Home Storage Sales Rocket as Australia Moves Towards Standardisation


Australia’s energy and environment minister has hailed the country’s accelerating residential energy storage sales as a report has emerged from Chief Scientist Dr Alan Finkel which says the “financial equation is straightforward” for adding batteries to home PV systems.

Finkel’s office produced reports during 2017 which advised the government on the power market, opportunities and challenges for renewables and decarbonisation and the role of clean energy technologies in boosting the resiliency of energy networks across Australia. At the tail end of the year, he also published a report on the “transformative role” of energy storage.

Coal-Heavy Poland Moves to Renewables, Finally


But coal will be king for a long time.

Poland, Europe’s biggest exporter and second-biggest consumer of coal, is cautiously embracing renewables to improve the security of its energy supply and meet European Union targets.

At the end of last month, the country’s upper house of parliament approved the removal of clean power investment roadblocks within a new renewable energy law aimed at putting Poland back on track to meet its EU commitment of 15 percent renewables by 2020.

Arizona Regulator Seeks Efficient Path for 80% Clean Energy Rule


Arizona regulator Andy Tobin has filed a set of proposed rules that would implement his Arizona Energy Modernization Plan to put utilities on a course to supply 80% renewable or nuclear power by 2050.

Tobin's proposal is to merge his plan with the state's existing Renewable Energy Standard and Tariff (REST), which he says would create no new credits or other rulemaking dockets.

California Lawmakers Push 100% Clean Energy Bill Closer to Governor's Desk


  • A California Assembly committee voted 10-5 in favor of raising the state's renewable energy target to 100%, giving new life to a proposal that had stalled last year.

  • Senate Bill 100 would require the state to utilize only renewable and zero-emission energy sources, including nuclear, by 2045. If Democratic Gov. Jerry Brown signs it, the bill would raise the state's current 2030 target of 50% renewables to a 60% interim target.

  • Hawaii is currently the only state with a 100% renewable energy mandate, but the state's unique geography, small population and abundant solar energy make it a poor comparison with California, which boasts the world's sixth largest economy.

Dive Insight:

By the end of 2017, about 43% of California's total electric system generation came from gas, followed by renewables at nearly 30% and large hydro at about 18%, according to the California Energy Commission. But the state's utilities are looking to avoid new gas plants or replace existing ones, adding further momentum behind the push to clean energy in the state.

Several other states are considering 100% clean energy mandates, including Massachusetts, New York, Oregon, Washington and Pennsylvania, according to Lauren Navarro, senior policy manager for Environmental Defense Fund's California programming. So far, only Hawaii has put such a goal into law.

Hawaii's goal of utilizing all renewable energy is an enormous task, but the ubiquitous sunshine and comparatively small size and population make it unique. California has 40 million residents — more than 10% of the country's population — and a 100% goal is evidence government leaders have confidence in the rapid advancement of clean energy.

The 100% renewables bill made progress in spring 2017 but stalled in the fall, facing pushback from utilities and lacking support in the Assembly. The Senate approved the measure last year in a 25 to 13 vote.

Bill author and Senate President Pro Tempore Kevin De León, D-Los Angeles, took to Twitter to praise the latest development. "We’re closer than ever to unlocking a clean-energy economy," he wrote.

The state's environmental goals and renewables targets are already aggressive, De León wrote. But rapid advances in green energy technology "shows that we have set the bar too low," he added.

Two years ago, California had 73% of the nation's solar capacity and produced 71% of the nation's utility-scale electricity generation from solar thermal resources, according to EIA. But the state still uses natural gas as its primary energy source. Nuclear energy also plays a significant role in California, but the state has charted a course to phase out all of its plants.

SB 100 now heads to the Assembly floor for consideration.

Polish Parliament Approves Changes to Green Energy Law


Poland’s upper house of parliament approved an amendment to the renewable sources of energy law on Friday meant to remove obstacles to green energy investment and help Warsaw meet EU renewable energy targets.

Poland’s conservative Law and Justice (PiS) party won the 2015 election partly with promises to sustain the traditional coal industry. In 2016, the government banned construction of new wind farms close to dwellings and imposed new taxes on investors that made many wind farms loss-making.

Forget the Duck Curve. Renewables Integration in the Midwest Is a Whole Other Animal

What is the Upper Midwest’s energy mascot? Fresh Energy’s Andrew Twite presents: the Smilin’ Gator Curve.

In the Great Plains, wind energy is cheap. Crazy cheap.

With the lowest levelized costs approaching $10 per megawatt-hour and thousands of megawatts being procured for under $20 per megawatt-hour, PPAs for new wind farms cost less than just the fuel required to run existing coal or natural gas plants.

California Tries Again With 3 Landmark Clean Energy Bills. This Time Things Are Different

The energy landscape has changed and last year’s obstacles may have shifted for 100 percent clean energy, grid expansion and a storage program.


The road ahead looks clearer for clean energy bills that stalled in Sacramento last year.

California has championed clean energy and climate change mitigation, but legislators last year failed to pass SB 100, a 100 percent clean energy bill authored by Senate leader Kevin De León and supported by Governor Jerry Brown. The bill would increase the state's renewable energy goal to 60 percent by 2030, and require entirely carbon-free electricity by 2045.

