A little sharing leads to big savings for smart buildings

1 CommentBy

Smart buildings can be grid partners with utilities by shaving peak loads and increasing resiliency of the grid.

At peak times when utilities face heavy energy loads, smart buildings can shave demand on the grid. Thanks to electronic control systems, sensors, communications and on-site energy storage, buildings can charge their batteries when power is cheap and draw on their stored power during peak hours. Some utilities also give their customers reduced rates if they allow the utility to make momentary, unobtrusive adjustments in electricity loads during peak hours.

Automated demand response agreements enable utilities to remotely switch off their customers’ less critical systems for short periods of time during heavy demand on the grid — for example, turning off power to a hot water heater for five minutes. … Read More

Impact of solar eclipse on power grid shaped by solar

2 CommentsBy

On Monday, August 21, a rare total solar eclipse will cast a shadow across the U.S. – from the West Coast to the East Coast – for the first time in nearly 100 years. Almost a century ago, the modern power grid system was just getting its roots set in major cities. Now with solar power representing one percent of the U.S. energy generation mix and four percent of installed power capacity, this daytime darkness will have an effect on our power – but by how much?

According to the Energy Information Administration (EIA), the solar eclipse will obscure the sunlight at nearly 1,900 utility-scale solar photovoltaic (PV) power plants in the U.S.

While the direct shadow will last a mere three minutes, the entire event is expected to last three hours. … Read More

Unlock value with demand side response energy management

0 CommentsBy

Did you know that cost savings and sustainability initiatives often go hand-in-hand? Below, JLL’s Usama Sapru explores the benefits that demand side response energy management can bring to your business – impacting both the bottom line and helping you to achieve your sustainability objectives in the process.

It’s no secret that today’s building owners, occupiers and managers are under pressure to keep operating costs low – but they’re also tasked with achieving increasingly aggressive sustainability objectives.

The good news? Striking a balance between the bottom line and social responsibility is possible – and in some cases, even profitable. When it comes to energy management, adopting a Demand Side Response (DSR) policy provides one such opportunity.

What is Demand Side Response?Demand side response energy management

In the UK, the Department of Energy and Climate Change (DECC) estimates that electricity demand in the region will double by 2050. At the same time, there is a growing need to source cleaner electricity – especially given that conventional power stations are highly polluting and expensive to run (yet still required to meet peak demand and avoid blackouts).

Consequently, the National Grid System (NGS) is continuously changing the electricity supply to balance consumer demand and total generation requirements.… Read More
