Tesla plugs big batteries into PG&E’s electric grid

A row of tall white boxes by the side of a Sierra foothills highway could represent a key piece of California’s future electric grid. Made by Tesla, the boxes contain thousands of battery cells — the same cells that power Tesla’s luxury cars. But at this installation, at a Pacific Gas and Electric Co. substation in Browns Valley (Yuba County), the batteries soak up electricity whenever it’s cheap and feed it back onto the grid when demand hits its daily peak.

The project, operational since the start of the month, represents a collaboration between PG&E and Tesla on one of California’s biggest energy goals: storage.

Veolia CHP adds to renewable generation from food waste

Veolia has increased its capacity for generating renewable energy from food waste with a contract to design and manage a 520kWe biogas-fired combined head and power (CHP) energy plant for Rose Hill Recycling in Gloucestershire.

The CHP plant is fuelled by the biogas derived from mixed food waste collected from across the Cotswolds and will save around 1750 tonnes of CO2 emissions each year. The new CHP will increase the use of resources and make the site energy self-sufficient using renewable energy.

International Cogeneration Equipment Market 2020

The Cogeneration Equipment Market research report is a professional and in-depth study on the current state also focuses on the major drivers and restraints for the key players. Global Cogeneration Equipment Market is Projected to grow at 4.57% CAGR during the period 2016-2020. Cogeneration Equipment Industry research report also provides granular analysis of the market share, segmentation, revenue forecasts and geographic regions of the market.

The cogeneration process involves simultaneous production of heat and electricity from a single source. This technology evolved a century ago along with steam turbine power plants. The world’s first central power station was also the first cogeneration plant that was commissioned in Manhattan in 1884. Though the technology is century old, it garnered attention from the 1980s as technological advances led to improved cogeneration cycle efficiency. Over the years, emergence of new technologies for power generation coupled with enhanced cycle efficiency fueled the sales of cogeneration equipment.

Guide to assessing viability of cogeneration projects published by ENER-G

Manchester, UK — Cogeneration specialist ENER-G has published a free guide to assessing the economic feasibility of combined heat and power (CHP) projects.

The guide, which is available to download, details the steps that building engineers and energy and facilities managers should take to prove the viability of a proposed CHP scheme to investors or board members.

A good quality CHP system will typically generate a return on investment within three to five years, and generate cost savings over 15 years or more. This, however, depends on ensuring that CHP is the right solution for the particular site and sizing the system accurately to optimise efficiency and performance.

Wind briefly sets record as source for electricity in U.S.

Wind briefly powered more than 50 percent of electric demand on Feb. 12, the 14-state Southwest Power Pool (SPP) said, for the first time on any North American power grid.

SPP coordinates the flow of electricity on the high voltage power lines from Montana and North Dakota to New Mexico, Texas and Louisiana.

Wind power in the SPP region has grown significantly to over 16,000 MW currently from less than 400 megawatts in the early 2000s and is expected to continue growing. One megawatt can power about 1,000 homes.

Hard times for Kenyans as electricity prices go up, again

Kenyans should brace for another round of power price hikes following the weakening of the shilling against the US dollar which has seen a rise in foreign exchange levy component of the monthly electricity bill. In its latest review of some cost components that make up the monthly bills, the Energy Regulatory Commission (ERC) increased the foreign exchange levy to Sh1.28 per unit of electricity for power consumed in February. This is a steep rise from 84 cents per unit charged for electricity consumed in January.

California businesses don’t benefit from abundance of electricity

California likely is the leading state for promoting energy efficient operations and renewable energy generation. It seems logical that this would lead, over time, to lower electric bills for its businesses.

It’s logical – but wrong. In fact, ratepayers in the state are paying a lot more than those elsewhere, according to a story in the Arizona Daily Sun. The reason is simple: Though subscribers are cutting their use – through voluntary steps and state mandates – rate hikes to finance power plants already are on the books. The story says that those increases will come, regardless of the fact that the extra capacity is not needed.
