IBM introduces new wind and solar forecasting system for utilities; big data analytics and weather modeling to predict output

Green Car Congress

The solution combines weather prediction and big data analytics to forecast accurately the availability of wind power and solar energy. This will enable utilities to integrate more renewable energy into the power grid, the company says. This amount of additional energy can power roughly more than 14,000 homes.

PNNL study finds 2028 grid resource adequacy likely sufficient for high EV penetration; managed charging strategies can double adequacy

Green Car Congress

A new study of the impact of high EV adoption on the Western US power grid by a team from Pacific Northwest National Laboratory (PNNL) has found that 2028 grid resource adequacy—from generation through transmission—is likely to be sufficient for high EV penetration.

Yet, its natural gas output will still comprise 85% of its total production by the end of the forecast period. Natural gas does produce about 28% less CO2 emissions than heating oil and 50% less than coal for the same amount of energy when burned.

In addition, despite the rigorous development of renewables, carbon dioxide emissions are increasing, because the energy mix increasingly includes coal-fired power plants that emit large quantities of CO 2 to compensate for weather-related fluctuations in power generation from renewables and the closing of nuclear plants.

US installs 6.2 GW of solar PV in 2014, up 30% over 2013

Green Car Congress

Solar accounted for 32% of US new generating capacity in 2014, beating out both wind energy and coal for the second year in a row. GTM Research forecasts the US PV market to grow 31% in 2015. The utility segment is expected to account for 59% of the forecasted 8.1 GW) is coal-fired generation. GW), natural gas (6.3

CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power

Green Car Congress

To compensate for the increased amounts of these inherently–variable sources of electricity, the power grid requires additional flexibility to manage fluctuations in generation. They used hourly data for wind and load and assumed perfect information (no forecast error) to focus on capacity expansion and unit commitment decisions.