IRS Issues Favorable Tax Credit Guidance for New Solar Projects

“In the absence of this commence-construction guidance, tax equity partners were growing cautious about project risk.”


The Internal Revenue Service released a new guidance Friday that establishes when the construction of a solar facility starts to qualify for the solar Investment Tax Credit.

The guidance, Notice 2018-59, provides two methods for determining the "commence-construction" date: 1) starting physical work of a significant nature or 2) meeting the "5 percent safe harbor test" by incurring 5 percent or more of the total cost of the facility in the year that construction begins.

Nevada’s 2.3-Cent Bid Beats Arizona’s Record-Low Solar PPA Price




NV Energy’s portfolio of solar and solar-plus-storage takes the low-price competition up a notch.

Records don't last long in the cleantech business. 



Just days ago, we were reporting that the Central Arizona Project (CAP) had secured the lowest confirmed solar price in the U.S., when it approved a 20-year power-purchase agreement at $24.99 per megawatt-hour. That's setting aside an Austin Energy PPA from December that could be lower, but has more ambiguous terms.

China’s Bombshell Solar Policy Shift Could Cut Expected Capacity by 20 Gigawatts

Demand in China exceeding expectations? Analysts say “that is not going to be the case anymore.”


China’s recently announced changes to national solar policies will bring significant impacts for the global PV market and possibly the first contraction in global PV demand since before 2000, according to GTM Research. 

The country’s National Energy Administration, the National Development and Reform Commission and the Ministry of Finance released new guidance that terminates any approvals for new subsidized utility-scale PV power stations in 2018.

China will also reduce its feed-in tariff for projects by RMB 0.05 per kilowatt-hour (a fraction of a U.S. cent), cap distributed project size at 10 gigawatts (down from 19 gigawatts), and mandate that utility-scale projects go through auctions to set power prices. Projects connected to the grid past June 1 will not receive feed-in tariffs.

Demand Response Facing De-Rating in Irish Capacity Market



De-rating curves for other storage units by initial capacity and duration of storage at full output.


Demand side response in the Irish Capacity Remuneration Mechanism (CRM) is to face de-rating factors already applied to storage duration limits under new rules confirmed by the country’s electricity market authority.



For the forthcoming T-1 auction for capacity year 2019/20 the Single Electricity Market (SEM) Committee has ruled that Demand Side Units (DSUs) with a limited duration for their demand reduction of less than or equal to 6 hours will be hit with the same de-rating factors used for energy storage.

This ‘Maximum Down Time’ has been judged to be equivalent to a storage unit’s hours of storage as like short duration batteries, a DSU with limited demand reduction capabilities “does not deliver the same benefit to adequacy as a unit that does not limit its dispatch”, according to the SEM Committee.
These units will therefore have the same de-rating curves applied as those used for non-pumped storage assets

Out of the 15 responses to the CRM T-1 CY 2019/20 consultation, the SEM Committee says most agreed with the proposals, although some raised ‘material concerns’ with the use of other storage de-rating factors being applied to DSUs given they are totally different technologies.

Others claimed the plans also discouraged demand side response providers from participating with I-SEM and the capacity market by reducing the revenues which encourage businesses to contribute their capability to the stability of the system.

The plans have moved ahead of the proposal put forward in Britain’s capacity market by Scottish Power, which would see DSR bids using storage as part of its capacity placed in a new technology class and subject to de-rating factors recently applied to battery storage.

In response to the Irish decision Tom Palmer, principal consultant at Cornwall Insight, said: “The Irish Capacity Remuneration Mechanism for 2019/20 just became a lot more challenging for demand-side response providers.

“This is a step further than the proposal put forward in GB Capacity Market by Scottish Power for a Demand Side Response (DSR) Technology Classes with different minimum durations as that covered just storage.”

Further planning for the future

The SEM Committee has also looked further in planning for auctions taking place after the T-1 CY2019/20 auction, opting to change the methodology used to determine de-rating factors for energy storage.

These will be calculated as a function of both generation sizes and storage volumes in MW, or duration, given as the maximum number of hours all units sharing the energy storage (e.g. reservoir) can run simultaneously at their generation size before recharging.

Storage de-rating factors will be specified in 30 minute interval up to an energy storage duration of 6.5 hours and kept under periodic review, while a linear curve will apply to those units with a storage duration that is not a multiple of 30 minutes, applied between the nearest half-hour above and below a unit’s storage size.

To this end, an additional technology class is to be created on an enduring basis for “Other Storage” – not pumped hydro - and will apply the system wide outage statistics until there is sufficient SEM historical data.

The SEM Committee has also proposed to allow storage units a voluntary ‘decreasing tolerance’ (DECTOL) to allow them to continue to access and deliver other system services outside of the capacity market, thus avoiding penalties for not meeting their other obligations.

This means they can such units can apply a downward adjustment to the capacity they submit into the Capacity Market auction to reduce their exposure to difference payments in order to reflect their commitments to system services provisions.
