Mexico’s Wind Speeds Below Average, Vaisala Says
Many regions of Mexico experienced wind speeds up to 20 percent below average throughout 2015, according to performance maps released in February by Vaisala. The Oaxacan coast, where a majority of operational wind power projects are located, saw high levels of month-to-month variability, Vaisala said.
As Mexico moves to add more wind energy capacity – as much as 10 GW over three years – insight into seasonal and year-to-year wind variability will be critical for operators, Vaisala noted.
Vaisala’s performance maps show that in northern and central Mexico, Q1 wind speeds were 5-20 percent below normal. The trend weakened in Q2 and Q3, but wind speeds remained below average. A shift in weather patterns with elevated wind speeds across much of northwestern Mexico in Q4 was consistent with the strong El Niño climate signal as well as some hurricane activity in the region, Vaisala said.
Hawaii Seeks to Protect State-Level Oversight of Geothermal Development
The Hawaii legislature is considering a bill to ensure that regulations concerning development of geothermal resources are not subject to local restrictions.
The bill would clarify that regulation of geothermal resources is exclusively reserved to the state, and would require rules regarding geothermal exploration and development be uniform throughout the state.
Supporters of the bill claim the adoption of county-level regulations can conflict with state regulation and interfere with the ability of a geothermal energy producer to safely and efficiently conduct exploration or production activities, leading to an increase in the cost of production or loss of investment in the production of additional geothermal resources. Opponents claim the state has a poor record of regulating geothermal development and local rules would protect residents.
Hawaii Senate Committees on Transportation and Energy; Public Safety, Intergovernmental, and Military Affairs; and Water, Land and Agriculture recommended passage of the bill.
UK Government to Review Tidal Lagoon Energy
The U.K. government on Feb. 10 said it has commissioned an independent review into the feasibility and practicability of tidal lagoon energy in the U.K.
The Department of Energy & Climate Change said in a statement that the review will begin in the spring, and that it expects the proposed developers of the Swansea Bay Tidal Lagoon project, and other industry stakeholders to take part in the review.
In a statement, Keith Clarke, chairman of Tidal Lagoon Swansea Bay Plc, developer of the Swansea Bay project, welcomed the independent review, saying: “In parallel to the review, we have been asked by government to clarify the financial and technical viability of Swansea Bay Tidal Lagoon as the pathfinder for this exciting new industry. This is particularly encouraging as it signals the strength of our offer for Swansea Bay and our future program of lagoons.”
The Swansea Bay proposal includes an energy-generating lagoon with a 320 MW installed capacity and 14 hours of generation daily.
ElectraTherm Delivers Second Biomass-fuel Generator in UK
Waste-to-heat power generation provider ElectraTherm said in February that it has shipped its Power+ generator 4400 to a chicken farm in the U.K.
Slated for a spring 2016 commissioning, the site uses a combination of biomass and combined heat and power (CHP) technology, and is the second Power+ installation in the country.
According to ElectraTherm, its generator uses organic rankine cycle (ORC) and proprietary technologies to generate power from low-temperature heat ranging from 77-122 degrees C. At this chicken farm, the operator uses woodchips to heat a 600-kW biomass boiler to 116 degrees C. The boiler heats water to run the Power+ generator, and produces clean electricity that is sold back to the utility. ElectraTherm said that the Power+ system also acts as a CHP system, and remaining heat from ElectraTherm’s condenser helps dry wood chips as part of the biomass processing.
“The addition of ORC technology is a critical component of our operations, and the benefits of the Power+ generator are proven with more than 50 machines in the field and more than 500,000 hours of operational runtime,” Mick Jones, director of distributor Woodtek Energy, said in a statement.

Altitec said the deal enables the two businesses to deliver a range of wind turbine blade and tower services to wind farm owners, operators and original equipment manufacturers operating in the South African market.
The South African wind energy market has grown rapidly in recent years with 15 new wind farms totaling 1,200 MW constructed in the last three years, according to Altitec.
As part of the joint venture agreement, Altitec is training new South African rope access technicians to international standards.
The range of core certified services delivered within the joint venture includes rotor-based inspections based on the principles for the monitoring of wind turbines, composite blade repairs, cleaning and monitoring of equipment and wind turbine tower corrosion protection and repair.
Australian Fringe-of-Grid Solar Project Receives Funding
The Australian Renewable Energy Agency (ARENA) said it is providing $8.4 million for Canadian Solar and Scouller Energy to construct a 5-MW DC solar project near Normanton in Queensland, Australia, to demonstrate how integrating solar into the grid can improve energy reliability.
“Like many regional Australian communities, Normanton is on the fringe of one of our major electricity networks,” ARENA CEO Ivor Frischknecht said. “Adding renewable energy generation closer to where it’s needed can provide more reliable and efficient power. This is a key ARENA investment focus for fringe-of-grid and network constrained areas.”
According to Frischknecht, the Normanton project will be a test case for network provider Ergon Energy to understand the effects on network losses. The Normanton solar project will be jointly owned by Canadian Solar and Scouller Energy.
The project is scheduled for completion in December.
