The Adolf Goetzberger Award, which recognizes innovation in solar, energy storage, smart grids, and power system efficiency, has invited applications for 2026, following a successful debut in 2025. The award once again spotlights developments that combine technological excellence with practical value and societal impact, according to the organizers.
The EUR 25,000 Adolf Goetzberger Award, named after German physicist and solar energy pioneer Adolf Goetzberger, honors individual contributions to forward-looking concepts, prototypes, or processes in photovoltaics, solar thermal energy, energy storage, smart grid integration, and system efficiency. Systemic and cross-disciplinary solutions are expressly welcome, the Adolf Goetzberger Foundation said.
The innovations should make a tangible contribution to sustainable energy system transformation
What matters is that the innovations address real-world technical and economic challenges and make a tangible contribution to the sustainable transformation of the energy system, reads a press release from the foundation, which is dedicated to promoting science and research, environmental protection, and climate action, with a particular focus on solar energy.
The inaugural Adolf Goetzberger Award was handed out in March 2025 to Heribert Schmidt for developing the HERIC® (highly efficient and reliable inverter concept) topology. The 2026 award ceremony will be held next spring.
Awarding innovation that makes the world a better place
“Innovation starts with a clear goal: making the world a better place. That’s the mission behind the Adolf Goetzberger Award. We aim to spotlight solutions that truly move the needle – technologically sound and socially relevant,” said Thomas Nordmann, Chair of the Adolf Goetzberger Foundation Board of Trustees.
This year’s award has an expanded scope
In addition to traditional entries from photovoltaics and solar thermal energy, the award now also invites cross-sectoral approaches, such as the smart combination of multiple technologies, advanced control and automation systems, innovative storage solutions (including power-to-X), the integration of heat pumps, or efficiency improvements in hybrid systems.

In addition to the EUR 25,000 cash prize, recipients will receive a certificate recognizing their contribution to the energy transition. Applications can be submitted online at Goetzbergerstiftung.de.
The Commercial Court in Kosovo* supported the claims filed by one company in a complaint, suspending its obligation to purchase electricity in the free market. The ruling follows protests against the controversial liberalization of the power market for larger firms, which came into force on June 1.
Two old coal-fired power plants in Kosovo* account for 92% of domestic production, which is the highest level in the world. Outages often prompt expensive emergency imports of electricity. Just last week, all operational coal units malfunctioned, while one in Kosovo B has been under reconstruction since last month.
Nevertheless, the authorities pushed through a controversial liberalization of the market for companies with more than 50 employees or an annual turnover of more than EUR 10 million. The measure, which came into force on June 1, led to two large protests. Almost 1,300 firms must purchase electricity in the free market.
However, the Commercial Court in Kosovo* suspended the obligation for REKS in a recent first-degree ruling. The company filed a complaint after it wasn’t allowed to use universal supply. It argued that it faced irreversible financial damage.
KEK signs few commercial power purchase contracts
The designated supplier of last resort is government-controlled Kosovo Energy Corp. (KEK). It is the operator of the Kosovo A and Kosovo B coal plants. Corporate consumers can opt for contracts of up to six months with the supplier of last resort.
KEK said a week ago that 360 such deals have been signed and that another 540 were coming. It only had 16 commercial contracts until that point.
Kosovo Chamber of Commerce claims KESCO is favored in liberalization
In the interpretation of the Kosovo Chamber of Commerce (KCC or OEK), the new court ruling means the entire power market liberalization needs to be suspended.
Conversely, the Energy Regulatory Office (ERO) said that last week the Basic Court of Prishtina rejected the motion that the chamber filed challenging the regulator’s public notice on the matter, which it issued in March.
KCC suggested that KESCO was favored in the switch, citing the lack of offers to consumers from other power suppliers. Dozens of other companies have also filed complaints, it added. The chamber called for a fair and feasible transitional phase and the creation of a clear plan that would ensure the stability for businesses and citizens.
Also of note, the Commercial Court said REKS’s gross income last year amounted to just EUR 6.5 million.
In other news, the opposition Democratic Party of Kosovo (PDK) said it would challenge ERO’s decision at the Basic Court because of the potential increase in electricity prices due to the liberalization.

