections is considerable, all projections do show a decline in capital costs, with cost reductions by 2025 of 10-52%. The cost projections developed in this work utilize the normalized cost reductions across the literature, and result in 21-67% capital cost reductions by 2030 and 31-80% cost reductions by 2050. The cost projections are also accompanied by assumed operations and maintenance costs, lifetimes, and round-trip efficiencies, and these performance metrics are benchmarked against other published values.

Green Energy Is Finally Standing on Its Own Feet

Next to a wheat field north of London, banks of solar panels in 35 neat rows are generating electricity without any support from the government.

Despite Britain’s reputation for grey skies, the closely-held developer Anesco Ltd. is building the hybrid solar and battery facility in Milton Keynes with its own capital. It’s just one of about 15 photovoltaic projects underway from Italy to the U.K. that aren’t relying on subsidies to make a profit, according to Bloomberg NEF, which anticipates many more to come.

Vietnam’s plan to pilot a direct power purchase agreement for renewable energy in 2019 has drawn keen interest from investors.

On June 12 this year, at a seminar on renewable energy, the Electricity Regulatory Authority of Vietnam (ERAV) discussed and disclosed information about such a pilot DPPA.

Generally, a DPPA is an agreement between a power generator and a corporate customer in which power is physically delivered and sold to the customer for its operation.

and Angus McCrone, Chief Editor
Bloomberg New Energy Finance

At the beginning of 2017, we drew an analogy between the clean energy sector and the great explorers of the 15th and 16th centuries, embarking on epic journeys, driven by the scale the opportunities they knew awaited them, but facing quite extraordinary danger and uncertainty.

Well, our battle-hardened fleet managed during 2017 to make some good progress towards Eldorado, despite all the storms thrown at it.

2017 looks certain to be the eighth successive year in which global clean energy investment has been in the range of $250 billion to $350 billion; there is a good chance that it will end up a touch higher than last year’s figure of $287.5 billion. Once again, we have seen substantial reductions in the cost of renewable energy, so that 2017 will certainly see another record for new capacity installations.

Motorists can charge their vehicles automatically in less than a minute with the battery-swapping system.

adb.org_Imagine you’re buying a car, and the manufacturer forces you to purchase not only the vehicle itself but also demanded you pay upfront for 10 years worth of fuel. About $25,000 for the car and another $50,000 for the gas. Would you still purchase the car? Absolutely not, unless the gasoline was given at a discount price, right?

Anyone shopping for an electric car could be forgiven for thinking that manufacturers are asking to pay upfront for future energy use. These vehicles are still on average about 35% more expensive than non-electric cars – despite gradually declining battery prices and the promise of practically zero maintenance fees.

A surge in renewable energy is another threat to the black stuff’s future

From the print edition | Finance and economics

Apr 1st 2017

economist_THE Hazelwood power station in Australia’s state of Victoria started generating electricity 52 years ago. The stark symbol of an era when coal was king, Hazelwood was one of Australia’s dirtiest: its fuel was the Latrobe valley’s brown coal, a bigger polluter than the black sort. The station was due finally to close on March 31st. Days earlier, chimney stacks were demolished at Munmorah, a black-coal station north of Sydney, already closed. Australia has shut ten coal-fired power stations over the past seven years, yet coal still generates about three-quarters of its electricity.

The ECOreport interviews Laszlo Varro, Chief Economist of the International Energy Agency (IEA) about energy investments in a transitioning world

By Roy L Hales

Though most of the world’s energy investments are still in fossil  fuels, their iron grip is weakening. The largest source of power investment was the $313 billion put into alternate energy sources like wind and solar. According to Laszlo Varro, Chief Economist of the International Energy Agency (IEA), last year there were more renewables coming online than the entire growth of the energy sector. In many developing countries, wind and solar are less expensive than using imported gas to produce electricity. Laszlo Varro, Chief Economist of the International Energy Agency, described energy investments as the world transitions to a low carbon economy.

  • Dominant global players have yet to emerge in wind and solar
  • Handful of clean-energy companies build `supermajor’ skills

More than a decade after the birth of the modern renewable energy industry, solar and wind await their John D. Rockefeller.

Bloomberg – Clean power remains a tumultuous and fragmented business, crowded with companies grabbing for slices of an emerging market that aspires to reshape how the world meets its energy needs. They rise and fall as technology advances and demand seesaws. Some have grown into sprawling regional players, often propped up by government subsidies. A few, like Suntech Power Holdings Co. and Q-Cells SE, soared to prominence, then all but flickered out.

Yet there are still no companies that dominate the industry. Tiếp tục đọc “Waiting for a Rockefeller: Meet the Next `Supermajors’ of Energy” →

eco-business – Global momentum is building towards greater investment in renewables. Renewable energy is no longer seen as an indulgence that needs to be tolerated. Prospects are looking bright for the renewable energy industry as a growing number of countries, including the United States are realizing that the rapidly increasing use of renewable energy has become a beacon for optimism.

In fact, renewable energy sources are becoming affordable thanks to enhanced infrastructure and policies. Over the next decades, huge investments will be flowing into the energy sector. It is critical to seek ways to green those investments. According to UNEP’s 9th “Global Trends in Renewable Energy Investment 2015,” renewables are growing rapidly in both developed and developing countries, with China leading the way.

cleantecnica – The Fraunhofer Institute has found that Germany made about €1.7 billion, or $1.93 billion, in 2014 by selling surplus electricity. In 2015, that amount could reach €2 billion or $2.2 billion. Germany may also achieve a record export surplus of 40 TWh of electricity in 2015. “Over the past years, Germany was able to secure higher prices for its electricity exports than it paid for electricity imports,” explained Fraunhofer professor, Bruno Burger.

germancliffsRenewables added 118 TWh of energy production capacity in Germany from the period beginning in 2010 through 2014. What are some of Germany’s other exports? According to one source, Germany exported about $2.6 billion in pharmaceuticals to Japan in 2014. In 2007, cheese exports were about €2.7 billion.
