Using machine learning and cheap satellite data to design rooftop solar power

Researchers at the University of Massachusetts, Amherst campus, have built a software tool, called DeepRoof, which they say has achieved a “true positive rate” of 91.1% in identifying a roof’s solar power potential, while using widely available (and cheap) satellite data from tools like Google Earth. Their goal in Deep Roof: a Data-Driven Approach For Solar Potential Estimation Using Rooftop Imagery, is to take a list of address (or GPS coordinates) from a contractor and hand back the solar power potential of those sites.

Solar companies are struggling to make sense of Indonesian government’s renewable energy policy

Solar power companies in Indonesia are struggling to maintain their margins. The Indonesian authorities have announced a renewable energy mix target of 23% by 2025. To push installations of renewable energy, the government has introduced various regulations through different ministries. But, companies are protesting against some of the regulations as they feel these are not conducive for national solar power development.

Cambodia electricity authority “in a race” to prevent 2020 cuts

The head of Electricite Du Cambodge (EdC) said yesterday (Aug 8) that the utility is in “a race against time and a race against nature” to get two new generators installed and commissioned ahead of the next dry season if power cuts similar to earlier this year are to be avoided...The unexpected shortage was a result of drought, Cambodia’s predominantly hydro based power generating systems left without sufficient water to turn the turbines.

Experts urge private investment in Vietnam’s power grid

Ninh Thuan and Binh Thuan provinces are increasingly burdened by overloaded transmission lines and substations. As more transmission lines and sub-stations get overloaded especially in Vietnam's Ninh Thuan and Binh Thuan provinces, state media reports that authorities have urged the government to allow investors to install transmission systems and transfer them to the Vietnam Electricity (EVN) for operation.

Solar power for houses (Indonesia)

The public campaign launched by Energy and Mineral Resources Minister Ignasius Jonan at the National Monument (Monas) in Jakarta on Sunday to promote rooftop photovoltaic (PV) solar panels is part of the government’s multifaceted push to develop clean energy. The campaign is timely as it comes after the Energy and Mineral Resources Ministry enacted a regulation late last year on licensing for the installation of rooftop PV solar panel systems and feed-in fees for exporting excess power into the grid of state electricity firm PLN. The regulation stipulates that the installation of a rooftop PV solar panel system requires prior verification and approval from PLN’s local distribution unit, a process that should be completed within 15 days.

BNEF: Energy to storage increase 122X by 2040

According to the latest forecast by BloombergNEF (BNEF), energy storage installations (not including pumped hydropower) around the world will multiply exponentially, from 9GW/17GWh deployed as of 2018 to 1,095GW/2,850GWh by 2040. The report goes on to model the impact of this on a global electricity system increasingly penetrated by low-cost wind and solar. Yayoi Sekine, energy storage analyst for BNEF and co-author of the report, said: “Two big changes this year are that we have raised our estimate of the investment that will go into energy storage by 2040 by more than $40 billion, and that we now think the majority of new capacity will be utility-scale, rather than behind-the-meter at homes and businesses.”

More floating PV for Thailand

Ciel&Terre and SCG have signed a memorandum of understanding to develop floating PV systems on hydroelectric dams in Thailand. Harold Meurisse, executive director of Sky & Earth Thailand, recently told the Bangkok Post that Thailand has always been a promising market. “This is a country where the solar industry is in demand for cost competitiveness without compromising the safety and quality of photovoltaic installations,” he said. “As a result, establishing a partnership with SCG has become natural, bringing together the best polymer and floating solar energy experts to seize the major opportunity of hybridization of the floating solar system and hydroelectric dams.”

P2P power model for rural areas: Renewables the main target under proposal (Thailand)

The Energy Ministry plans to promote a peer-to-peer (P2P) power trading model for private companies to decentralise the country's power generation system in line with the new version of the power development plan (PDP) for 2018-37. Energy Minister Sontirat Sontijirawong said Thai companies will have more chances to participate in this project, but the government will require companies to form joint ventures with small communities. Renewable power will be a key resource in P2P power trading -- including biomass, biogas, waste and solar -- depending on the potential in each province.
