The Clean Growth Strategy puts faith in energy efficiency – here’s how to do it


The UK government’s new Clean Growth Strategy gives quite a lot of priority to energy efficiency. That’s good news, write Jan Rosenow and Richard Cowart. What’s needed next is to develop the policies that actually deliver the goods. This can be done by following the principle of Efficiency First.

The Clean Growth Strategy, launched by the UK government on October 12, is pretty ambitious when it comes to energy efficiency. Especially for buildings, the targets set out are laudable (all homes as far as possible should reach Energy Performance Certificate band C by 2035 and all fuel poor homes by 2030).

What is still missing, however, are the policies to deliver on the ambition. This is what we have tried to provide in a report, published this week, which explains how ambitious decarbonisation goals can be met efficiently by implementing the principle of “Efficiency First.”

What is Efficiency First?

More than £200 billion will be invested in new energy supply infrastructure over the coming years, ultimately out of the pockets of energy consumers. But very little attention is devoted to reducing the need for such investment in the first place. The U.K. needs to meet the demand for energy services more efficiently and more flexibly on the demand side. This not only avoids more costly investments in energy infrastructure and fuel, it is essential to the cost-effective, timely decarbonisation of the economy. In recognition of this key strategy, the National Infrastructure Commission, an official advisory body to the UK government, named energy efficiency as the first priority for achieving a low-cost, low-carbon future in a new report published on 13 October.

“Rolling out energy-efficiency measures may well defer or avoid the need for costly network enhancement.”

This decision-making logic has been coined Efficiency First. It is a principle applied to policymaking, planning, and investment in the energy sector. Put simply, it prioritises investments in customer-side efficiency resources (including end-use energy efficiency and demand response) whenever they would cost less, or deliver more value, than investing in energy infrastructure, fuels, and supply alone.

But does this really work? Here’s a concrete example from New York: In 2014, Consolidated Edison (ConEd), one of the world’s oldest utility companies, faced a $1.2 billion substation upgrade because electricity demand for the Brooklyn-Queens area was increasingly putting stress on the distribution system. Most network companies would have simply approached the substation upgrade in the old-fashioned way. ConEd, however, decided to do things differently. They designed a $200 million demand-side management programme instead. So far, participating customers include about 6,000 small businesses, 1,400 apartment blocks, and 8,800 homes. Participants have reduced load on the distribution system, while reducing their own energy bills. Now, ConEd is rolling out this successful approach across different neighbourhoods.

How can this be applied in the UK?

In RAP’s new report, we identify a number of key areas where we see potential for the Efficiency First principle to lower emissions, whilst also delivering a wide range of benefits associated with energy efficiency improvements. In particular, we focus on Efficiency First in the context of policy decisions that will be made over the next years, including the design of a new able-to-pay energy efficiency programme, energy network regulation, infrastructure spending, revisions of the capacity mechanism, and the levy control framework.

For example, one area where Efficiency First can be applied imminently is network regulation—this is also one of the ideas on which the government consulted in its call for evidence on building a market for energy efficiency. Ofgem, the Office of Gas and Electricity Markets, is currently reviewing its RIIO price control framework for network companies. In its open letter to stakeholders, Ofgem stated that “rolling out energy-efficiency measures may well defer or avoid the need for costly network enhancement.” Building on RIIO’s current outcomes and incentive structure, Ofgem should introduce additional incentives and/or primary and secondary deliverables that provide impetus for energy efficiency investment by the network companies. This would reduce the need for network investment—a prime example of Efficiency First in practice.

What needs to happen next?

Before billions of consumer-funded pounds are locked into new energy supply infrastructure, we should ask the simple question, “Where can we reduce the need for supply-side investment through energy efficiency and more flexible demand?

We recommend that the U.K. government build on the momentum around Efficiency First by carrying out a systematic review of how this principle can be applied to all other energy policy areas and then drafting an appropriate action plan. Both Germany and the EU are already investigating where and how the Efficiency First principle should be applied across the energy system. In the U.K., network regulation provides a promising opportunity to jump-start this process.

Adopting a “hard look” policy to examine and invest in Efficiency First is the most important step the government can take toward unlocking the huge reservoir of low-cost, low-carbon savings that sits untapped in every part of the U.K.