The Romanian Ministry of Energy has signed 29 more grants to public entities for investments in solar power plants for self-consumption, bringing the total number of projects under the program to 1,046. The latest round of grants is worth EUR 11.3 million, putting the total sum approved so far at EUR 502 million.
The 29 grants, financed from the European Union’s Modernisation Fund, will help build solar power plants with a total installed capacity of 9.13 MW at schools, hospitals, city halls, and other institutions across Romania. It brings the total installed capacity supported under the program to over 403 MW, according to a press release from the Ministry of Energy.
The latest batch of projects puts the total planned capacity at over 403 MW
In many cases, installed renewable capacities cover up to 70% of the energy needs of public institutions, the ministry noted.
Romania’s outgoing Minister of Energy Sebastian Burduja hailed the program as a “paradigm shift,” noting that Romania was already in a new energy era, with local communities no longer just consumers, but active participants.
“Over the past two years, the Ministry of Energy has consistently provided support to local public authorities that understood the importance of investing in energy production for their own consumption. We have made funds available, simplified procedures, and worked side by side with beneficiaries so that the projects move forward quickly,” Burduja stated in a Facebook post.
The latest round of contracts covers public entities in 18 counties across the country: Arad, Argeș, Bacău, Brăila, Călărași, Constanța, Dâmbovița, Galați, Brașov, Gorj, Hunedoara, Maramureș, Mehedinți, Olt, Sibiu, Suceava, Teleorman, and Timiș.
The number of contracts has increased from 633 in March
In March, the ministry said it had signed 633 contracts, worth a combined EUR 339 million, of which EUR 294 million was from the Modernisation Fund. Total planned capacity at the time was 237.4 MW.

Despite early efforts to develop green hydrogen and its first regulatory framework, Greece finds itself on a steep curve.
The government has presented the first law on hydrogen and renewable gases in parliament. At the same time, refineries and other industries are working on projects that will determine green hydrogen’s cost-effectiveness.
However, a significant obstacle is the government’s unwillingness to support the new technology, either through subsidies or other financial instruments. The Ministry of Environment and Energy has specified that no upcoming technology would benefit from public funds. The goal is to maintain a low cost for the consumer during the energy transition.
According to Professor Pantelis Kapros from the National Technical University of Athens (NTUA), it means hydrogen will have to rely almost exclusively on the price of carbon. As the European Union’s European Trading System (EU ETS) is about to enter its second phase in 2026, the price of carbon allowances is projected to rise steeply.
Even so, market participants estimate that a ton of carbon dioxide equivalent would need to cost EUR 140, two times more than today, to make green hydrogen competitive against grey hydrogen, which is produced from natural gas.
Exports and power prices added to the equation
Regardless, Greece sees an opportunity to produce and export green hydrogen. The reason is its high renewables potential and production. The ever-increasing photovoltaic capacity has caused an overabundance of energy during the day. More demand is needed to balance the system and hydrogen can provide a way out.
Tsafos: We want to become a supplier
The hope is that the low renewable energy cost, combined with potential interest in shipping hydrogen abroad, will justify long-term investments.
“Our view is that as long as the market is interested, we want to become a supplier,” Deputy Minister of Environment and Energy Nikos Tsafos said at the Hydrogen & Green Gases Forum in Athens.
A potential problem is that green hydrogen plants are not expected to be viable if they only produce during the day, when renewable energy prices are usually lower. “Ten hours of operation are not enough to support producers and there are also technical issues to solve,” said Dimitris Kardomateas, head of the Center for Renewable Energy Sources and Saving (CRES).
He also pointed to the average daily wholesale power price, as it is higher in Greece than in most other European markets. It should be noted that electricity makes up about 70% of the total operating cost of electrolyzers.
Biomethane considered more mature
On the other hand, biomethane is considered much easier to develop. The technology depends less on power prices and also faces fewer technical hurdles. “Biomethane has a clear role, especially through its ability to enter the gas network, and we want to utilize it”, said Tsafos.
Gas distribution company Enaon EDA emphasized its readiness to include biomethane in its network. Its CEO Barbara Morgante noted that a study is underway to pinpoint the various existing and planned biomethane production plants around the country, as well as their proximity to Enaon’s network.
Biomethane is usually obtained by processing biogas to get methane of the same purity as in fossil gas. The renewable fuel can also be produced from clean hydrogen and CO2.
